ABSTRACT
Faeces or rectal swabs from 689 diarrhoeic and non-diarrhoeic animals were cultured for thermophilic campylobacters and their antibiograms were determined. Three hundred and fifteen (45.7 percent) samples were positive for Campylobacter. Piglets had the highest prevalence, 79.3 percent (233/294) and lambs, the lowest with 17.9 percent (15/84) being positive. The difference was statistically significant (P < or = 0.01; chi 2). In calves, 20.5 (60/293) and in kids 38.9 percent (7/18) were positive for campylobacters. The prevalence of infection was not significantly (P > or = 0.05; chi 2) different between diarrhoeic (46.1 percent) and non-diarrhoeic (45.1 percent) animals nor between male (47.5 percent) and female (43.8 percent). The frequency of isolation of campylobacters harvested from semi-intensively managed animals (75.4 percent) was, however, significantly higher (P < or = 0.001; chi 2) than from intensively or extensively managed animals. Overall, C. coli strains (32.8 percent) were more frequently isolated than C. jejuni strains (12.9 percent) and the difference was significant (P < or = 0.001; chi 2). Biotype I accounted for 67.3 percent (152/226) of C. coli and 64.0 percent (57/89) of C. jejuni strains isolated. A total of 245 (77.8 percent) strains of Campylobacter exhibited resistance to one or more antibiotics and was highest to streptomycin (76.5 percent), kanamycin (28.6 percent) and neomycin (26.7 percent). It was concluded that Campylobacter infections were widespread in livestock in Trinidad, particularly C. coli in piglets. (AU)
