This study aimed to determine the seroprevalence of peste des petits ruminants (PPR) and bluetongue (BT) in goats' population in the state of Meghalaya of Northeast India.
The serosurveillance study was done from the random sampling (n=598) of blood collected from five districts (Ri-Bhoi, East Khasi Hills, West Khasi Hills, Jaintia Hills and West Garo Hills) of Meghalaya. The presence of antibodies against PPR and BT in the samples was detected by indirect enzyme-linked immunosorbent assay (ELISA) method for PPR and competitive ELISA for BT.
The results showed the overall seropositivity of PPR and BT at 7.19% and 60.20%, respectively. West Garo Hills recorded the highest seroprevalence of both PPR (9.81%) and BT (68%) and 3.6% of the samples tested positive for both PPR and BT.
The random survey results indicating the presence of PPR and BT have specific implication in epidemiological perspectives since it highlights the prevalence under natural situations, where the subclinical, inapparent, or non-lethal or recovery of infection was suspected in unvaccinated animals. It also warrants further studies to suggest appropriate control measures to prevent the spread of infection.
本研究旨在确定印度东北部梅加拉亚邦山羊群体中小反刍兽疫（PPR）和蓝舌病（BT）的血清阳性率。
通过从梅加拉亚邦五个地区（里博伊、东卡西丘陵、西卡西丘陵、詹提亚丘陵和西加罗丘陵）随机抽样（n = 598）采集血液进行血清学监测研究。采用间接酶联免疫吸附测定（ELISA）法检测样本中抗PPR抗体，采用竞争ELISA法检测抗BT抗体。
结果显示，PPR和BT的总体血清阳性率分别为7.19%和60.20%。西加罗丘陵地区的PPR（9.81%）和BT（68%）血清阳性率最高，3.6%的样本PPR和BT检测均呈阳性。
随机调查结果表明PPR和BT的存在，从流行病学角度来看具有特定意义，因为它突出了自然情况下的流行情况，在未接种疫苗的动物中怀疑存在亚临床、不明显、非致死性感染或感染恢复情况。这也需要进一步研究以提出适当的控制措施来防止感染传播。
