Pod koniec lat osiemdziesiątych opisano nową grupę enteroagregacyjnych szczepów Escherichia coli, które skupiają potencjał chorobotwórczy wszystkich, dotychczas poznanych patogenów jelitowych i które charakterystycznie związane są z przewlekłymi, trwającymi nawet kilka miesięcy, biegunkami.

Enteroaggregative strains of E. coli (EAEC) are an important agents possessing among many virulence factors, aggregative fimbria AAF hcmagglutinating in the presence of mannose human group A or/and rats erythrocytes. The aim of the study was to determine the correlation between the presence of AAF fimbria and pattern of adherence in vitro. Tested strains of E. coli were obtained from children with diarrhea (133 strains) and healthy children (105 strains). Among strains of E. coli from children with diarrhea 81 (61%) showed the presence of AAF fimbria and 19 (23%) were adhering in aggregative pattern. In the group of strains of E. coli isolated from healthy children 31 (30%) were AAF positive and 8 (25,8%) of them presented aggregative adherence. Examination of AAF fimbria only dose not allow to distinguish EAEC strains. The data showed the participation of EAEC strains in diarrhea of children below 3 years old.
