Obecność i typ fimbrii występujących u czterech gatunków rodzaju Acinetobacter: A. baumannii, A. junii, A. lwoffii i A. haemolyticus określono testem hemaglutynacji z 3% zawiesiną świeżych i taninowanych erytrocytów świnki morskiej, bydlęcych oraz ludzkich grupy O i AB bez, lub z dodatkiem inhibitorów cukrowych. U szczepów każdego z gatunków dominowały he- maglutyniny MR odpowiadające fimbriom typu 3 obok których, zwłaszcza u szczepów izolowanych z układu moczowego i oddechowego, występowały dodatkowe adhezyny o różnej swoistości cukrowej.

One of the important factors contributing to the pathogenicity of bacteria is the presence of adhesines on cell surface, which facilitate colonisation in the macroorganism. The presence and type of adhesines occurring in four species of the genus Acinetobacter: A. baumannii (184), A. junii (59), A. lwoffii (65) and A. haemolyticus (22) was determined by haemagglutination test with a 3% suspension of fresh, tannic acid-treated of guinea pig, cow and human group O and AB erythrocytes, with or without the addition of one of sugar inhibitors (D- mannose, α-methylmannopyranoside, D-galactose-N-acetyl-D-glucosamine, L-fucose and D-ribose). In strains from all species, adhesines of the mannose-resistant (MR) type dominated. The mannose-sensitive (MS) type was present solely on the surface of one A. Iwoffi strains. A. baumannii (36), A. junii (8), A. Iwoffii (11) and A. haemolyticus (4) exhibited mannose-resistant hemagglutination in relation to fresh erythrocytes and that reaction was restrained by D-galactose, D-galactose and L-fucose (no other inhibitor used restrained it). The results achieved prove that cell adhesines other than those of MR type must be present on the cell surface. Additional adhesines occurred mainly in strains isolated from the respiratory and urinary tract infection simples, but were not found in isolates from blood cultures.
