Cracids are wildlife Galliformes which inhabits the America’s tropical forests. Fifty one cloacal swabs were collected from 10 different species of captive cracids from the Rio Grande do Sul State during 2007. The cloacal swab samples were submitted to bacterial isolation, identification and, subsequently; antimicrobial susceptibility testing. Ninety three bacterial isolates were obtained from the cracid population examined. The most prevalent among the isolates were Escherichia coli, and bacteria from the Staphylococcus and Streptococcus genera. All samples tested in this study were negative for Salmonella spp. The antimicrobial susceptibility tests showed that none of the 93 strains presented resistance to the antimicrobial imipinem. In addition, the lower percentages of resistance were observed against cloranfenicol and ciprofloxacine. The bacteria genus and species with the highest percentage of resistance to the different antimicrobials examined were E. coli, Serratia marcescens, Staphylococcus spp. and Streptococcus spp. In conclusion, the data presented in this article demonstrate that the cloacal microbiota of the reported cracid population is composed of several bacterial genera and species and multi-drug resistance may be a problem for the future, since some strains showed elevated percentage of resistance against several different antimicrobials. |
