RESUMEN

BACKGROUND: Information on large groups of patients with acrodermatitis chronica atrophicans (ACA) is limited. METHODS: We assessed clinical and microbiological characteristics of patients with ACA diagnosed at a single medical centre and compared findings in periods 1991-2004 vs. 2005-2018. The cohort is representative of Slovenian ACA patients. RESULTS: We assessed 693 patients: 461 females and 232 males, with median age of 64 years. Median duration of ACA before diagnosis was 12 months. In all but 2 patients, the skin lesions were located on extremities, more often on the lower (70.0%) than the upper (45.2%), bilaterally in 42.4%. Reddish-blue discoloration, swelling, thinning and wrinkling of skin were present in 95.2%, 28.1%, 46.4% and 20.5% of patients, respectively. Overall, 64.4% of patients reported constitutional symptoms, 23.1% had local symptoms, and 20.8% had symptoms/signs of peripheral neuropathy. Nodules, arthritis, joint deformity, muscle atrophy and paresis were rare (<3%). Borreliae were isolated from 200/664 (30.1%) skin samples; 92.8% were Borrelia afzelii. B. garinii and B. burgdorferi s.s. were more often isolated from the skin of male patients (OR = 4.17) and from those with arthropathy (OR = 11.74). Patients included in the more recent period were older, complained less often of constitutional symptoms but more often of local symptoms, and more often had local swelling but less often skin atrophy and bilateral involvement, probably as a consequence of earlier diagnosis. CONCLUSIONS: ACA, typically caused by B. afzelii, usually affects older women. Clinical presentation depends on the duration of illness and probably on the Borrelia species causing the disease.

RESUMEN

Spirochetes from the Borrelia burgdorferi sensu lato (s.l.). (Spirochaetales: Spirochaetaceae) species complex, including the causative agents of Lyme borreliosis, have been isolated from ticks, vertebrate reservoirs and humans. Previous analyses based on direct molecular detection in ticks indicated a considerable diversity of B. burgdorferi s.l. complex in Serbia. The present study aimed (a) to isolate borrelia strains from Serbia; (b) to determine their genotypic characteristics; and (c) to establish a collection of viable B. burgdorferi s.l. strains for further biological, ecological and genetic studies. For the present study, 231 adult Ixodes ricinus (Ixodida: Ixodidae) ticks from 16 ecologically different localities in Serbia were individually processed to cultivate B. burgdorferi s.l. This led to the isolation of 36 strains. A hbb gene quantitative real-time polymerase chain reaction (PCR) based on melting temperature determination and ospA gene sequencing were used to genotype the isolated spirochetes. The species identified based on the hbb gene real-time PCR were: Borrelia lusitaniae (44.4%), Borrelia afzelii (36.1%), Borrelia garinii (13.9%) and Borrelia valaisiana (5.6%), whereas the ospA sequence analysis revealed the occurrence of Borrelia bavariensis. This is the first report of the isolation of B. lusitaniae, B. garinii, B. bavariensis and B. valaisiana strains in Serbia.

RESUMEN

The aim of the study was to evaluate two culture media for Borrelia burgdorferi sensu lato isolation from a 5 × 2 × 2 mm skin biopsy that was dissected into two pieces and inoculated into modified Kelly-Pettenkofer (MKP) and Barbour-Stoenner-Kelly-H (BSK-H) medium. Samples were incubated at 33°C for up to 9 weeks. Borrelia species was determined by MluI-restriction of whole genome or by MseI-restriction of PCR product. We determined the proportion of isolation rate, 'slow-growers', contaminated specimens and Borrelia species in the two media. In each of the two media 235 skin specimens were cultivated. We found 90/470 (19.1%) contaminated cultures (BSK-H 67/235, 28.5%; MKP 23/235, 9.8%; p <0.0001). Borrelia growth was ascertained in 59/235 (25.1%) BSK-H and 102/235 (43.4%) MKP cultures (p <0.0001); the corresponding values for non-contaminated cultures were 59/168 (35.1%) and 102/212 (48.1%); (p 0.003). Fourteen specimens were positive only in BSK-H, 57 solely in MKP, and 43 in both culture media. Slow growth was present in 8/59 (13.6%) BSK-H and in 4/98 (4.1%) MKP positive cultures (p 0.019). Borrelia afzelii was identified in 44/51 (86.3%) BSK-H and in 88/98 (89.8%) MKP culture-positive samples; the corresponding findings for Boreelia garinii and B. burgdorferi sensu stricto were 6/51 (11.8%) and 9/98 (9.2%), and 1/51 (1.9%) and 1/98 (1.0%), for BSK-H and MKP, respectively. Comparison of MKP and BSK-H medium for Borrelia culturing from skin specimens of European patients with erythema migrans revealed the advantage of MKP over BSK-H.

