A virulent, complement-resistant avian Escherichia co/lisolate and its avirulent, complement-sensitive, transposon-insertion mutant were compared for the purpose of revealing structures associated with complement resistance. Both had a smooth lipopolysaccharide layer, contained traT, and lacked a capsule, but the mutant possessed a 16.2-kilodalton outer-membrane protein (OMP) not present in the wild-type. This protein may be the product of a coding region interrupted by transposon insertion. Such results suggest that an OMP greater than 16.2 kilodaltons in size may be responsible for the complement resistance and virulence of this wild-type E. coli.
