Sažetak

U ovom radu su prikazani rezultati patomorfoloških nalaza i utvrđivanja prisustva različitih gena za antigene E. coli kod zalučene prasadi na gazdinstvima u Mađarskoj, Rumuniji i Srbiji. Dokazivanje antigena je vršeno lančanom reakcijom polimeraze (PCR). Većina izolata je posedovala gene za enterotoksin i adhezine fimbrija. Ukupno je ispitano 351 uzoraka koji su poticali od prasadi sa dijarejom (69), edemskom bolešću (35), mršavljenjem posle odbijanja - zalučivanja (240) i hemoragičnim gastroenteritom (2). Dominantni genotipovi su bili F4 LT STb i F18 STa STb SLT i ovaj nalaz se može tumačiti regionalnom klonskom ekspanzijom.
