Zusammenfassung: | Thirty nine breeding bulls from dairy farms (n=9) and beef farms (n=30) located in Medio Paraiba region at Rio de Janeiro--Brazil state were investigated for the presence of Campylobacter fetus and Tritrichomonas foetus. For Campylobacter investigation, smegma samples were examined by culture and prepucial washings were examined by direct immunofluorescence technique (DIF). The prepucial washings were also examined for Tritrichomonas foetus presence by direct examination. C. fetus was identified in 14 samples (35.9 %) by DIF technique and C. fetus subspecies venerealis was isolated from four samples (10.3%). T. foetus was not detected in bull samples. The high frequency of C. fetus observed in bull samples suggests the occurrence of campylobacteriosis among herds which have reproductive problems at the Medio Paraiba region. Key words: Campylobacter fetus, Tritrichomonas foetus, prepucial mucous, bulls. Trinta e nove touros provenientes de propriedades de pecuaria leiteira (n=9) e de pecuaria de corte (n=30), situadas na regiao do Medio Paraiba, Rio de Janeiro (RJ), foram investigados para a presenca de Campylobacter fetus e Tritrichomonas foetus. Para a pesquisa de Campylobacter, amostras de esmegma foram coletadas e submetidas a tecnica de cultivo e isolamento e amostras de lavado prepucial ao teste de Imunofluorescencia Direta (IFD). Para a pesquisa de Tritrichomonas, foi utilizada a tecnica de exame direto a partir de lavado prepucial. Foi observada a presenca de C. fetus em 14 amostras (35,9%), por meio da IFD, e o isolamento de C. fetus, subespecie venerealis, foi obtido a partir de quatro amostras (10,3%). T. foetus nao foi identificado nas amostras investigadas. A alta frequencia de C. fetus observada nos animais investigados sugere a presenca da campilobacteriose na regiao do Medio Paraiba, em rebanhos com problemas reprodutivos. Palavras-chave: Campylobacter fetus, Tritrichomonas foetus, mucosa prepucial, touros. |
