【摘要】：目的了解安徽省人群隱孢子蟲感染狀況,探討感染的危險因素,為隱孢子蟲病防治提供科學(xué)依據(jù)。方法選擇安徽省潛山縣和靈璧縣為調(diào)查點,于2014年9月-2015年1月,采用改良抗酸染色法和酶聯(lián)免疫吸附試驗(ELISA)法,分別檢查調(diào)查對象糞便中隱孢子蟲卵囊和血清中隱孢子蟲特異性抗體Ig G,以確定隱孢子蟲感染情況;同時對調(diào)查對象進行問卷調(diào)查,了解隱孢子蟲感染的危險因素。結(jié)果共調(diào)查668人,其中病原學(xué)檢查635人,陽性15人,陽性率為2.36%;血清學(xué)檢查642人,陽性140人,陽性率為21.81%;有628人同時進行了病原學(xué)和血清學(xué)檢查,兩種檢查方法均為陽性者12人(潛山縣4人,靈璧縣8人),陽性率為1.94%。潛山縣與靈璧縣人群隱孢子蟲感染率分別為1.24%(4/322)和2.71%(8/295),差異無統(tǒng)計學(xué)意義(P0.05)。單因素χ2分析發(fā)現(xiàn),隱孢子蟲感染率在兒童及腹瀉人群較高;多因素Logistics回歸分析表明,隱孢子蟲感染率在飼養(yǎng)家禽人群及腹瀉人群較高。結(jié)論安徽省局部地區(qū)人群隱孢子蟲血清抗體陽性率較高,提示既往感染較為嚴(yán)重。人群隱孢子蟲感染率與低齡、腹瀉和家庭飼養(yǎng)家禽有關(guān),在今后防治工作中值得關(guān)注。
[Abstract]:Objective to investigate the infection status of Cryptosporidium in Anhui Province and to explore the risk factors for the prevention and treatment of cryptosporidiosis. Methods from September 2014 to January 2015, modified acid-fast staining method and enzyme-linked immunosorbent assay (ELISA) were used in Qianshan County and Lingbi County of Anhui Province. The specific antibody Ig-G of Cryptosporidium oocysts in feces and serum of the investigated subjects were examined to determine the infection of Cryptosporidium. At the same time, a questionnaire survey was conducted to understand the risk factors of Cryptosporidium infection. Results A total of 668 cases were investigated, including 635 cases of etiological examination, 15 cases of positive rate (2.36%), 642 cases of serological examination, 140 cases of positive rate (21.81%). Both etiological and serological tests were carried out in 628 people. 12 of them were positive (4 in Qianshan County and 8 in Lingbi County), the positive rate was 1.94%. The infection rates of Cryptosporidium in Qianshan County and Lingbi County were 1.24% (4 鈮，
