Abstract

Thirty-two trapper-caught nutria (Myocastor coypus) from East Baton Rouge, Iberville, Tangipahoa, and St. Helena Parishes in Louisiana (USA) were sampled for several disease agents. Antibodies against Toxoplasma gondii, Chlamydia psittaci, Francisella tularensis, Leptospira spp., and encephalomyocarditis virus were detected in 7%, 14%, 0%, 7%, and 0% of nutria, respectively. Both animals seropositive for leptospirae were positive for L. interrogans serovar canicola. No Salmonella spp. were isolated from feces, and no Giardia spp. were seen in trichrome-stained fecal preparations.

摘要

对从美国路易斯安那州东巴吞鲁日、伊贝维尔、坦吉帕霍阿和圣赫勒拿教区捕获的32只南美水獭（Myocastor coypus）进行了多种病原体采样。在南美水獭中，分别检测到7%、14%、0%、7%和0%的水獭对刚地弓形虫、鹦鹉热衣原体、土拉弗朗西斯菌、钩端螺旋体属和脑心肌炎病毒产生抗体。两只钩端螺旋体血清阳性的动物对犬型问号钩端螺旋体血清型呈阳性。粪便中未分离到沙门氏菌属，在三色染色的粪便标本中未发现贾第虫属。
