Incidence of Feline Leukemia and Immunodeficiency virus in catsamongst indigenous Indians in Brazil.

摘要

Toxoplasma gondii oocysts excreted by cats, and poor sanitation and hygiene is thought to be responsible for a high incidence of toxoplasmosis in some indigenous Brazilians. Feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) may reactivate latent toxoplasmosis infections; the incidence of FeLv and FIV in 43 cats in indigenous settlements was evaluated. Results showed that 37 cats appeared normal, 4 had lesions suggestive of squamous cell carcinoma, 2 appeared weak, but none were positive to ELISA. The conflicting results may be due to age, and/or antigen and antibody being absent or below detection levels.
