CAMPYLOBACTER-JEJUNI IN 2 GROUPS OF HENS AND STUDY OF ANTIMICROBIAL SUSCEPTIBILITY

Campylobacter jejuni is a leading agent of diarrhoea being poultry one of its most important reservoirs. Bearing in mind the relationship be tween poultry and infection, the prevalence of C. jejuni was determine d in hens from domestic farms and from one industrial farm. C. jejuni was isolated in 58.7% and 22.4%, respectively (p < 0.001). Furthermore MIC(50) and MIC(90) to 11 antimicrobial drugs were determined, being the strains isolated from the industrial farm more sensitive than thos e isolated from domestic farms. Strains isolated from both groups of h ens were resistant to azthreonam (MIC greater than or equal to 128 mu g/ml).
