猪密螺旋体痢疾诊治

Diagnosis and Treatment of Swine Treponema Pallidum Dysentery

猪密螺旋体痢疾是由密螺旋体感染肠道所引发的一种消化道传染性疾病,临床上该种致病原会引起猪大肠粘膜出现卡他性炎症出血和坏死性出血。养殖场的猪感染该种疾病后,会表现为持续性腹泻,身体逐渐消瘦,存在明显脱水现象,同时在腹泻物中还会存在大量黏液和出血性内容物,极易造成猪群死亡。部分年龄较小的猪即便能恢复健康,也会表现为生长发育迟缓,甚至会停止生长发育,使养殖场淘汰率显著升高,给养殖场带来巨大经济损失。该文主要论述猪密螺旋体痢疾的临床症状、病理变化、诊断方法和防治措施。
