鸽副伤寒的诊断与防治内容摘要:
2、血,肝脏、肾脏均有灰白色坏死点;小肠壁水肿,粘膜出血,十二指肠尤为明显,少数病例肠壁还有黄白色粟粒大小的坏死结节;部分病例关节突出呈圆球状,切开有大量液体。 三、兰氏染色,镜检发现大小中等,两端钝圆、无芽孢、红色阴性杆菌。 取肝、脾脏、心血、肾、关节液接种于麦康凯琼脂和血液琼脂平板上,经 37培养 24 小时,在麦康凯琼脂平板上生长出大量圆形、稍隆起、无色、半透明的菌落;在血液琼脂平板上长出边缘整齐、湿润、凸起、有光泽、灰白色、直径约为 米的菌落。 挑取部分细菌接种于三糖铁琼脂斜面及底部穿刺,经 37恒温培养 24 小时后,可见在斜面上生长的菌落为白色,穿刺线上的菌落为黄色,穿刺线底部呈烟雾状黑色,琼脂斜面仍为红色。 菌能使葡萄糖、麦芽糖及甘露醇产酸产气,VP 试验阴性,吲哚试验阴性,枸橼酸盐利用试验阳性。 温于燥 5 分钟后放置、按压药敏纸片,置 37恒温箱培养 24 小时,测量其抑菌圈直径。 其结果为此菌对环丙沙星、畜禽百病清、思诺沙星敏感;红霉素、青霉素、链霉素、氟哌酸、四环素、庆大霉素、土霉素、金霉素对此菌无抑制作用。 用高敏药物畜禽百病清 100 克,加水 1000 千克,给鸽自由饮用,连续 5 天。 另外,对个别病例用恩诺沙星和环丙沙星分别注射治疗,5 天后病情得到控制。 全面消毒,因为老鼠是该病的带菌者和传染源,所以,进行了大规模的灭鼠工作。 专利查询。鸽副伤寒的诊断与防治
