The javelina, or collared peccary (Pecari tajacu), is indigenous to Arizona, New Mexico, and Texas in the United States and ranges throughout Latin America. From June 2004 to April 2005, an estimated 105 javelinas died in a mortality event that occurred in Tucson, Arizona, and neighboring areas. Clinical signs observed in sick animals included emaciation, dehydration, lethargy, and diarrhea. In addition, some animals showed labored breathing and hind limb weakness. We necropsied 34 animals, and enteritis was the most frequent clinical sign, followed by colitis, pulmonary congestion, and pneumonia. The only consistent findings were isolations of Clostridium perfringens type A and multiple Salmonella serotypes. Although it is likely that these javelinas ultimately succumbed to salmonellosis, it is unclear whether other unidentified underlying factors were involved. This is the first reported case of widespread salmonellosis in free-ranging javelinas.
野猪，即领西貒（Pecari tajacu），原产于美国的亚利桑那州、新墨西哥州和得克萨斯州，分布于拉丁美洲各地。2004年6月至2005年4月期间，亚利桑那州图森市及周边地区发生了一起死亡事件，估计有105头野猪死亡。患病动物出现的临床症状包括消瘦、脱水、嗜睡和腹泻。此外，一些动物表现出呼吸困难和后肢无力。我们对34只动物进行了尸检，肠炎是最常见的临床症状，其次是结肠炎、肺充血和肺炎。唯一一致的发现是分离出A型产气荚膜梭菌和多种沙门氏菌血清型。虽然这些野猪最终可能死于沙门氏菌病，但尚不清楚是否有其他未查明的潜在因素。这是首次报道的野生野猪中广泛发生沙门氏菌病的病例。
