【摘要】：為了解貴州省H7亞型禽流感感染情況,采用HI試驗(yàn)對(duì)全省9個(gè)地區(qū)家禽血清樣本進(jìn)行血清抗體檢測(cè),PT-PCR方法對(duì)家禽咽-肛拭子、養(yǎng)禽場(chǎng)環(huán)境樣本和野鳥糞便進(jìn)行病原核酸檢測(cè)。結(jié)果顯示:在1570份家禽血清樣本中,H7亞型禽流感血清抗體陽性率為0.45%(7/1570);在350份家禽咽-肛拭子和310份養(yǎng)殖場(chǎng)環(huán)境樣本中,均未檢測(cè)出H7亞型禽流感病毒核酸;在160份野鳥糞便中,有1份為H7亞型禽流感病毒核酸陽性,陽性率為0.63%(1/160)。試驗(yàn)提示,在貴州省養(yǎng)禽場(chǎng)中不存在H7亞型禽流感感染,但遷徙野禽中可能存在H7亞型禽流感隱性感染,應(yīng)當(dāng)引起重視。
[Abstract]:In order to understand the infection of H7 avian influenza in Guizhou Province, HI test was used to detect serum antibody in poultry serum samples from 9 areas of Guizhou Province. PT-PCR method was used to detect pathogenic nucleic acid in throat and anus swabs of poultry, environmental samples of poultry farms and feces of wild birds. The results showed that the positive rate of H7 avian influenza antibody was 0.45% (7 鈮，
