Toxoplasmosis is a parasitic disease caused by the protozoan Toxoplasma gondii, characterized by a clinical or subclinical infection attributed mainly to the isolate of the parasite responsible for the infection. Although domestic felines are considered the only urban hosts of this parasite and, consequently, the animals responsible for perpetuating T. gondii cycle in this environment, there is still a lack of information regarding the potential of different strains/isolates of this parasite and appearance of clinical signs during infection in domestic felines. In this context, the objective of the present study was to evaluate the clinical, parasitological, and serological characteristics of toxoplasmosis in felines infected with T. gondii isolates type I (RH strain) and III (P strain). Twelve healthy and serologically negative felines were selected for T. gondii (IgG titer < 16). These animals were divided into three experimental groups, GI: (P1, P2, P3, and P4) inoculated with 600 cysts of T. gondii (P strain), GII: (RH1, RH2, RH3, and RH4) inoculated with 2 × 105 tachyzoites (RH strain), and GIII: (C1, C2, C3, and C4) uninoculated. From the seventh day before (day ?7) to the 70th day after inoculation (DAI), the animals were observed daily to verify the occurrence of alterations in the digestive, nervous, locomotor, cardiorespiratory, and urinary systems, as well as skin and appendages. The clinical signs most observed in felines inoculated with T. gondii were apathy, hyporexia, shivering, nasal secretion, ocular secretion, and diarrhea. The results obtained in this study allow inferring that T. gondii isolate type I (RH strain) was more pathogenic to feline species than isolate type III (P strain), although both showed clinical symptomatology in all infected animals.Metrics

A revista tem o direito de fazer, no documento original, alterações referentes às normas lingüísticas, ortografia e gramática, com o objetivo de garantir as normas padrão do idioma e a credibilidade da revista. No entanto, respeitará o estilo de escrita dos autores.
Quando necessário, alterações conceituais, correções ou sugestões serão encaminhadas aos autores. Nesses casos, o manuscrito deve ser submetido a uma nova avaliação após revisão.
A responsabilidade pelas opiniões expressas nos manuscritos é inteiramente dos autores.
