The sensitivity to normal human serum of 144 smooth strains of Escherichia coli isolated from cases of urinary tract infection was determined. It was found that serum-sensitive and serum-resistant strains were not randomly distributed throughout the 10 O serogroups commonly associated with urinary infection. A similar distribution was observed when a group of strains isolated from rectal swabs was studied. The results indicate that serum resistance may be related to qualitative characteristics of the O antigen.
测定了从尿路感染病例中分离出的144株光滑型大肠杆菌对正常人血清的敏感性。结果发现,血清敏感型和血清耐药型菌株并非随机分布于通常与尿路感染相关的10个O血清群中。在研究从直肠拭子中分离出的一组菌株时,也观察到了类似的分布情况。结果表明,血清耐药性可能与O抗原的定性特征有关。
