RESUMO

Dada la importancia de la correcta validación clínica de los aislamientos de Streptococcus bovis, nos planteamos la revisión de su presencia en muestras de orina con el objetivo de conocer su frecuencia relativa y su patrón de sensibilidad antibiótica. Se revisó retrospectivamente la sensibilidad a los antibióticos de 91 aislados de S. bovis recuperados de muestras de orina durante un período de 4 años (2012-2015). La media de la edad de los pacientes fue de 55 años y en su mayoría fueron mujeres (81%). El 37,4% eran pacientes hospitalizados con enfermedades urológicas (61%). La sensibilidad a penicilina, vancomicina y teicoplanina fue del 97,8%. Aunque S. bovis puede ser poco común en los aislamientos de orina, su presencia en sujetos con enfermedades de base justifica la realización de estudios de patogenicidad que demuestren la verdadera capacidad de producir enfermedad de este grupo de bacterias.


Given the relevance of proper clinical validation of Streptococcus bovis, we here consider revising its presence in urine samples in order to determine its relative frequency and the pattern of antibiotic susceptibility. The susceptibility to antibiotics of 91 isolates of S. bovis from urine samples was retrospectively reviewed over a period of 4 years (2012-2015). The mean age of patients was 55 years, 81% of whom were women and 37.4% were hospitalized patients suffering from urological diseases (61%). Susceptibility to penicillin, vancomycin and teicoplanin was 97.8%. Due to the fact that S. bovis can be infrequent in urine isolates and given its presence in patients suffering from urological diseases, further pathogenic studies, showing the true ability of this group of bacteria to produce disease, are required.

RESUMO

Granada virus (GRV), a new phlebovirus within the Naples serocomplex, has been recently described in phlebotomine sandflies from Spain. The presence of anti-GRV immunoglobulin G (IgG) antibodies was investigated by indirect fluorescence assay (IFA) and neutralization test (NT) in 920 serum samples from the Granada population. By IFA, an overall GRV seroprevalence of 15.8% (N = 145) was observed, significantly increasing up to 65 years. NT was positive in 18% of anti-GRV IFA-positive samples. IgG antibodies against Toscana virus (TOSV), a hyperendemic phlebovirus within Granada province, were detected in 40% of anti-GRV-positive cases. Anti-GRV IgM antibodies were detected in 36 (6.6%) of 547 acute-phase serum samples from individuals with febrile illness, exanthema, and/or acute respiratory infection. All positives were anti-TOSV IgM-negative. GRV may infect humans, with most cases being asymptomatic. The codetection of anti-GRV and anti-TOSV IgG antibodies could be attributable to cross-reactivity or exposure to the same transmission vector.
