2010-2011年绵阳市犬密度及犬只狂犬病病毒带毒调查报告

Analysis on dog's density and dogs infected with rabies virus in Mianyang from 2010 to 2011

目的了解绵阳市犬只密度和狂犬病病毒带毒感染状况,为防制狂犬病提供科学依据。方法北川、平武未报告过狂犬病,随机抽取2个村进行调查;在其余7个报告狂犬病病例的县市区分别抽取1个报病村和1个未报病村进行调查。调查内容包括犬密度、免疫和拴养等情况。在9个县市区采集50份犬脑组织检测狂犬病毒抗原。结果共调查9个县市区18个村,平均犬密度为0.41只/户,免疫率为81.9%,拴养率67.55%。报病村,其免疫率和拴养率均较未报病村低,但差异无统计学意义。50份犬脑组织未发现狂犬病毒抗原阳性者。结论绵阳市犬只密度较高,免疫率和拴养率低,需加强犬只管理和免疫,有效预防和控制狂犬病的发生。

Objective To understand the dog＇s density and infection situation of rabies virus in Mianyang, and provide scientific evidence for control of rabies. Methods Method Investigate 2 villages randomly in Beichuan and Pingwu, where no case of rabies was reported; and investigat 2 villages randomly in 7 counties with rabi- es, one village had reported and one village didn1 report the cases. The investigation items included dog＇s density, immunization and raising methods. Detect the rabies virus antigen for 50 samples of brain tissue in 9 counties. Results The average dog＇s density was 0.41 per family of the 18 villages. The immune rate was 81.90% and dogs tied to raising accounted for 67.55%. The immune rate of village with rabies was lower than that with no case of rabies, but the difference had no statistical significant.
