【摘要】：目的了解彭山县土源性线虫感染现状,为防治工作提供科学依据。方法全县分东南西北中5个片区进行随机抽样,采用改良加藤厚涂片法检查土源性线虫卵。结果共调查974人,检出3种土源性线虫,总感染率为12.63%;其中蛔虫、钩虫、鞭虫感染率分别为10.57%、1.33%、0.72%。地区分布低山丘陵地区感染率高于平坝地区,总感染率及蛔虫的感染率差异具有统计学意义(χ2总=21.97,χ2蛔虫=14.93,P值均小于0.05)。总感染率、蛔虫、钩虫、鞭虫感染率性别差异均无统计学意义(P值均0.05)。20岁以下和31~40岁组总感染率最高,分别为15.69%和19.50%,各年龄组总感染率及蛔虫的感染率差异有统计学意义(χ2总=12.45,χ2蛔虫=13.39,P值均小于0.05)。结论与2002年调查相比,彭山县人体土源性线虫感染率呈明显下降趋势,以蛔虫感染为主,低山丘陵地区感染较严重,防治工作任重道远。今后防治工作重点地区为低山丘陵地区。
[Abstract]:Objective to understand the status of soil-derived nematode infection in Pengshan County and provide scientific basis for prevention and control. Methods the whole county was randomly sampled from 5 regions in the east, south, north and west. The modified Kato thick smear method was used to examine the eggs of the soil-derived nematode. Results A total of 974 people were investigated. The total infection rate was 12.630.The infection rates of Ascaris lumbricoides, hookworm and Trichuris were 10.57 and 1.330.72, respectively. The infection rate of Ascaris lumbricoides in hilly areas was higher than that in Pingba area (蠂 ~ 2 = 21.97, 蠂 ~ 2 = 14.93 P < 0.05), and the total infection rate and Ascaris infection rate were significantly higher than those in Pingba area (蠂 ~ 2 = 21.97, 蠂 ~ 2 = 14.93 P < 0.05). The total infection rate of Ascaris lumbricoides hookworm and Trichuris trichuris were not significantly different (P < 0.05). The total infection rate was the highest in the group under 20 years old and the age group of 31 ~ 40 years old. The total infection rate of Ascaris lumbricoides and the infection rate of Ascaris lumbricoides in each age group were 15.69% and 19.50%, respectively. There were significant differences in the total infection rate and the infection rate of Ascaris lumbricoides (蠂 ~ 2 = 12.45, 蠂 ~ 2 = 13.39 P < 0.05). Conclusion compared with the investigation in 2002, the infection rate of earth-derived nematode in Pengshan County is obviously decreasing, the infection of Ascaris lumbricoides is the main infection, and the infection is more serious in the low mountains and hills, so the prevention and control work is a long way away. In the future, the key area of prevention and control work is the low mountain and hilly area.
