Abstract

A survey of the bacterial flora in the genital tract of cattle with emphasis on Campylobacter fetus was carried out in 48 bulls and 98 cows from herds in Selangor and Negeri Sembilan. Cervical samples were collected with sterile swabs while preputial scrapings were collected using pipettes. Samples were cultured into blood agar and selective medium. of Brucella broth and brain heart infusion agar with and without antibiotics. The bacteria isolated were identified while growths in the selective media: were checked for c.fetus. The major organisms isolated from the animals were Staphylococcus epoidermidis (61.8%), corynebacteriwn (45.1%), micrococcus (41.7%) and Staphylococcus aureus (34.0%). The major bacteria common in the fertile and infertile animals were Staphylococcus epidermidis, corynebacteriwn, bacillus and micrococcus. staphylococcus epidermidis, was predominant in animals at UPM and at MARDI, while E.coli and micrococcus was predominant in Ijok and Pantai respectively. Noc.fetus was seen from direct smears and none were isolated from the selective media. However no conclusive findings could be drawn from the selective cultures since pure c.fetus samples also did not grow in the selective media. The results suggest that a range of bacterial types occur as a normal population in the genital tract of cattle. The major bacteria isolated in the female animals in the present study can cause endo-metritis under favorable conditions but their overall signific1nce in infertility need to be further studied.