RESUMEN

The aims of the present study were to assess the concentrations of different cytokines and chemokines in blood serum and cerebrospinal fluid (CSF) samples of patients with Lyme neuroborreliosis and to identify the possible marker(s) that would enable a distinction between clinically evident and suspected Lyme neuroborreliosis, as well as between Lyme neuroborreliosis and tick-borne encephalitis (TBE). Our additional interest was to evaluate the relationship between cytokine and chemokine concentrations and Borrelia burgdorferi sensu lato isolation from CSF, as well as intrathecal synthesis of specific borrelial antibodies. We found that higher concentrations of CXCL13 and lower concentrations of interleukin 10 (IL-10) in serum were associated with higher odds for clinically evident Lyme neuroborreliosis compared to suspected Lyme neuroborreliosis, as well as to TBE. The concentrations of IL-2, IL-5, IL-6, IL-10, and CXCL13 in the CSF were higher in patients with evident Lyme neuroborreliosis than in those who were only suspected to have the disease. A comparison of CSF cytokine and chemokine levels in patients with and without intrathecal synthesis of specific borrelial antibodies revealed that CXCL13 CSF concentration is significantly associated with intrathecal synthesis of borrelial antibodies. A comparison of the cytokine and chemokine CSF concentrations in patients with clinically evident Lyme neuroborreliosis according to CSF culture results revealed that higher concentrations of gamma interferon (IFN-γ) were associated with lower odds of Borrelia isolation. Although several differences in the blood serum and CSF concentrations of various cytokines and chemokines between the groups were found, the distinctive power of the majority of these findings is low. Further research on well-defined groups of patients is needed to appraise the potential diagnostic usefulness of these concentrations.

RESUMEN

BACKGROUND: Reports on patients with European Lyme borreliosis in whom borreliae were isolated from the blood are rare and nearly exclusively limited to those with solitary or multiple erythema migrans. Here we report on patients with other manifestations of Lyme borreliosis in whom borreliae were isolated from their blood. PATIENTS AND METHODS: This is a retrospective review of the medical files of patients diagnosed with borrelial lymphocytoma, Lyme neuroborreliosis, Lyme arthritis and acrodermatitis chronica atrophicans at the Department of Infectious Diseases of the UMC Ljubljana, Slovenia, for whom a borrelia blood culture was ordered. The clinical features of patients whose blood culture tested positive for Borrelia burgdorferi sensu lato were reviewed, and the association between the proportion of patients with a positive blood culture and various clinical manifestations was examined. RESULTS: Borrelia burgdorferi sensu lato was isolated from the blood of 1/53 (1.9%) patients with borrelial lymphocytoma, 6/176 (3.4%) patients with Lyme neuroborreliosis, 1/13 (7.7%) patients with Lyme arthritis, and 3/200 (1.5%) patients with acrodermatitis chronica atrophicans. The time interval from the onset of symptoms attributed to Lyme borreliosis and the blood culture ranged from 1 day to >2 years (median 3.5 weeks). At the time of the blood culture, erythema migrans was present in 4/11 (36.4%) borrelia blood culture-positive patients, i.e. in the patient with borrelial lymphocytoma, the patient with Lyme arthritis and the 2/6 patients with Lyme neuroborreliosis. Only two of these 11 (18.2%) patients had fever at the time of the blood culture. CONCLUSIONS: In European patients with Lyme borreliosis, borreliae can be cultured from the blood not only early in the course of the disease but also occasionally later during disease progression.

RESUMEN

We report the first documented case of OXA-48-producing Klebsiella pneumoniae in Slovenia isolated from rectal surveillance cultures from a patient transferred from Libya. The patient was colonised with both ESBL-producing Escherichia coli and ESBL- and OXA-48-producing K. pneumoniae. Three further patients were colonised with ESBL-producing E. coli. This underscores the importance of an early warning system on European level and screening upon admission of patients transferred across borders and between healthcare systems.

