Individual cloacal swabs of mallards (Anas platyrhynchos) and of herring gulls (Larus argentatus), as well as samples of waterbird feces obtained in 2008 and 2009, were cultivated for Escherichia coli. Isolates of E. coli were tested for susceptibilities to 12 antimicrobial agents by the disk diffusion method. Moreover, the samples were subcultivated on(More)
AIMS To determine the presence of antibiotic-resistant faecal Escherichia coli in populations of wild mammals in the Czech Republic and Slovakia. METHODS AND RESULTS Rectal swabs or faeces collected during 2006-2008 from wild mammals were spread on MacConkey agar and MacConkey agar containing 2 mg l(-1) of cefotaxime. From plates with positive growth, one(More)
AIM To examine surface water from a pond in the northeastern part of the Czech Republic and young black-headed gulls (Larus ridibundus) nesting on the same pond for the presence of antibiotic-resistant Salmonella and Escherichia coli. METHODS AND RESULTS A total of 16% (n = 87) of water and 24% (n = 216) of gull samples yielded Salmonella. Salmonella(More)
AIMS To determine the occurrence of Shiga toxin-producing Escherichia coli (STEC) O157 and coliform bacteria isolates resistant to antimicrobial agents in dairy herds by examining milk filters and to analyse the influence of management factors and antibiotic use on antimicrobial resistance. METHODS AND RESULTS A total of 192 in-line milk filters were(More)
Antimicrobial resistance is a worldwide concern of public health. Unfortunately, resistant bacteria are spreading to all ecosystems, including the strictly protected ones. We investigated antimicrobial resistance in gastrointestinal Enterobacteriaceae of wild mammals and people living within Dzangha-Sangha Protected Areas, Central African Republic, with an(More)
AIMS To carry out an assessment of the occurrence of resistance to antimicrobials in Escherichia coli that has been isolated from young Black-headed Gulls in three nesting colonies. METHODS AND RESULTS A total of 257 isolates were tested for sensitivity to eight antibacterial substances by disk diffusion method. The polymerase chain reaction was used for(More)
Growing ornamental fish industry is associated with public health concerns including extensive antibiotic use accompanied by increasing antibiotic resistance. The aim of this study was to analyze Aeromonas isolates from imported tropical ornamental fish and coldwater koi carps bred in the Czech Republic to assess the potential risk of ornamental fish as a(More)
AIM The occurrence and epidemiology of extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli in the environment of turkey farms in the Czech Republic were studied. METHODS AND RESULTS Extended-spectrum beta-lactamase-producing E. coli isolates were found on 8 (20%) of 40 turkey farms surveyed. A total of 200 environmental smears were(More)
AIMS To determine the presence of antibiotic-resistant faecal Escherichia coli and Enterococcus spp. in feral pigeons (Columba livia forma domestica) in the Czech Republic. METHODS AND RESULTS Cloacal swabs of feral pigeons collected in the city of Brno in 2006 were cultivated for antibiotic-resistant E. coli. Resistance genes, class 1 and 2 integrons,(More)
The aim of the study was to compare the prevalence of extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli bovine isolates on a conventional dairy cattle farm with high consumption of parenteral and intramammary cephalosporins (farm A) and on an organic dairy farm with no cephalosporin use (farm B). ESBL-producing E. coli were isolated from(More)
