The serological and biochemical examinations of 1214 E. coli strains, isolated from clinical materials of diseased chickens are reported. About 1119 strains belong to 12 serological groups, 086, 0111, 026, 02a, 055, 0128, 084, 021, 078, 01119, 04a, and 0126. The results of pathogenicity tests using the isolated avian serotypes are described in table 1. A syndrome resembling naturally occurring coli septicaemia was reproduced by the intravenous inoculation of the E. coli serotypes, most commonly isolated from field cases. The results of in vitro sensitivity tests showed that all serotypes were sensitive to furazolidone and Nalidixique acid