RESUMEN

AIMS: In 2003, pseudorosettes were described as highly suspicious of infection by Borrelia burgdorferi sensu lato in the appropriate clinical context. Nevertheless, such a pattern has been described in the literature in other non-infectious conditions. On the other hand, granuloma annulare (GA) has been recently closely associated with infection by Borrelia. We investigated how frequently pseudorosettes can be detected in common GA cases confirmed for Borrelia by PCR. METHODS AND RESULTS: We studied 13 biopsies of non-interstitial GA and 2 biopsies of interstitial GA from patients without clinical suspicion of borrelial infection. We also performed immunohistochemical studies in all the biopsies, using the CD-68 antibody. Molecular studies with PCR were performed with beta-globin PCR (human DNA). Borrelial DNA was confirmed by amplifying the OspA gene and intergenic rrf-rrl region. We found histiocytic pseudorosettes in 13 biopsies (86.66%). Human DNA was successfully amplified from 8 of 13 paraffin-embedded skin samples. From these we amplified borrelial DNA in 5 of 8 samples. Out of the 8 cases in which human DNA was amplified, a correlation between pseudorosettes and the molecular tests (Borrelia DNA) was confirmed in 5 instances. CONCLUSIONS: a) Pseudorosettes are not an unusual finding in common granuloma annulare; b) Borrelia is present in (most) cases of granuloma annulare; and c) Pseudorosettes seem to be a good morphological sign predictive of infection with Borrelia in granuloma annulare.

RESUMEN

The sensitivities of two PCR assays and culture were compared for the detection of Borrelia spp. in skin specimens of 150 patients with typical erythema migrans. In addition, the accuracy of the methods for the identification of Borrelia spp. was compared by analysing culture isolates and material obtained directly from skin biopsy specimens. Borrelia burgdorferi sensu lato was isolated from 73 (49%) of 150 skin biopsy specimens. Using a nested PCR targeting the rrf-rrl region and a PCR targeting the flagellin gene, 107 (71%) and 36 (24%) specimens, respectively, were positive. With both PCRs, positive results were more frequent with culture-positive samples (67/73 (92%) and 24/73 (33%) for the nested and flagellin PCRs, respectively) than with culture-negative samples (40/77 (52%) and 12/77 (16%) for nested and flagellin PCR, respectively). Pulsed-field gel electrophoresis after MluI restriction identified 69/73 (95%) isolates, of which 58/69 (84%) were Borrelia afzelii and 11/69 (16%) were Borrelia garinii. After MseI restriction of PCR products amplified from the intergenic rrf-rrl region, B. afzelii was identified in 73/107 (68%) samples, B. garinii in 22/107 (21%) samples, and both species in 11/107 (10%) samples. The corresponding results for culture-positive specimens were 41/69 (59%), 14/69 (20%), and 7/69 (10%). Comparison of the results for specimens positive according to both approaches revealed complete uniformity in 80% of the cases. Overall, nested PCR was the most sensitive method for the demonstration of Borrelia spp. in erythema migrans skin lesions, followed by culture and PCR targeting the flagellin gene. The congruence of identification results obtained by analyzing culture isolates and material obtained directly from skin biopsies was relatively high but incomplete.

RESUMEN

BACKGROUND: The most common cause of Lyme neuroborreliosis in Europe is Borrelia garinii, followed by Borrelia afzelii. However, no series describing patients with culture-confirmed cases of Lyme neuroborreliosis have been published, and no comparison of findings for patients with B. garinii and B. afzelii isolated from cerebrospinal fluid (CSF) has been reported. METHODS: All adult patients identified at a single medical center during a 10-year period who had borreliae isolated from CSF and typed as B. garinii or B. afzelii (using large DNA fragment patterns obtained with the MluI restriction endonuclease and separated with pulsed-field gel electrophoresis) were included. RESULTS: A comparison of 23 patients who had B. garinii isolated from CSF with 10 patients who had B. afzelii isolated from CSF revealed that a reliable clinical diagnosis of Lyme neuroborreliosis (before obtaining a CSF culture and intrathecal borrelial antibody production result) was established more frequently in the B. garinii group than in the B. afzelii group (19 of 23 patients vs. 1 of 10 patients). Patients in the B. garinii group reported radicular pains and expressed meningeal signs more often, but reported dizziness less often (occurrences of several other symptoms and/or signs were comparable). Lymphocytic pleocytosis, as well as several other CSF abnormalities, were frequent among patients with B. garinii isolated from CSF but were rare among patients in the B. afzelii group. CONCLUSIONS: Patients with B. garinii isolated from their CSF have a distinct clinical presentation, compared with patients with B. afzelii. B. garinii causes what, in Europe, is appreciated as typical early Lyme neuroborreliosis (Bannwarth syndrome), whereas the clinical features associated with B. afzelii are much less specific and more difficult to diagnose.

