【摘要】 试验共调查不同年龄体重的猪3800头,其中体重10～30kg猪1500头,30～60kg猪1200头,60kg以上育肥猪800头,成年母猪300头,按20%比例耳静脉采血化验。选择红细胞感染率在50%以上的患病猪1171头,随机分为5个组,分别用附红细胞体注射液、长效土霉素、血虫净、血虫净配合长效土霉素和远征霉素进行治疗。同时将猪附红细胞体耳静脉感染家兔,并将感染兔的全血接种健康兔且同未接种健康兔同笼饲养,结果表明:猪附红细胞体的感染率达80%以上,发病率为47%,以小兔最高。应用血虫净配合远征霉素或长效土霉素治疗,治愈率可达80%以上,60kg以上成年猪治愈率量高。猪附红细胞体可以通过血液传染给家兔,同笼接触饲养也可传染。更多还原

【Abstract】 Twenty precent of 3800 swine’s ear blood samples was tested in this experiment, which includes 1030/piglet 1500, 3060kg fatting pig 1200, over 60kg fatting pig 800 and sow 300. 1 171 swines which were more than fifty precent of erythrocyte infected by Eperythrozoon(EH) were divided into five groups and were treated with swine EH injection, terramycin, diminazene aceturate, diminazene aceturate and tevramycin, diminazene aceturate and yuan zhengmycin, respeclively. The rabbits were inoculated with EH, the blood of infected rabbits was used for the health rabbits. The infection rate of swine’s EH is eighty precent, the morbidity is fortyseven percent and the piglet’s infective rate is the highest. The best treatment is Diminazene Aceturate combining Terramycin or yuan zhengmycin and the cure rate is over 80%. The swine EH can infect rabbit through blood and the infected rabbits can infect heath rabbit through blood. Swine EH can be infected by contacting in raising.更多还原
