In a group of 112 cats, examined during an outbreak of diarrhea, 104 (92.8%) yielded Escherichia coli with identifiable O groups as compared to 12 (21.8%) of 55 control cats apparently free of intestinal ailments. E. coli group O6 occurred in 49.1% of the cats with diarrhea, and persisted in this group of cats at about the same rate when examined for a period of ten months. E. coli group O6 was not isolated from the control group. Specimens were also collected from dogs with various clinical signs. E. coli O4 and O6 strains appear to be important potential pathogens for canine species and were found to spread from one dog to another when in close contact. E. coli group O4 was identified in ten and O6 in three of 14 dogs examined. All isolates in which the O group could be identified were hemolytic.
在一次腹泻暴发期间对112只猫进行检查，其中104只（92.8%）检出了具有可识别O群的大肠杆菌，相比之下，55只显然没有肠道疾病的对照猫中只有12只（21.8%）检出该菌。O6群大肠杆菌出现在49.1%的腹泻猫中，并且在对这群猫进行为期十个月的检查期间，该菌在这群猫中的持续检出率大致相同。对照组未分离出O6群大肠杆菌。还从有各种临床症状的犬只采集了样本。O4和O6群大肠杆菌菌株似乎是犬类重要的潜在病原体，并且发现当犬只密切接触时会在犬只之间传播。在接受检查的14只犬中，10只检出了O4群大肠杆菌，3只检出了O6群大肠杆菌。所有能鉴定出O群的分离株都具有溶血活性。
