Evaluation of Antimicrobial Resistance Using Indicator Bacteria Isolated From Pigs and Poultry in Chile
نویسنده
چکیده
Antimicrobial resistance is a phenomenon of increasing importance, as demonstrated by the emergence of different international antimicrobial resistance surveillance programs. The aim of this research was to perform an antimicrobial resistance evaluation in indicator bacteria isolated from pigs and poultry in Chile. One hundred E s c h e r i c h i a c o l i and 80 E n t e r o c o c c u s species strains were isolated from fecal samples from pigs, and 99 E coli and 80 Enterococcus s p e c i e s strains were isolated from cloacal samples from poultry. The samples were analyzed using the dilution plates method. E coli strains showed a high percentage of antimicrobial resistance (>87%) in both animal species, with resistance to tetracycline and streptomycin being the most commonly Intern J Appl Res Vet Med • Vol. 3, No. 2, 2005 Financial support for this study was provided by Fondecyt 1030857, the Chilean national fund for scientific and technological development.

Enterococci are Gram-positive facultative anaerobic bacteria commonly found in the gastrointestinal tract of the mammals and birds. These cocci are isolated from urinary tract infections, bacteremia, endocarditis, and burn wounds in humans. The evolution of antibiotic-resistant enterococci raised a problem due to the possibility of the transmission of these organisms between poultry and human. ...
