摘　　要：自2001年以来,湖北部分猪场断奶仔猪出现不明原因的红斑症状并伴随高热现象,病死率高达60%。为了探索其主要致病因素,对来源于22个发病猪场的108份病料进行实验室诊断。结果108份病料中猪圆环病毒2型(PCV-2)、猪繁殖与呼吸综合征病毒(PRRSV)、猪瘟病毒(CSFV)、猪附红细胞体(E.suis)和猪弓形虫的检出率分别为83.3%、33.3%、22.2%、48.1%和14.8%;同时存在PCV-2、PRRSV和E.suis等不同程度的混合感染现象,其中PCV-2和E.suis混合感染最为严重,阳性率达32.4%。表明湖北省部分"红斑病"发病猪场均不同程度存在PCV-2、PRRSV和附红细胞体感染的现象,特别是PCV-2感染情况极为严重,提示PCV-2等免疫抑制性疾病可能是湖北省一些猪场出现红斑症状的主要原因。From 2001 ,＂Swine red spot disease（SRSD）＂ with high fever syndrome spreaded in weaning piglets from some pig farms of Hubei province, and the mortality of SHFS was about 40%. To investigate the causative agents of SRSD. The 108 clinical samples from 22 pig farms which suffered the disease we collected and carried out the laboratory diagnosis. The results showed that the positive rates of PCV-2,PRRSV, CSFV, E. suis and porcine Toxoplasma from clinical samples were 83. 3%,33.3%,22. 2%, 48. 1% and 14.8%, respectively. At the same time, there were mixed infection within the PCV-2, PRRSV and E. suis. The mixed infection within the PCV-2 and E. suis was so serious that the positive rate was 32.4%. The results indicated that the SRSD in this survey were mainly infected by the PCV-2, PRRSV and E. suis in different digree, especially the PCV-2. The PCV-2 and other immunodepression diseases were possiblly the main etiological factors of SRSD in some pig farms in Hubei province.
