Leptospirosis in a giant anteater (Myrmecophaga tridactyla, Linnaeus, 1758) in Rio de Janeiro Zoo, Brazil

An adult female giant anteater (Myrmecophaga tridactyla) presented leptospirosis in Rio de Janeiro Zoo. Serum samples werecollected and agglutinins anti-Leptospira interrogans serovar icterohaemorrhagiae were evidenced. Hemogram and biochemicalanalysis were compatible with the disease. Therapy was instituted with an association of Penicillin, Streptomycin andDihydrostreptomycin. No toxic effects of antibiotic association could be noticed and this therapy was considered adequate totreat giant anteater leptospirosis. We suggest giant anteater immunisation against leptospirosis to be implemented in riskareas and further investigation on the vaccination efficacy in this species.
