宁夏猪附红细胞体病的流行病学调查及治疗试验

对宁夏区猪附红细胞体病进行了流行病学调查。调查结果显示,发病区和非发病区(黄河灌区、中部干旱区、南部山区)的3个不同气候类型区猪附红细胞体感染率的不同与吸血昆虫的种类和数量有关。发病区、黄河灌区、中部干旱区和南部山区(六盘山阴湿地区)猪的感染率分别为100%、71．67%、36．67%和51．57%。发病区与非发病区差异极显著(P＜0．01)；发病区、黄河灌区在昆虫活动季节与昆虫越冬季节的猪附红细胞体感染率差异显著(P＜0．05)；中部干旱区、南部山区昆虫活动季节与昆虫越冬季节的差异不显著(P＞0．05)。体外药敏试验和临床治疗试验证明,庆大霉素、长效土霉素、强力霉素、地霉素、贝尼儿、青蒿素、磷酸伯胺喹啉对猪附红细胞体病皆有效,尤以磷酸伯胺喹啉、青蒿素和强力霉素疗效显著。

Epidemiological investigation and therapeutic test of porcine eperythrozoonosis in Ningxia

Epidemiological investigation of porcine eperythrozoonosis was carried out in Ningxia of Chi- na.In results,the different infectious incidence of porcine eperythrozoonosis in the morbid area and the non-morbid areas including the Yellow River-irrigated,the center-dried and the southern mountain areas were concerned with kinds and mounts of bloodsucking insects.The incidences in the morbid,the Yellow River-irrigated,the center-dried and the southern mountain areas were 100%,71.67%,36.67% and 51.57%,respectively.The incidence in the morbid area was different significantly from that in the non morbid areas.Both in the non-morbid and the Yellow River-irrigated areas,the incidences in the insect ac- tire season were different significantly from those in the insect-surviving winter.Both in the center-dried and the southern mountain areas,the incidences in the insect active season were not different from those in the insect-surviving winter.The durg sensitivity in vitro and the clinic curative tests showed that gentami- cin,vibramycin,powermicin,drimicin,benil,arteannuin and phosphammide-gualin had the therapeutic effects on porcine eperythrozoonosis,especially phosphammide-gualin,arteannuin and powermicin.
