RESUMO

Background: Sporotrichosis is an endemic zoonosis in the metropolitan region of Rio de Janeiro caused by fungi included in the Sporothrix complex, in which cats are the main source of infection for humans and animals. Coinfections in cats with sporotrichosis from this region, their risk factors and how they affect the treatment outcome in these animals are little known. The objectives of this study were to determine the coinfections of Sporothrix spp. with Toxoplasma gondii, Feline Immunodeficiency Virus (FIV) and Feline Leukemia Virus (FeLV) and to correlate these infections with risk factors and the outcome of sporotrichosis treatment in cats from an endemic area of sporotrichosis in Rio de Janeiro, Brazil.Materials, Methods & Results: It was conducted a cohort study involving 213 cats with definitive diagnosis of sporotrichosis from the metropolitan area of Rio de Janeiro and assisted in the Laboratory of Clinical Research on Dermatozoonosis in Domestic Animals (LAPCLIN-DERMZOO)/Evandro Chagas National Institute of Infectious Diseases (INI)/Oswaldo Cruz Foundation (Fiocruz), in Rio de Janeiro, RJ, Brazil, from November 2007 until February 2011. These animals were monthly evaluated due to sporotrichosis treatment until their sporotrichosis treatment outcomes. In every clinical evaluation, 5 mL of blood were collected in order to obtain the serum, which was stored at -20ºC. Information from the animal’s medical records have also been collected, such as sex, eating habits, living with other cats, access to the streets, castration, age and the outcome of sporotrichosis treatment. Serological follow-up of anti-T. gondii antibodies were performed through indirect hemagglutination assay (IHA) and indirect fluorescent antibody test (IFAT) in all clinical evaluations. The FIV and FeLV antibody detection were made through a rapid immunoassay using the cats’serum samples from the first clinical evaluation.[...]

RESUMO

INTRODUCTION: Sporotrichosis is a mycosis affecting both humans and animals. Within the context of the ongoing sporotrichosis epidemic in the State of Rio de Janeiro, Brazil, sick cats plays an important role in the zoonotic transmission. The aim of this study was to update the number of feline cases diagnosed at the Fundação Oswaldo Cruz (2005-2011). METHODS: The medical records of the cats followed were reviewed; the inclusion criterion was the isolation of Sporothrix spp. in culture. RESULTS: In total, 2,301 feline cases were identified. CONCLUSIONS: These results should alert sanitary authorities to the difficulties associated with sporotrichosis control.

RESUMO

A doença da arranhadura do gato é uma zoonose causada por bactérias do gênero Bartonella. O gato atua como reservatório de Bartonella henselae e a transmissão ao humano ocorre através da arranhadura ou mordedura. A esporotricose, causada por fungos do complexo Sporothrix, é transmitida aos humanos através da implantação traumática deste microrganismo no tecido subcutâneo. Os gatos com esporotricose apresentam lesões cutâneas ulceradas com elevada carga parasitária e têm importante papel na transmissão. Nos últimos 14 anos foram diagnosticados mais de 3.000 casos de esporotricose felina no IPEC/FIOCRUZ. Com o objetivo de estudar a soroprevalência de infecção por Bartonella spp. em gatos com esporotricose, 112 amostras de soro foram submetidas ao teste de imunofluorescência indireta utilizando o kit B. henselae IFA IgG (Bion®, USA). Além disso, foi realizada a pesquisa de anticorpos anti-vírus da leucemia felina (FeLV) e antígenos do vírus da imunodeficiência felina (FIV) utilizando kit comercial Snap Combo FIV-FeLV (Idexx®, USA). Um grupo composto por 77 amostras de soro de gatos sem lesões cutâneas aparentes também foi incluído no estudo. No grupo de gatos com esporotricose, 93 eram machos, a idade mediana foi 22 meses e oito (7,1 por cento) foram positivos para FIV e 15 (13,4 por cento) para FeLVNo grupo sem lesões cutâneas, 36 eram machos, a idade mediana foi 48 meses, e dez (13,0 por cento) gatos foram positivos para FIV e oito (10,4 por cento) para FeLV. Dos 112 gatos com esporotricose e dos 77 sem leões cutâneas, 72 (64,3 por cento) e 35 (45,5 por cento), respectivamente, foram reativos ao teste de imunofluorescência para Bartonella spp. Não houve associação entre as variáveis faixa etária, sexo, status sorológico para FIV/FeLV e a presença de anticorpos anti-Bartonella spp. Os resultados obtidos sugerem que a população de gatos com esporotricose deste estudo pode ser considerada uma potencial fonte de infecção humana também para Bartonella spp...

Cat scratch disease is a zoonosis caused by species of genus Bartonella. Cats are the mainreservoir of Bartonella henselae. Transmission of these bacteria to humans occurs throughbites or scratches of infected cats. Sporotrichosis, caused by fungus of Sporothrix complex,is transmitted by traumatic inoculation of soil, plants and organic matter contaminated withthe fungus. Cats are important in zoonotic transmission because of the large amount ofyeast cells in the lesions. In the last 14 years were diagnosed more than 3.000 cases offeline sporotrichosis in IPEC/FIOCRUZ. The main objective of this study was toinvestigate the prevalence of infection by Bartonella spp. in cats with sporotrichosis. Serumsamples from 112 domestic cats were analyzed by indirect immunofluorescence test assay(IFA) using the commercial kit B. henselae IFA IgG (Bion®, USA). In addition, it wasdetected the presence of antibodies to feline leukemia vírus (FeLV) and antigens of felineimmunodeficiency virus (FIV) using the commercial kit Snap Combo FIV-FeLV (Idexx®,USA). One group of 77 serum samples from cats with no apparent skin lesions was alsoincluded in the study. In the group of animals with sporotrichosis, 93 were males, medianage was 22 months, and eight (7.1 percent) were positive for FIV, 15 (13.4 percent) were positive forFeLV. In the group of animals without skin lesions 36 were males, median age was 48months, and ten (13.0 percent) were positive for FIV, eight (10.4 percent) were positive for FeLV. Ofthe 112 cats with sporotrichosis and 77 cats without skin lesions, 72 (64.3 percent) e 35 (45.5 percent),respectively, were reactive to IFA. There was no association between age, sex, FIV/FeLVand the presence of antibodies to Bartonella spp. The results suggest that the studypopulation can be considered a potential source of human infection by both zoonosis...
