Analysis of P fimbriae on Escherichia coli O2, O4, and O6 strains by immunoprecipitation.

摘要: P fimbriae on Escherichia coli O2, O4, and O6 strains were analyzed by immunoprecipitation. Fimbrial extracts prepared from a total of 35 tested for precipitation with four anti-P-fimbria sera. The overall fimbrial composition the was related to O:K:H serotype, two three variants per strain found most O4 some strains. O2 strains, in contrast, showed only one antigenic variant strain, which serologically unrelated those results stress multiplicity serological complexity E. fimbriae. Images