RESUMEN

BACKGROUND: We compared epidemiological and clinical characteristics of patients with erythema migrans (EM) caused by Borrelia afzelii and Borrelia garinii. PATIENTS AND METHODS: 200 consecutive adult patients with B. afzelii isolated from the skin lesion and 53 consecutive adult patients with EM caused by B. garinii qualified for the present study. RESULTS: Comparison of the two groups revealed several distinctions. Patients with EM caused by B. garinii were older, had their skin lesions more often located on the trunk but less often on extremities, had shorter incubation and faster evolution of EM, more often reported associated local and certain systemic symptoms, had abnormal liver function test results more often and were more frequently seropositive. CONCLUSION: Early localized Lyme borreliosis caused by B. afzelii and B. garinii has distinct epidemiological and clinical characteristics. Clinical features of EM depend upon the genospecies of Borrelia burgdorferi sensu lato causing the illness.

RESUMEN

BACKGROUND: Data on European children with erythema migrans (EM) are limited. PATIENTS AND METHODS: 553 patients, 333 with solitary and 220 with multiple EM, diagnosed between 1996 and 2000, were included in the prospective study. Demographic, clinical and laboratory data including borrelial serum immunofluorescence assay antibody titers and Borrelia burgdorferi sensu lato blood culture results were obtained; findings in solitary and multiple EM were compared. RESULTS: Comparison revealed that children with multiple EM were younger (4.5 vs 6.5 years; p = 0.0000), less often reported a tick bite at the site of later skin lesion (25% vs 46%; p = 0.0000), had a longer incubation period (22 vs 13 days; p = 0.0028), more frequently presented with a ringlike lesion (99% vs 86%; p = 0.0000), less often reported associated local (15% vs 41%; p = 0.0000) but not systemic symptoms (28% vs 26%, p = 0.6913), more frequently had abnormal findings on physical examination (35% vs 26%; p = 0.0264), and a higher frequency of laboratory abnormalities including the presence of borrelial serum antibodies as well as B. burgdorferi sensu lato isolated from blood (12% vs 6%; p = 0.0267); younger age and male sex were identified as risk factors for the isolation of Borrelia. 40/44 isolates were Borrelia afzelii. CONCLUSION: Analysis of a large group of European children with solitary and multiple EM revealed several demographic, clinical and laboratory differences between the two groups.

RESUMEN

Lyme borreliosis often presents initially with erythema migrans. Borreliae may disseminate from the primary skin lesion, and different organs and systems could be affected. Borrelia strains were isolated from blood of 70 patients with Lyme borreliosis, including 10 patients from whom borreliae were also isolated from skin. The aim of the present study was to characterise the isolates with regard to their phenotypic and genotypic characteristics. Borreliae were cultivated in MKP medium. Species identification and plasmid profiles were determined by pulsed-field gel electrophoresis (PFGE) and protein profiles by SDS-PAGE. Digestion of Borrelia burgdorferi sensu lato DNA showed 63 (90%) B. afzelii Mla1 and 7 (10%) B. garinii Mlg2. No B. burgdorferi sensu stricto were isolated. Borreliae were isolated from both skin and blood of 10 patients, nine pairs of isolates were identical: seven B. afzelii and two B. garinii. B. afzelii was isolated from the skin and B. garinii from blood of the tenth patient. All but one isolate possessed at least one large plasmid and varying numbers of smaller plasmids. Eight (11.4%) of 70 isolates possessed an unusual plasmid profile (2 of 63 B. afzelii and 6 of 7 B. garinii). Borreliae differed in their protein profiles. OspA and OspB proteins were expressed by all B. afzelii isolates; 85.7% of B. garinii isolates expressed OspA and 71.4% expressed OspB. OspC was expressed by 65% of B. afzelii isolates and all B. garinii isolates. The ratios of B. afzelii and B. garinii isolated from blood and skin were similar. These results do not support the hypothesis that B. garinii has a higher propensity for haematogenous dissemination than B. afzelii. Antigen diversity as well as species and plasmid heterogeneity could play a role in the pathogenesis of the infection, suggesting distinctive strain organotropism.

