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 animals 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 catsserum samples from the first clinical evaluation.[...](AU)
