ABSTRACT
To evaluate the anthelmintic effect of Musa spp. leaves, 12 animals were artificially infected with Haemonchus contortus, and another 12 animals were infected with Trichostrongylus colubriformis. Then, both treatment groups were offered 400 g of dried ground banana plant leaves, and the control animals were offered only 1000 g of coast cross hay. During the trials, the animals received weekly physical examinations. The methods used to evaluate the efficiency of this treatment were packed cell volume, total plasma protein and faecal egg counts, and egg hatchability tests were performed on days -2, +3, +6, +9, +13 and +15. Coproculture tests were performed on day -2 to confirm monospecific infections. In the FEC and EHT, a statistically significant difference (0.04, 0.005; p < 0.05) was noted for T. colubriformis. There were no statistically significant differences (p > 0.05) for Haemochus contortus group in all tests. Our results confirmed previous findings suggesting that dried ground banana plant leaves possess anthelmintic activity.

O objetivo deste estudo foi avaliar a ocorrência da infecção pelo vírus Maedi-Visna em ovinos criados nas microrregiões de Botucatu, Campinas, Piedade e São Paulo do Estado de São Paulo. As amostras de soro sanguíneo foram colhidas de 226 ovinos e foi realizada a técnica de imunodifusão em gel de ágar para a detecção de anticorpos antivírus Maedi-Visna e verificou-se que nenhuma das amostras testadas foi sororeagente. Dessa forma, faz-se necessário um estudo mais amplo no estado, a fim de se confirmar a baixa ocorrência e importância da enfermidade no estado.
Survey for antibodies against maedi-visna virus in sheep in the regions of Botucatu, Campinas, São Paulo and Piedade, state of São Paulo, Brazil. The purpose of the study was to evaluate the occurrence of infection with maedi-visna virus in sheep raised in the regions of Botucatu, Campinas, Piedade and São Paulo, state of São Paulo, Brazil, that showed symptoms of the disease. Blood serum samples collected from 226 sheep were submitted to the agar gel immunodiffusion technique for detection of antibodies against maedi-visna virus, and none of the samples tested was serum reactive. In conclusion, the maedi-visna virus has low frequency in animals raised in the regions studied.

Cães capturados nas ruas de quatro municípios do estado de São Paulo foram examinados para estudar a prevalência de Hepatozoon canis. Dos 222 animais, 13 (5.9 por cento) encontravam-se infectados. Exames hematológicos realizados em nove animais evidenciaram três com anemia e um com leucocitose. A única alteração encontrada nos exames bioquímicos foi hiperglobulinemia.
