Abstract:
Canine distemper outbreak and coinfections in three giant anteaters and in a maned wolf has been described. Three giant anteaters developed respiratory and digestive clinical signs after the introduction of a maned wolf to a Wildlife Rehabilitation Center. The maned wolf and two anteaters died, and one anteater was euthanized. Post mortem and histopathologic exams revealed lesions associated with numerous intraepithelial inclusion bodies, mainly in the respiratory and digestive systems. Infection by distemper virus was confirmed in all animals by RT-PCR and gene sequencing, which revealed the Europe 1/ South America 1 strain, closely related to the strain from Canis familiaris. In addition to distemper, the animals had other comorbidities, such as toxoplasmosis and salmonellosis in the maned wolf and cutaneous candidiasis in an anteater. Considering the chronology of clinical manifestation in both species and the viral characterization, it is possible that the maned wolf was the source of infection to the anteaters. This study demonstrates the importance of implementing biosecurity measures in enclosures that house animals of different species, highlighting the importance of quarantine before introduction of new animals into the same environment.
摘要:
已经描述了三个巨型食蚁兽和鬃毛狼的犬瘟热爆发和共感染。在将鬃毛狼引入野生动物康复中心后,三名巨型食蚁兽出现了呼吸和消化临床症状。狼和两个食蚁兽死了,一个食蚁兽被安乐死.尸检和组织病理学检查显示与许多上皮内包涵体相关的病变,主要是呼吸系统和消化系统。通过RT-PCR和基因测序证实了所有动物的犬瘟热病毒感染。揭示了欧洲1/南美1株,与犬科犬的菌株密切相关。除了犬瘟热,这些动物有其他合并症,如弓形虫病和沙门氏菌病,以及食蚁兽的皮肤念珠菌病。考虑到物种和病毒特征的临床表现的时间顺序,有可能是有鬃毛的狼是食蚁兽的传染源。这项研究证明了在饲养不同物种动物的围栏中实施生物安全措施的重要性,强调在将新动物引入同一环境之前隔离的重要性。
