Description
| - Mezi lety 2005 a 2007 byl sledován výskyt Y. enterocolitica u prasat, a to zvláště sérotypů O:3 a O:9, patogenních pro člověka. Celkem bylo ve 1 706 vzorcích z jazyka, povrchu kůže, povrchu kůže v okolí rekta, z rektálního obsahu a z tonzil izolováno 76 patogenních kmenů Y. enterocolitica. Y. enterocolitica byla nalezena nejčastěji na tonzilách (7,5%) a v obsahu rekta (7,4%), méně často na jazyku (5,1%), povrchu kůže (2,8%), a na kůži v okolí rekta (1,0%). Celkem 88 % kmenů náleželo sérotypu O:3, jeden kmen z povrchu kůže byl určen jako sérotyp O:5 a 8 kmenů nebylo specifikováno. Za použití referenční agarové diluční metody byla testována citlovost vůči šesti antimikrobiálním látkám (tetracyklin, kyselina nalidixová, chloramfenikol, erythromycin, ciprofloxacin, gentamicin). Kmeny vykazovaly vysoké hodnoty MIC u erythromycinu and tetracyklinu. Na druhou stranu byly citlivé ke kyselině nalidixové, gentamicinu, chloramfenikolu a ciprofloxacinu, vůči němuž byla zjištěna největší citlivost. (cs)
- Between 2005 and 2007, the incidence of Y. enterocolitica in pigs and particularly of its human pathogenic serotypes O:3 and O:9, was monitored. In 1 706 samples collected from the tongue, skin surface, skin surface near the rectum, rectal content, and tonsils, 76 pathogenic strains of Y. enterocolitica were identified. Y. enterocolitica was found most frequently on the tonsils (7.5%) and in rectal content (7.4%), and less frequently on the tongue (5.1%), skin surface (2.8%), and skin surface near the rectum (1.0%). Eighty-eight per cent of the strains belonged to the serotype O:3, one strain isolated from skin surface was identified as serotype O:5, and 8 strains were not specified. Using the reference agar dilution method, susceptibility to six antimicrobial agents (tetracycline, nalidixic acid, chloramphenicol, erythromycin, ciprofloxacin, and gentamicin) was tested. The strains showed high MIC levels to erythromycin and tetracycline. On the other hand, they were susceptible to the nalidixic acid,
