Lucas, SRR, Valvassoura, TA, Pinheiro, SR Incidence of Feline Leukemia and Immunodeficiency virus in cats amongst indigenous Indians in Brazil.Onl J Vet Res., 22 (12):1111-1118, 2018.  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.


KEY WORDS: feline leukemia virus, feline immunodeficiency virus, cats, indigenous, Brazil.
