摘　　要：为给猪病防控措施的制定提供参考,2014—2015年对山东省主要猪群疫病进行了抗原抗体检测,分析其感染状况与流行趋势。结果显示:2014—2015年间,猪繁殖与呼吸综合征(PRRS)抗原阳性率由48.10%降低到40.56%,而其抗体阳性率由74.88%提高到84.39%。伪狂犬病(PR)抗原阳性率由4.07%提高到10.86%,期间的野毒(g E)抗体阳性率和免疫(g B)抗体阳性率基本一致。猪瘟(CFS)抗原阳性率由25.80%降低到12.61%,而其抗体阳性率由56.46%提高到71.54%。除CFS在2014年第二季度高发外,PRRS和PR的发生无明显季节性,三者的抗原阳性率与抗体阳性率大致呈负相关。猪流行性腹泻(PED)抗原阳性率由65.48%提高到77.73%,其在2014年第三季度高发,而在2015年全年高发。传染性胃肠炎(TGE)仅为零星发生。猪链球菌(SS)的抗原阳性率变化不大,平均为9%左右。副猪嗜血杆菌(HPS)抗原阳性率由30.42%降低到20.22%。总之,山东省PRRS和CFS等疫病的抗原感染率呈下降趋势,抗体阳性率呈上升趋势,说明山东省的主要猪病得到一定程度地控制。同时,依据生猪养殖业中存在的问题,提出了相应的防控对策。In order to provide references for formulating the prevention and control measures,the antigens and antibodies of the main epidemic diseases of swine were detected in Shandong province from 2014 to 2015 and their infection status and epidemic trend were analyzed.The results showed that the antigen positive rate of porcine reproductive and respiratory syndrome（PRRS） decreased from 48.10% to 40.56%,while the antibody positive rate of PRRS increased from 74.88% to 84.39%.The antigen positive rate of pseudorabies（PR） increased from 4.07% to 10.86%,while the antibody positive rate of PR g E and g B in 2015 were basically same as that in 2014.The antigen positive rate of classical swine fever（CFS） decreased from 25.80% to 12.61%,while its antibody positive rate increased from 56.46% to 71.54%.The occurrences of PRRS and PR were not significantly seasonal and the incidence of CFS was high in the second quarter of 2014.The antibody positive rates of PRRS,PR and CFS were negatively correlated with their antigen positive rates.The antigen positive rate of porcine epidemic diarrhea（PED） increased from 65.48% to 77.73%.The quarterly results showed that there was high incidence in the third quarter of 2014 and throughout the whole year of 2015.Transmissible gastroenteritis（TGE） was only sporadic.The antigen positive rates of streptococcus suis（SS） in 2014 and 2015 were about 9% invariably,while the antigen positive rate of haemophilus parasuis（HPS） decreased from 30.42% to 20.22%.In short,the main epidemic porcine diseases,such as PRRS and CFS,presented a downtrend of antigen infection rates and an uptrend of antibody positive rates from 2014 to 2015 in Shandong province.It indicated that main epidemic porcine diseases were controlled in Shandong province.
