RESUMO
For the first time, it was identified a mite in a three-year-old male ostrich that had lost feathers and showed skin irritation. The animal belonged to a flock of 50 birds, located in Baixada Fluminense, in Rio de Janeiro State. After they were fixed in 70 percent alcohol, clarifyed in lactophenol and mounted in Canada balsam, the mites were identified in the laboratory. They belonged to the Pterolichidae family and Struthioperolichus sculpturatus species (Hirst). The ostrich was treated by ivermectin in dose of 200µg/kg of body weight, with recovery and disappearance of the clinical symptoms. The occurrence of mite infestation by the described species in ostrich should be monitored by professionals and farmers, as they cause fall of feathers and economic losses.(AU)

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.

RESUMO
Serum samples from 77 animals belonging to 38 species and 19 families in Rio de Janeiro Zoo, Brazil were tested for antibodies against serovars of Leptospira interrogans by microscopic agglutination test. Antibodies were detected in serum samples of 37.7% of all animals belonging to 10 families. Seropositivity was more common in the Carnivora Canidae (7/9), Procyonidae (5/9) and the Edentata Myrmecophagidae (5/9). Icterohaemorrhagiae was the most common serogroup. Seropositivity was less common in primates.

Estudou-se a presença de anticorpos para o vírus da influenza aviária, subtipos H1N1 e H3N2, por meio da técnica de inibiçäo da hemaglutinaçäo no plasma de 225 aves da Fundaçäo RIO-ZOO, do Bwana Park e de pequenas criaçöes do Estado do Rio de Janeiro. Entre as aves estudadas 60 (26,6 por cento) foram soropositivas, sendo 22 (9,8 por cento) para o subtipo H1N1, 28 (12,4 por cento) para o subtipo H3N2 e 10 (4,4 por cento) para os dois subtipos. Esses resultados indicam a ocorrência dos subtipos do vírus da influenza aviária investigados no Rio de Janeiro e apontam para o risco potencial de sua transmissäo para a avicultura industrial e para pessoas

The presence of antibodies to the avian influenza virus subtypes H1N1 and H3N2, was studied through the technique of hemagglutination inhibition in the plasma of 225 birds of RIO-ZOO Foundation, Bwana Park and of small flocks of the Rio de Janeiro State. Among the studied birds, 60 (26.6%) were seropositives, being 22 (9.8%) for the subtype H1N1, 28 (12.4%) for the subtype H3N2 and 10 (4.4%) for both subtypes. These results indicate the occurrence of these avian influenza virus subtypes in Rio de Janeiro and point out the potential risk of their transmission for the industrial poultry and humans.