RESUMEN

BACKGROUND: We assessed the isolation rate of Borrelia burgdorferi sensu lato from blood in European patients with typical erythema migrans and evaluated the course and outcome of their illness. PATIENTS AND METHODS: Adult patients diagnosed with erythema migrans and from whom borreliae cultured from blood were included in this study. RESULTS: Borreliae were isolated from the blood of 35/2,828 (1.2%) patients, on average 7 days (range 1-47 days) after the appearance of erythema migrans. Only seven (20%) patients reported constitutional symptoms. 24/35 isolates were typed of which 20 were Borrelia afzelii and four were Borrelia garinii. 31 (88.6%) patients were treated with oral antibiotics while four (11.4%) received ceftriaxone iv. The course and outcome of the illness were favorable in all patients. CONCLUSION: In European patients with erythema migrans the yield of blood culturing was low, spirochetemia was often clinically silent and the course and outcome of the illness were favorable; the predominantly isolated strain was B. afzelii.

RESUMEN

OBJECTIVES: To establish the frequency of isolation of Borrelia burgdorferi sensu lato from blood of children with solitary erythema migrans (EM) in Europe, to determine the strains of the isolated borreliae and to compare the clinical course and the outcome of the disease according to positive and negative blood culture result. METHODS: In the prospective study we included 134 consecutive patients younger than 15 years with solitary EM, referred to our institution in 1996 and 1997. One milliliter of blood was withdrawn before treatment and cultured in modified Kelly-Pettenkofer medium. Isolated borreliae were typed according to LRFP analysis. Patients were treated with either penicillin V or cefuroxime axetil for 14 days. The posttreatment course was surveyed by follow-up visits during 1 year. RESULTS: B. burgdorferi sensu lato was isolated in 12 of 134 (9%) patients. Eleven blood isolates were typed: 10 were found to be B. afzelii and 1 was Borrelia garinii. Comparison of blood culture-positive and -negative patients revealed no differences in pretreatment characteristics or in posttreatment clinical course. However, worsening of local and/or systemic signs and symptoms at the beginning of antibiotic therapy (Jarish-Herxheimer's reaction) was identified more often in the blood culture-positive than in the blood culture-negative group (5 of 12 vs. 17 of 122, respectively; P = 0.0274). CONCLUSIONS: The isolation rate of B. burgdorferi sensu lato from the blood of children with solitary EM was 9%. The majority of the isolates were B. afzelii. Blood culture-positive patients treated with oral antibiotics were not at greater risk for unfavorable course of the disease than patients with negative blood culture result.

RESUMEN

OBJECTIVE: To identify demographic, clinical and laboratory characteristics of children with multiple erythema migrans (EM) in Slovenia. METHODS: We prospectively studied patients aged 15 years and less, examined at our department for multiple EM in 1996 and 1997. Demographic and clinical data were collected by means of a questionnaire. In addition, basic haematological and biochemical investigations, serologic testing, and Borrelia cerebrospinal fluid and blood cultures were performed. RESULTS: Ninety-five children (44 girls, 55 boys) aged 1 to 13.5 (median, 4.5) years fulfilled the inclusion criteria. A tick bite was recalled by 23%. The incubation period was 10.5 (range, 1 to 150) days, the duration of skin lesions before the initial examination 4 (range, 1 to 54) days, and the median number of skin lesions, 4.5 (range, 2 to 35). The initial disease was mild in 81% of patients. Local and systemic symptoms were reported by 11% and 30% of children, respectively. Clinical signs accompanying EM lesions were found in 42%. Cerebrospinal pleocytosis (predominantly lymphocytic) was seen in 18% of patients; none of them had frank clinical evidence of central nervous system involvement. Serum IgM and IgG antibodies were detected in 28% and 22% of children, respectively. In 3/79 (4%) patients, Borreliae were isolated from the blood and in 2/83 (2%) from the cerebrospinal fluid. In 2/81 (2%) children, borrelial IgG intrathecal antibody production was demonstrated. CONCLUSIONS: Multiple EM in Slovene children is a mild disease. However, some patients had an associated, usually asymptomatic, infection of the central nervous system.

