Ulcers of the oral cavity, esophagus, and gastric compartments of South American camelids are uncommon. Multifocal-to-coalescing ulcers were identified in the oral cavity, esophagus, and/or gastric compartments of 5 alpacas submitted for postmortem examination. was isolated from the lesions in all alpacas, in combination with other aerobic and anaerobic bacteria. In 4 of these cases, -associated lesions were considered secondary to neoplasia or other chronic debilitating conditions; in 1 case, the alimentary ulcers were considered the most significant autopsy finding. It is not known if this agent acted as a primary or opportunistic agent in mucosal membranes previously damaged by a traumatic event, chemical insult, immunodeficiency, or any other debilitating condition of the host.
南美骆驼科动物口腔、食道和胃部的溃疡并不常见。在提交进行尸检的5只羊驼的口腔、食道和/或胃部发现了多灶性至融合性溃疡。在所有羊驼的病变部位均分离出了[具体病原体名称未给出]，同时还伴有其他需氧菌和厌氧菌。在其中4例病例中，与[该病原体名称]相关的病变被认为是继发于肿瘤或其他慢性衰弱性疾病；在1例病例中，消化道溃疡被认为是最重要的尸检发现。尚不清楚该病原体在先前因创伤性事件、化学损伤、免疫缺陷或宿主的任何其他衰弱状况而受损的黏膜中是作为原发性病原体还是机会性病原体起作用。
