Abstract

Summary

The frequency of electrophoretic types B (fast mobilities) and B (slow mobilities) of carboxylesterase B, and α-haemolysin and mannose-resistant haemagglutinin (MRHA) production were compared in 705 strains of isolated from cases of septicaemia, urinary tract infection (UTI) and other extra-intestinal infections from different geographical origins, in particular France, America (USA and Canada) and Oceania (Australia and New Zealand). In all groups of strains, whether classified according to their clinical or their geographical origin, electrophoretic type B was phenotypically linked with α-haemolysin and MRHA production. Haemolytic type B strains were isolated more frequently from France and Oceania than America whereas the proportions demonstrating production of MRHA were similar among the three groups. Type B strains were more frequently isolated from UTI and other infections than from septicaemia. This is attributed to the high frequency of immunocompromised subjects in the septicaemia group. Our results establish the suitability of using the type B of carboxylesterase B as a molecular marker for highly pathogenic strains implicated in extra-intestinal infections in man.
