Mycoplasma ovis is an obligatory parasite of the erythrocytes from small ruminants (sheep, goat), wherein it causes chronic or acute anaemia. This agent shows worldwide distribution. However, its dispersion is still unknown in Argentina. This work describes an outbreak of mycoplasmosis occurred in January 2007 in a sheep flock from Rosario de la Frontera, Salta, Argentina. Adult sheep became ill with a mortality rate of 17.8%. All blood smears (n = 11) examined by Giemsa stain showed the presence of small basophile bodies characteristic of M. ovis infection, indicating a high prevalence of the infection in the flock. The molecular diagnosis (n = 9) confirmed the findings through the amplification of two fragments from the 16S rRNA gene. This is the third report of M. ovis in Argentina and the first one concomitant with clinical signs at flock level.
绵羊支原体是小型反刍动物（绵羊、山羊）红细胞的专性寄生虫，可导致慢性或急性贫血。该病原体在全球范围内均有分布。然而，其在阿根廷的传播情况仍不明确。本文描述了2007年1月在阿根廷萨尔塔省边境罗萨里奥的一个羊群中发生的支原体病疫情。成年绵羊发病，死亡率为17.8%。所有经吉姆萨染色检查的血涂片（n = 11）均显示存在绵羊支原体感染特有的小型嗜碱性小体，表明该羊群中感染率很高。分子诊断（n = 9）通过扩增16S rRNA基因的两个片段证实了这些发现。这是阿根廷关于绵羊支原体的第三次报告，也是首次伴有群体水平临床症状的报告。
