ABSTRACT: An outbreak of salmonellosis occurred in a group of 7 long-nosed fur seals Arctocephalus forsteri undergoing rehabilitation after being found injured and malnourished on beaches along the northern New South Wales and southern Queensland coasts of Australia. Three of the 7 individuals developed clinical disease and died within 3 d. Clinical signs included profuse diarrhea, vomiting, depression, and lethargy. Salmonella enterica subsp. enterica serovar Kentucky (S. Kentucky) was cultured from 2 of the 3 deceased animals. The other 4 animals showed similar signs and recovered following treatment. S. Kentucky (antigenic formula 8,20:i:z6) was isolated from the survivors and tissues recovered from post-mortem samples of deceased animals. The bacterium was susceptible to cephalothin and sulfamethoxazole/trimethoprim and resistant to amoxicillin-clavulanate, ampicillin/amoxicillin, tetracycline, and enrofloxacin. This organism has the potential to cause disease in aquatic wildlife, as well as posing a zoonotic threat to people who utilise the aquatic environment.

长鼻海狗爆发多药耐药的肯塔基州沙门氏菌感染

摘要:在澳大利亚新南威尔士州北部和昆士兰州南部海岸的海滩上被发现受伤和营养不良后,一组7头长鼻海狗Arctocephalus forsteri发生了沙门氏菌病暴发。7个人中有3个人发展为临床疾病,并在3天内死亡。临床体征包括大量腹泻,呕吐,抑郁和嗜睡。肠沙门氏菌亚种。肠炎沙门肯塔基(S.肯塔基)从3个死者动物2培养。其他4只动物表现出相似的体征并且在治疗后恢复。S.从幸存者中分离出肯塔基州(抗原式8,20:i:z6),并从死者动物的死后样本中回收组织。该细菌对头孢菌素和磺胺甲恶唑/甲氧苄氨嘧啶敏感,对阿莫西林-克拉维酸盐,氨苄青霉素/阿莫西林,四环素和恩诺沙星耐药。这种生物有可能在水生野生生物中引起疾病​​,并对利用水生环境的人造成人畜共患的威胁。
