PREVALÊNCIA DE PARASITAS GASTROINTESTINAIS EM OVINOS CRIADOS NO MUNICÍPIO DE POÇO VERDE, SERGIPE

The objective of this work was to identify the main gastrointestinal parasites present in sheep herds in the municipality of Poço Verde, Sergipe. For that, 150 animals, distributed in 7 rural properties, were submitted to the FAMACHA® test to assess the degree of anemia. After detecting anemia, feces were collected for coprological tests. The samples were processed by the technique of counting eggs per gram of feces (OPG). Associated with this, feces culture was carried out, which allowed the identification of the genera of infective larvae. A high frequency of FAMACHA® grade 1 and 2 was observed, corresponding to 75.33% of the herds analyzed. On the other hand, 24.67% fit the classification of FAMACHA® 3 and 4, indicating infection by hematophagous parasites. OPG analysis revealed the presence of the genera Trichostrongylus spp. (45%), Strongylus spp. (23%), oocysts of Eimeria spp. (18%) and Moniezia spp. (14%). Regarding egg count and degree of infection, 60% of the animals had a mild degree, 27% moderate and 13% high. In coproculture, Oesophagostomum spp. was the most frequent genus of parasites, with an incidence of 31% among infective larvae (L3), followed by Chabertia spp. (23%), Cooperia spp. (15%), Namatodirus spp. (8%), Trichostrongylus spp. (8%) and Haemochus spp. (7%), with the presence of hyphae (8%). The joint application of the different methods is necessary to prevent parasitic infections and the development of parasitic resistance.O objetivo deste trabalho foi realizar a identificação dos principais parasitas gastrintestinais presentes em rebanhos ovinos do município de Poço Verde, Sergipe.

Anticorpos anti-Leptospira spp. em animais selvagens do zoológico municipal de Ribeirão Preto, Estado de São Paulo, Brasil

Leptospirosis may affect all domestic and wild animals as well as human beings. Some serological studies have shown the involvement of wild species in the epidemiology of the disease. Once captive wild animals are not much studied, especially in Brazil, the present study aimed to detect anti- Leptospira spp. antibodies in animals from Ribeirão Preto city zoo, in São Paulo state, Brazil. Blood samples were collected from captive birds, fish, reptiles and mammals, sinanthropics and free-living animals and also from employees between March and October, 2006. Four hundred and three blood samples were obtained, 388 animals' samples (110 reptiles, 143 birds, 110 mammals and 25 fish) and 15 humans'. The sera were analysed by Microscopic Agglutination Test using 22 serovars from pathological leptospiras and two from non-pathological serovars. Among the animal samples, 339 were from captive animals, and 49 from free-living ones, captured with traps inside the zoo. One hundred and three (103/388 = 26.5%) samples reacted to leptospirosis, ninety-two (92/339 = 27.1%) samples were from captive animals and eleven (11/49 = 22.4%) from free-living ones. All humans' samples were negative. Serological titles varied from 40 to 5.120, with predominance of titles between 40 and 80 and the most frequent serovars were Patoc, Andamana, Canicola, Icterohaemorrhagiae and Panama
