摘要
Abstract
In order to identify the prevalence of bruellosis in Chenzhou City,Hunan Province,production data of cattle and sheep in the city were firstly collected from May to June 2023 using a cross-sectional method,farms and individuals were selected using a two-stage sampling method,and blood samples were collected for detection of antibodies against Brucella.The results showed that the positive rate of brucellosis was 1.82%(95%CI:0-4.32%)at the level of cattle farm/herd,and 2.81%(95%CI:2.08%-3.55%)at the level of individual,while 3.36%(95%CI:1.56%-5.15%)at the level of sheep farm/herd,and 1.47%(95%CI:1.24%-1.69%)at the level of individual.The inventory was＜100 on both 2 positive cattle farms and 10 positive sheep farms,and≥100 on 3 positive sheep farms;positive farms/premises were mostly located in the southwestern region including Linwu County,Beihu District,Suxian District and Guiyang County;the positive rates at individual level were 0,2.81%and 1.60%on sheep breeding farms,commercial cattle farms and commercial sheep farms,respectively,and the rate of commercial cattle farms was obviously higher than that of commercial sheep farms(χ2=13.05,P＜0.001).In conclusion,brucellosis was prevalent in cattle and sheep in Chenzhou City,tending to spread sporadically at a low level,especially mainly in the southwestern of the city;there was a higher risk of brucellosis occurrence in small farms/households,and the risk of spread would be increased by the behavior of short-term fattening.For the purpose of reducing such risk,it was recommended that farms/households should strictly standardize all introduction and movement of their animals,and relevant authorities should strengthened their quarantine and supervision for all introduction and movement of all live animals.关键词
