Isolation and Antimicrobial Testing of Aeromonas spp., Citrobacter spp., Cronobacter spp., Enterobacter spp., Escherichia spp., Klebsiella spp., and Trabulsiella spp. from the Gallbladder of Pigs
Journal Title: Polish Journal of Microbiology - Year 2015, Vol 64, Issue 2
Abstract
The presence of Gram-negative bacteria species, other than [i]Salmonella[/i] spp., in the gallbladder of pigs was examined. Isolated Gram-negative bacteria were assigned to species using the MicrogenTM GnA+B-ID Systems. Of the 64 isolated strains 43 were identified as [i]Escherichia coli[/i], seven as [i]Enterobacter[/i] spp., three each as[i] Klebsiella[/i] spp., [i]Citrobacter freundii[/i], [i]Aeromonas hydrophila[/i] and [i]Cronobacter sakazakii[/i] and one each as [i]Escherichia fergusonii[/i] and [i]Trabulsiella guamensis[/i]. Their antibiograms showed very high resistance to ampicillin, amoxicillin, tetracycline, chloramphenicol and sulfamethoxazole/trimethoprim. It was concluded that the pigs’ gallbladder is a reservoir of potentially pathogenic Gram-negative bacteria for pork consumers.
