A Cross-sectional Survey on Bovine and Ovine Brucellosis in a County-level City of Yantai City,Shandong Province in 2025
摘要
Abstract
In order to investigate the prevalence and epidemiological characteristics of bovine and ovine brucellosis in a county-level city of Yantai City,Shandong Province,the disease was detected using rose bengal plate agglutination test(RBPT)and serum agglutination test(SAT)under a census sampling strategy.The results showed that the population apparent and true prevalence was 1.83％and 1.02％(95％CI:0-4.22％),respectively,and the individual apparent prevalence was 0.40％,indicating a relatively low infection level and a stable controlled status.The population apparent prevalence was the highest on farms where cattle and sheep were raised together,followed by farms/households where only sheep were kept(2.06％),and the lowest on those with cattle only(0.49％).Statistically significant differences were observed in both population(x2=8.240,P=0.016)and individual apparent prevalence(x2=41.453,P＜0.001)in different farming practices.Sheep farms exhibited a higher overall prevalence than cattle farms,no significant difference was observed in herd-level apparent prevalence between the two farm types(x2=2.887,P=0.089);however,the individual-level apparent prevalence differed significantly(x2=14.197,P＜0.001).The highest population apparent prevalence(5.26％)and the lowest individual apparent prevalence(0.03％)were found on farms with more than 200 sheep,whereas the opposite pattern was observed on smallholder farms with fewer than 50 sheep,i.e.,the lowest population apparent prevalence(1.96％)and the highest individual apparent prevalence(0.89％).Positive premises were mainly distributed along urban arterial roads and expressways,and their quantity was not positively correlated with their inventory.To this end,farms/households should be guided to avoid mixed farming of different species,and to implement quarantine and isolation when introducing animals;and local authorities should improve regulation for animal movement and disinfection at disinfection centers,further control,trace and monitor any positive premises,and timely eliminate any positive animals,thereby comprehensively promote regional eradication of brucellosis.关键词
