Abstract

A survey of Campylobacter in 177 faecal samples from pigs (110), dogs (62) and cats (5) was carried out. Campylobacters were isolated from 57 samples (32.2%), being 4 strains (3 C. jejuni and 1 C. coli) resistant to nalidixic acid (7.1%). All the nalidixic acid resistant strains presented cross resistance to ciprofloxacin, norfloxacin and enoxacin by the agar diffusion method and by the quantitative method of Wilkins and Thiel (MIC? 40 ?g/ml). These findings suggest that in our media, it is possible to isolate quinolone resistant strains of Campylobacter which represent a diagnostic problem for the laboratory and an epidemiological and therapeutic problem for clinical practice.
