Genetic transfer of Salmonella typhimurium and Escherichia coli lipopolysaccharide antigens to Escherichia coli K-12.
Escherichia coli K-12 varkappa971 was crossed with a smooth Salmonella typhimurium donor, HfrK6, which transfers early the ilv-linked rfa region determining lipopolysaccharide (LPS) core structure. Two ilv(+) hybrids differing in their response to the LPS-specific phages FO and C21 were then crossed with S. typhimurium HfrK9, which transfers early the rfb gene cluster determining O repeat unit ...
متن کاملScreening for cross-reacting capsular polysaccharide K antigens of Escherichia coli using antiserum agar.
Agar plates containing antiserum against group B meningococcus or Haemophilus influenzae type b were used to determine the prevalence of cross-reacting K1 and K100 capsular polysaccharide antigens in 265 isolates of disease-causing Escherichia coli. K1 antigen was found in 22% of isolates from various sites. K100 antigen was found in only three isolates. This technique is a convenient method to...

In this study, it has been our purpose to isolate and serotype enteropathogenic E. coli, salmonella and shigella and determine their resistance to antibiotics. 502 swab specimens were collected during mid-July to midNovember. 1986. from two children's hospitals in Tenran. From 502 cultured specimens. 108 specimens were positive for salmonella. shigella and enteropathogenic E. coli. corresp...
