ABSTRACT
ABSTRACT: This study was carried out to examine the drug-resistant characteristics of airborne Enterococcus faecalis (E. faecalis) isolated from an enclosed-type chicken shed in Qingdao, China. An anderden-6 stage air sampler was employed to collect air samples inside the chicken shed continuously for 1 week. From these sampling media, we identified 80 nonrepetitive airborne E. faecalis isolates. The resistance of the airborne E. faecalis isolates to 7 commonly prescribed antibiotics was then analyzed. The resistance rates of isolates to 7 antibiotics (gentamicin, streptomycin, tetracycline, erythromycin, penicillin, amoxicillin, and vancomycin) were respectively 85% (68/80), 82.5% (66/80), 81.3% (65/80), 62.5% (50/80), 60% (48/80), 56.3% (45/80), and 10.0% (8/80). These results showed that the resistance airborne E. faecalis of chicken house is of high prevalence.
