Sequential stool cultures submitted for routine culture were screened for the presence of CDC group DF-3. Of 690 specimens, 11 (1.6%) yielded moderate to heavy growth of DF-3. Information on the 11 patients from whom these specimens were obtained showed that 4 had a history of prolonged diarrheal disease that resolved after specific therapy to eradicate DF-3, while for the other 7 patients no clear role could be established. Microbiological characterization of the stool isolates and 10 CDC strains of DF-3 suggested the presence of two subtypes within the group. Antibiotic susceptibility studies showed DF-3 to be relatively resistant to a wide variety of antibiotics.
对提交进行常规培养的系列粪便培养物进行筛选,以检测是否存在疾病控制与预防中心(CDC)DF-3组细菌。在690份标本中,11份(1.6%)培养出中度至重度生长的DF-3。从这些标本获取的11例患者的信息显示,4例有长期腹泻病史,在采用特异性疗法根除DF-3后病情缓解,而另外7例患者未明确其作用。粪便分离株及10株CDC DF-3菌株的微生物学特征表明该组内存在两个亚型。药敏研究显示DF-3对多种抗生素相对耐药。
