摘要
应用病原分离、直接涂片镜检和间接血凝试验法对广东省26个瘦肉型种猪场的4086头种猪分别进行猪传染性萎缩性鼻炎(AR)、痢疾(SD)和支原体肺炎(MPS)的调查,结果AR、SD、MPS的阳性率分别为:1.05％、1.64％和70.04％,AR、SD各有18个场检出带菌猪,MRS检25个场全部为阳性场。这表明,广东省种猪场普遍感染AR、SD和MPS,而MPS感染最为严重,但上述三种疫病在种猪群中极少表现明显临床症状,呈一种隐性带菌状态。检验结果还说明,AR、SD和MPS感染率的高低与猪场的兽医卫生管理水平、猪群密度及通风条件有关。
Using pathogen isolation, microscopy of direct smear and indirect hemagglutination test, 4086 breeder pigs belonging to 26 breeding pig units were examined for infectious atrophic rhinitis, dysentery and myc-oplasmal pneumonia in pigs in Guangdong province. The results showed the infection rates positive for infectious atrophic rhinitis, dysentery and mycopiasmal pneumonia were 1.05 percent ( 43/4086) , 1.64 percent ( 67/4086 ) and 70.04 percent ( 2368/3381 ) .
