Fecal samples obtained from wild boar habitats are useful for the surveillance of diseases in wild boar populations; however, it is difficult to determine the species of origin of feces collected in natural habitats. In this study, a fecal IgA ELISA was evaluated as a method for identifying the porcine species from fecal samples. Both domestic pigs (Sus scrofa domestica) and wild boars (Sus scrofa coreanus) showed significantly higher levels of fecal IgA than other animal species. Additionally, age dependent changes in the level of Ig A in wild boars and domestic pigs were identified; Titers of Ig A were highest in suckling period and lowest in weanling period.

猪免疫球蛋白 A 抗体与野猪（Sus scrofa）和其他动物物种粪便免疫球蛋白的交叉反应

从野猪栖息地获得的粪便样本可用于监测野猪种群的疾病；然而，很难确定在自然栖息地收集的粪便的来源物种。在这项研究中，粪便 IgA ELISA 被评估为一种从粪便样本中鉴定猪种的方法。家猪 (Sus scrofadomestica) 和野猪 (Sus scrofa coreanus) 的粪便 IgA 水平显着高于其他动物物种。此外，还确定了野猪和家猪 Ig A 水平的年龄依赖性变化；Ig A滴度在哺乳期最高，断奶期最低。
