Infectious bovine keratoconjunctivitis (IBK) is a common ocular disease of cattle, which is generally thought to be caused by Moraxella bovis. However, a recently characterized Moraxella, M. bovoculi, has been isolated from animals with IBK. The aim of this study was to identify and characterize strains of Moraxella spp. obtained from IBK cases in different geographic locations within Uruguay. Ribosomal gene sequencing indicated that there were two groups of isolates that showed homology with either M. bovis or M. bovoculi. Phylogenetic analysis confirmed the presence of two species as the isolates grouped in different branches of the dendrogram. Conventional biochemical characterization did not distinguish between the species; only 9/25 isolates which had genetic homology with M. bovoculi showed any differences in biochemistry.
传染性牛角膜结膜炎（IBK）是一种常见的牛眼部疾病，通常认为是由莫拉氏菌引起的。然而，最近从患有 IBK 的动物中分离出了一种被称为牛莫拉氏菌的莫拉氏菌。本研究旨在鉴定和描述从乌拉圭不同地理位置的 IBK 病例中获得的莫拉氏菌。核糖体基因测序表明，有两组分离株与莫拉氏菌或牛莫拉氏菌具有同源性。系统发育分析证实了两个种的存在，因为分离株在树状图的不同分支中聚集。传统的生化特征不能区分这两个种；只有 25 个与牛莫拉氏菌具有遗传同源性的分离株中，有 9 个在生化上存在差异。
