Description
| - Byla vyhodnocena antibiotická rezistence celkem u 126 izolátů salmonel z prasat zařazených do 13 sérotypů (Typhimurium, Derby, Infantis, Enteritidis, Agona, Kaapstad, London, Montevideo, Bredeney, Give, Oritamerin, Schwarzengrund and Tennessee). Rezistence k jednomu a více antibiotikům byla zjištěna u 64 izolátů (59,8 %), zařazených do sedmi sérotypů z nichž nejčastěji se vyskytoval Typhimurium (n=54). Kmeny S. typhimurium byly nejčastěji rezistentní ke streptomycinu (91.5 %), sulfonamidům (88.1 %), ampicilinu (86.4 %), tetracyklinu (84.7 %) a chloramfenikolu (83.0 %) - fenotyp ACSSuT. U všech kmenů tohoto fenotypu (n=27) byl metodou PCR detekován gen pro integrázu (Int1) a geny rezsitence blaPSE-1, floR, aadA2, sul1 a tetG. U některých těchto kmenů byly zjištěny ještě přídatné rezsitence k amoxycilinu/kyselině klavulanové , sufametoxazolu/trimetoprimu, kyselině nalidixové a enrofloxacinu. (cs)
- A total of 126 Salmonella spp. isolates from pigs belonging to 13 serotypes (Typhimurium, Derby, Infantis, Enteritidis, Agona, Kaapstad, London, Montevideo, Bredeney, Give, Oritamerin, Schwarzengrund and Tennessee) were tested for sensitivity to 14 antibiotics. Resistance to 1 and more antibiotics was demonstrated in 64 isolates (59.8 %) classsified into seven serotypes with the most frequent Typhimurium (n=54). S. typhimurium strains were most often resistant to streptomycin (91.5 %), sulphonamides (88.1 %), ampicillin (86.4 %), tetracycline (84.7 %) and chloramphenicol (83.0 %) displaying the ACSSuT phenotype. In all strains of this phenotype (n=27), gene for integrase (int1) and resistance genes blaPSE-1, floR, aadA2, sul1 and tetG were detected by PCRs. In some of the strains, additional resistance to amoxycillin/clavulanic acid, sulphamethoxazole/trimethoprim, nalidixic acid and enrofloxacin was found.
