The bacterium Ornithobacterium rhinotracheale is associated with respiratory disease in wild birds and poultry. In this study, the phylogenetic analysis of nine reference strains of O. rhinotracheale belonging to serovars A to I, and eight Mexican isolates belonging to serovar A, was performed. The analysis was extended to include sequences from another 23 strains available in the public domain. The analysis showed that the 40 sequences formed six clusters, I to VI. All eight Mexican field isolates were placed in cluster I. One of the reference strains appears to present genetic diversity not previously recognized and was placed in a new genetic cluster. In conclusion, the phylogenetic analysis of O. rhinotracheale strains, based on the 16S rRNA gene, is a suitable tool for epidemiologic studies.
鸟鼻气管鸟杆菌与野生鸟类和家禽的呼吸道疾病有关。在本研究中，对属于A至I血清型的9株鸟鼻气管鸟杆菌参考菌株以及属于A血清型的8株墨西哥分离株进行了系统发育分析。分析范围扩大到包括公共数据库中另外23株菌株的序列。分析表明，这40个序列形成了6个簇，即I至VI簇。所有8株墨西哥野外分离株都位于I簇。其中一株参考菌株似乎呈现出以前未被认识到的遗传多样性，并被置于一个新的遗传簇中。总之，基于16S rRNA基因的鸟鼻气管鸟杆菌菌株系统发育分析是流行病学研究的合适工具。
