The Serological Survey and Influencing Factors Analysis of Sheep Bluetongue in Guizhou Province in 2012
摘要
Abstract
In order to understand sero-epidemiological situation of sheep bluetongue in various regions of Guizhou province for better early warning and reasonable disease prevention, 1869 sheep serum samples were collected from different regions of Guizhou province in 2012,for detection of sheep bluetongue antibody with ELISA method,and BTV antibody positive rates were analyzed with regard to the different regions, ages, gender, altitude and farming patterns. Results showed that positive serum antibody was detected in all the 7 cities in Guizhou province with a total positive rate of 25.79%(482/1869), and there were some differences in different areas with the highest positive rate in Qiandongnan region and the lowest in Tongren region, but the difference was not obvious. As with different sheep farming patterns, the general positive rate trend was in the order of free-ranging households>sheep raising village>intensive sheep farming. The impact of different age and gender on serum antibody positive rate was not big. Serum antibody positive rates at different altitudes appeared certain regularity:the positive rate at the lowest altitude was low, and was relatively high at the altitude of over 700m. However, with the rising of altitude, the serum antibody positive rate was declining. This study showed that latent BTV infection existed in various regions in Guizhou province,and reasonable and comprehensive prevention and control measures should be taken according to the different influencing factors.关键词
