ABSTRACT
The seroprevalence study for leptospirosis in bovines and humans was realized in family holder farms along the Transamazon Highway. The prevalence of bovine leptospirosis was 97% [90.9 - 99.5%] of farms with at least one positive animal according to microscopic agglutination test for the leptospirosis diagnostic. In 61.2% of the tested herds, the serovar hardjo was the most common, followed by the serovar bratislava (9%) and the serovar shermani (4.5%). The serologic prevalence of leptospirosis in humans was 32.8% [23.4 - 43.5%] in family groups with at least one positive individual according to microscopic agglutination test for the leptospirosis diagnostic. In 9% of family groups, the serovar bratislava was the most common, while serovar hardjo and grippotyphosa accounted for 6% and 4.5%, respectively. The impact of these results is discussed in relation to animal production and public health. Suggestions have been proposed in order to improve the situation in the region.

Realizou-se o estudo da soroprevalência da leptospirose em bovinos e humanos especificamente em propriedades familiares na região de fronteira agrícola da rodovia Transamazônica, na Amazônia Oriental. A prevalência da leptospirose bovina foi 97% [90,9 99,5%] de propriedades com pelo menos um animal positivo na soroaglutinação microscópica para o diagnóstico da leptospirose. Em 61,2% dos rebanhos o sorotipo hardjo foi apontado como o mais provável, em 9% deles o sorotipo bratislava e em 4,5% o shermani. A prevalência sorológica da leptospirose humana foi 32,8% [23,4 43,5%] de núcleos familiares com pelo menos um indivíduo positivo na soroaglutinação microscópica para o diagnóstico da leptospirose. Em 9% dos núcleos familiares o sorotipo bratislava foi apontado como o mais provável, em 6% deles o sorotipo hardjo e em 4,5% o grippotyphosa. Foi discutido o impacto desses achados sobre a produção animal e saúde pública na região e feitas sugestões para minorar o problema.

A survey of 124 dogs for ticks was conducted from August to November 1998 in 68 small farms of Uruará municipality in Eastern Amazon-Brazil. We collected 55 ticks from 18 dogs (14.5%). Amblyomma oblongoguttatum Koch, Amblyomma ovale Koch, and Amblyomma cajennense (F.) were found on nine, six, and one dog, respectively. Fourteen small farms (20.5%) had at least one dog with ticks.

During a survey conducted from August to November 1998 to ticks associated with dogs in the rural area of Uruará, in the state of Para, Eastern Amazon region of Brazil, we collected one gynandromorph specimen out of 18 Amblyomma oblongoguttatum Koch specimens collected from dogs. It is a perfect bipartite gynandromorph, reported in this species for the first time.

Foram analisadas 33 amostras de fezes de cäes com diarréia (n=25) e sem diarréia (n=8), de variadas idades e raças, de ambos os sexos, a fim de se determinar a ocorrência de agentes virais considerados causadores da gastroenterite no cäo, suas possíveis associaçöes e a participaçäo no complexo gastroenterite canina, buscando relacionar a etiologia viral com o histórico de vacinaçäo, além do exame clínico dos animais. Utilizou-se microscopia eletrônica nas 33 amostras fecais e o teste ELISA em 71 amostras para detecçäo de antígeno de rotavírus e adenovírus. Partículas virais foram detectadas em 75,8 por cento (25/33) do total de amostras diarréicas ou näo, examinadas à microscopia eletrônica. Em 44 por cento dos espécimes positivos para vírus (11/25), o vírus-like tipo 1 foi o mais detectado nas amostras fecais, seguido por parvovírus (24 por cento). A ocorrência de diarréia com sangue esteve associada a 90,9 por cento dos agentes detectados, variando em freqüência de 25 por cento a 100 por cento dos casos
