One male of a group of seven Pacific white-sided dolphins (Lagenorhynchus obliquidens) died after a brief period of nonspecific clinical signs. Four beluga whales (Delphinapterus leucas) and four harbor seals (Phoca vitulina) were managed in the same water system. Gross examination of the dolphin revealed only moderately enlarged mesenteric lymph nodes. Histopathology revealed small to massive numbers of gram-positive bacilli, usually intravascular, in all tissues. Bacteria were both extracellular and present in macrophages, monocytes, and neutrophils. Aerobic bacterial culture of lung, liver, kidney, and spleen yielded pure cultures of Erysipelothrix rhusiopathiae. Based on clinical course, histopathology, and bacteriology, a diagnosis of acute erysipelas septicemia was made. None of the other cetaceans or pinnipeds exhibited clinical signs.
在一组七只太平洋白侧海豚(Lagenorhynchus obliquidens)中,有一只雄性海豚在出现一段短暂的非特异性临床症状后死亡。四只白鲸(Delphinapterus leucas)和四只港海豹(Phoca vitulina)在同一水系统中饲养。对该海豚进行大体检查时,仅发现肠系膜淋巴结有中度肿大。组织病理学检查显示,在所有组织中均可见少量至大量革兰氏阳性杆菌,通常存在于血管内。细菌既存在于细胞外,也存在于巨噬细胞、单核细胞和中性粒细胞内。对肺、肝、肾和脾脏进行需氧细菌培养,结果均培养出猪红斑丹毒丝菌的纯培养物。根据临床病程、组织病理学和细菌学检查结果,诊断为急性丹毒败血症。其他鲸类动物或鳍足类动物均未表现出临床症状。
