The Salmonella serotypes S. Cerro and S. Newport were isolated from New Zealand sea lions (Phocarctos hookeri) and feral pigs on the Auckland Islands in the New Zealand subantarctic region. The isolates were typed by pulsed-field gel electrophoresis using Xba1 as the restriction enzyme. The isolates were indistinguishable, which suggests that Salmonella infection cycles between sea lions and pigs in this environment. Apart from a previous isolation from a single New Zealand fur seal (Arctocephalus forsteri), S. Newport has not been recorded in any animals from New Zealand, but it is associated with gastroenteritis in humans. Contamination of the marine environment by human waste is a possible source of infection for marine mammals and warrants further investigation.
从新西兰亚南极地区奥克兰群岛的新西兰海狮（胡氏海狗）和野猪中分离出了肠炎沙门氏菌血清型塞罗沙门氏菌和纽波特沙门氏菌。使用Xba1作为限制酶，通过脉冲场凝胶电泳对分离株进行分型。这些分离株无法区分，这表明在这种环境下沙门氏菌在海狮和猪之间循环感染。除了之前从一只新西兰毛皮海狮（福氏海狗）中分离出该病菌外，纽波特沙门氏菌在新西兰的任何动物中都未被记录过，但它与人类肠胃炎有关。人类排泄物对海洋环境的污染可能是海洋哺乳动物的感染源，值得进一步调查。