RESUMEN

Involvement of the nervous system in Lyme borreliosis may occur with or without erythema migrans and it may present with a variety of neurological symptoms. In this study we analysed phenotypic and genotypic characteristics of 40 Borrelia strains isolated from cerebrospinal fluid (CSF) of 38 Slovenian patients with different clinical manifestations of Lyme borreliosis. In seven of the patients, Borreliae were also isolated from skin lesions. Species identification and plasmid profiles were determined by pulsed-field gel electrophoresis and protein profiles by SDS-PAGE. MluI digestion profiles of Borrelia burgdorferi sensu lato DNA showed that 25 (62.5%) isolates were B. garinii, 14 (35%) B. afzelii, and one (2.5%) B. burgdorferi sensu stricto. All strains, except one, possessed a large plasmid and a varying number of smaller plasmids. Three (7.5%) isolates exhibited an unusual plasmid profile, with a large plasmid dimer or three copies of the large plasmid. In protein analyses, all strains expressed OspA protein. OspB was present significantly more often in B. afzelii than B. garinii strains (p=0.0000), while OspC was more often present in B. garinii than B. afzelii strains (p=0.0052). In the seven patients with Borreliae isolated also from the skin, the CSF and skin isolates were identical, either B. garinii (six patients) or B. afzelii (one patient). Species and plasmid heterogeneity as well as antigen diversity could play a role in the pathogenesis of the infection. When combined with our own earlier data, the results suggest species-related organotropism.

RESUMEN

BACKGROUND: Little is known about the seroprevalence of ehrlichiosis in adults and much less about the same in children. METHODS: One hundred and forty-three healthy children and young adults (6-24 years of age, male to female ratio, 1:1) were assessed for the presence of antibodies to the agents of human granulocytic ehrlichiosis (HGE), human monocytic ehrlichiosis (HME), Borrelia burgdorferi sensu stricto (BB), and tick-borne encephalitis (TBE) virus in Slovenia, where tick-related infections are endemic. Antibodies to HGE and HME agents were assayed by indirect immunofluorescence, and antibodies to BB and TBE by enzyme-linked immunosorbent assay. A questionnaire about tick exposure was answered by all subjects. In the event of a positive result, a detailed interview was conducted. RESULTS: Of 143 study subjects, 22 (15.4%) had detectable antibodies to HGE agent, 22 (15.4%) were positive to BB, 18 (12.6%) were positive to TBE virus (12 of these were vaccinated) and 4 (2.8%) were positive to the HME agent. The history of persons seropositive to an HGE agent had been uneventful. CONCLUSIONS: Our study documents a high seroprevalence of HGE in children and young adults in Slovenia, similar to the seroprevalence of LB and higher than that of TBE and HME. Although the majority of these infections are probably asymptomatic or mild, active surveillance for acute HGE infections in children in areas endemic for tick-related infections is necessary.

RESUMEN

AIM: Clinical forms of Lyme disease in Gorski Kotar have occurred only sporadically, in contrast to the northwestern Croatia and the neighboring areas of Slovenia, which are well-known Lyme borreliosis endemic regions. Our aim was to assess the level of sero-prevalence of Borrelia burgdorferi sensu lato in a high-risk population of forestry workers in the mountainous region of Gorski Kotar, Croatia, and compare it with the sero-prevalence in the residents of that area and the neighboring littoral region. METHODS: A sero-epidemiological study was conducted on 520 healthy subjects, divided in 3 groups: the first group included 234 forestry workers, residents of Gorski Kotar, the second 100 residents of various professions in the same region, and the third 186 subjects of various professions from the neighboring littoral region. The sera were collected during the winters of two successive years, 1997 and 1998. Lyme borreliosis serology was performed by indirect immunofluorescence assay. Sera from 10 hunting dogs from Gorski Kotar were also analyzed. RESULTS: The IgG antibodies to B. burgdorferi sensu lato were found in 11 examinees (4.7%) from the group of forestry workers, in 3 (3%) from the second group, and in 5 (2.7%) from the third group. Four out of 10 dogs (40%) had IgG antibodies against B. burgdorferi. CONCLUSION: Our results show that the forest and mountainous area of Gorski Kotar, Croatia, has the characteristics of a low sero-prevalence area, in contrast to the endemic neighboring areas.

RESUMEN

Opsoclonus-myoclonus is a rare neurological syndrome affecting children and adults. In children it occurs as a parainfectious process or a paraneoplastic syndrome in association with neuroblastoma. Here we report it presenting as an unusual neurological manifestation of Lyme borreliosis. To our knowledge, this is the first report which describes recovery from this syndrome in a child.
