This study analyzes the occurrence and distribution of phylogenetic groups of 391 strains of Escherichia coli isolated from poultry, cattle, and water buffalo. The frequency of the phylogroups was A = 19%, B1 = 57%, B2 = 2.3%, C = 4.6%, D = 2.8%, E = 11%, and F = 3.3%. Phylogroups A (P < 0.001) and F (P = 0.018) were associated with E. coli strains isolated from poultry, phylogroups B1 (P < 0.001) and E (P = 0.002) were associated with E. coli isolated from cattle, and phylogroups B2 (P = 0.003) and D (P = 0.017) were associated with E. coli isolated from water buffalo. This report demonstrated that some phylogroups are associated with the host analyzed and the results provide knowledge of the phylogenetic composition of E. coli from domestic animals.
本研究分析了从家禽、牛和水牛中分离出的391株大肠杆菌的系统发育群的发生情况和分布。各系统发育群的频率分别为：A群=19%，B1群=57%，B2群=2.3%，C群=4.6%，D群=2.8%，E群=11%，F群=3.3%。A群（P<0.001）和F群（P=0.018）与从家禽中分离出的大肠杆菌菌株相关，B1群（P<0.001）和E群（P=0.002）与从牛中分离出的大肠杆菌相关，B2群（P=0.003）和D群（P=0.017）与从水牛中分离出的大肠杆菌相关。本报告表明，某些系统发育群与所分析的宿主相关，研究结果为了解家畜大肠杆菌的系统发育组成提供了依据。
