Description
| - Na mléčných farmách v Šumicích a troskotovicích byly odebrány rektální vzorky z telat, krav, mladých býků a vrabce domácího (Passer domesticus). U bakterie Escherichia coli, izolované z těchto vzorků, byla testována rezistence vůči 12 vybraným antibiotikům. Rezistence byla zjištěna u 40%(n = 183), 3%(n = 95), 0%(n = 33), and 9%(n = 54) E. coli izolátů z telat, krav, býků a vrabců. U izolátů z telat byli identifikovány geny rezistence: tetA, tetB (u izolátů rezistentních vůči tetracyklinu), blaTEM (beta-laktamázy), strA, aadA (streptomycin), sul1, sul2 (sulfonamidy), cat, floR (chloramfenikol).

- Rectal smears of calves, cows and young bulls, as well as cloacal smears of house sparrows(Passer domesticus), from farms at the villages of Šumice and Troskotovice, Czech Republic, were examined for E. coli resistant to 12 antimicrobials. The resistant isolates were tested for antimicrobial-resistance genes and integrons. Totals of 40%(n = 183), 3%(n = 95), 0%(n = 33), and 9%(n = 54) of Escherichia coli isolates from calves, cows, young bulls and house sparrows, respectively, were antimicrobial resistant. The following genes were identified in cattle E. coli isolates: tetA, tetB (isolates resistant to tetracycline), blaTEM (beta-lactams), strA, aadA (streptomycin), sul1, sul2 (sulphonamides), and cat, floR (chloramphenicol). Seven of 16 antimicrobial-resistant calf isolates from the Šumice farm possessed class 1 integrons with the aadA1 gene cassette integrated,1kbin size.On the Troskotovice farm, eightof57 antimicrobial-resistant calf isolates possessed class1integrons.
