The aim of the work was to determine by the use of the haemagglutination test and slide agglutination test specific and unspecific fimbria of Escherichia coli isolated from diarrhoeic and normal piglets. The obtained results were compared with the cell aggregation test (SAT) in order to evaluate its efficiency to determine fimbria of E. coli. It was found a close relationship between a hydrophobic properties of bacterial cell surface (positive SAT) and the presence of fimbrial antigens K88 and 987P (95.7% and 83.6% of agreement of the SAT with the agglutination test). Only 33.7% of strains having unspecific fimbria F₁ possesed hydrophobic properties. It was found that the SAT test may be applied for screening of the specific fimbria of E. coli.
