| phenotypic and genotypic characteristics of antimicrobial resistant escherichia coli isolated from symbovine flies, cattle and sympatric insectivorous house martins from a farm in the czech republic (2006-2007). | the prevalence of antimicrobial resistant escherichia coli was tested in symbovine flies and sympatric house martins (delichon urbica) at a dairy farm. antimicrobial resistant e. coli was detected in 89% (n=147) of isolates from flies within a calf barn. isolates with the same antimicrobial resistance phenotypes, genes, and pulsotypes were found between both fly and calf e. coli isolates, suggesting that the calves were the initial source of the antimicrobial resistant strains in fly isolates. s ... | 2010 | 20350731 |
