Rattlesnake envenomation is an important cause of morbidity and mortality in humans and animals in the southwestern United States and elsewhere. Two Visayan warty pigs (Sus cebifrons) from a regional zoo were submitted for autopsy after being found dead close to a southern Pacific rattlesnake (Crotalus helleri) in their enclosure. Both pigs had severe regionally extensive cutaneous, subcutaneous, and muscle hemorrhage and edema with myonecrosis. Additionally, both pigs had lesions consistent with puncture wounds within the oral cavity, and one pig had a similar wound on a forelimb. The history, and gross and histologic findings, were consistent with envenomation by rattlesnake bite. There are few documented cases of snakebite envenomation in pigs, and it had been suggested that pigs may have some degree of resistance to envenomation. Our results indicate that warty pigs are susceptible to the action of rattlesnake venom.

响尾蛇毒液是美国西南部和其他地方人类和动物发病和死亡的一个重要原因。来自一个地区动物园的两只米沙鄢疣猪 ( Sus cebifrons ) 在被发现死在一条南太平洋响尾蛇 ( Crotalus helleri ) 附近后被提交尸检。) 在他们的外壳中。两头猪都有严重的局部广泛的皮肤、皮下和肌肉出血和水肿并伴有肌坏死。此外，两只猪的损伤与口腔内的穿刺伤一致，一只猪的前肢也有类似的伤口。病史、大体和组织学发现与响尾蛇咬伤一致。很少有关于猪被蛇咬毒液的记录案例，有人认为猪可能对毒液有一定程度的抵抗力。我们的研究结果表明，疣猪容易受到响尾蛇毒液的影响。
