Major outer membrane proteins were isolated from 36 Escherichia coli strains representing six common clones of the O2 and O78 serogroups implicated in avian colisepticemia. Clonal relationships among isolates were inferred from an analysis of polymorphism at 20 enzyme-encoding loci detected by multilocus enzyme electrophoresis. For isolates of these clones, there was a high concordance (>90%) between identity in multilocus genotype and major outer membrane protein patterns. The results indicate that major outer membrane protein patterns discriminate among the genetically different clonal groups that constitute the heterogeneous O2 and O78 serogroups associated with avian disease.
