In Argentina, enzootic pneumonia (EP) is highly prevalent and different genetic types of Mycoplasma hyopneumoniae have been identified. However, there is a lack of information about prevalence and other epidemiological aspects of EP in Mendoza province. A multiple Locus variable-number tandem repeat analysis (MLVA) targeting P97 R1, P97 R1A and P146 R3 loci was used to assess the genetic diversity of M. hyopneumoniae from clinical specimens recovered from pigs from five herds located in different districts of Mendoza province. M. hyopneumoniae could be typed from 27 bronchoalveolar lavages (BAL) specimens, and eight different MLVA types were identified. This is the first report about diversity of M. hyopneumoniae in Mendoza. Results obtained in this work allow drawing a better picture of the genetic diversity of this pathogen in Argentina.

在阿根廷，动物共生性肺炎（EP）非常流行，并且已鉴定出猪肺炎支原体的不同遗传类型。然而，关于门多萨省的流行病学和其他流行病学方面的信息缺乏。使用针对P97 R1，P97 R1A和P146 R3基因座的多基因座可变数目串联重复分析（MLVA），从门多萨省不同地区的五只猪群的猪中回收的临床标本评估猪肺炎支原体的遗传多样性。猪肺炎支原体可从27支支气管肺泡灌洗（BAL）标本中分型，并鉴定出八种不同的MLVA类型。这是有关猪肺炎支原体多样性的第一份报告在门多萨。这项工作获得的结果使人们能够更好地了解阿根廷这种病原体的遗传多样性。
