Abstract

Canine distemper virus (CDV) is endemic in Zambia, while peste-des-petits-ruminants virus (PPRV) has not been detected. This study screened 962 farmed goats and 237 small ruminants at informal markets for PPRV antibodies using c-ELISA. A subset (n = 29) was re-analysed with virus neutralisation assays (VNA) for antibodies to PPRV and CDV due to cross-reactivity concerns. c-ELISA indicated 6.44% PPRV seroprevalence on farms and 3.80% at markets. While VNA detected no PPRV antibodies, 45% (13/29) tested positive for CDV, possibly suggesting cross-reactivity. Given the study's limitations, further research is needed to determine whether PPRV is present in Zambia and assess potential cross-reactivity.

在赞比亚小反刍动物害虫-小反刍动物病毒（PPRV）监测期间检测到犬瘟热病毒（CDV）中和抗体。

犬瘟热病毒（CDV）在赞比亚流行，而小反刍动物害虫病毒（PPRV）尚未发现。本研究采用c-ELISA法对962只养殖山羊和237只非正规市场小反刍动物进行PPRV抗体检测。由于交叉反应性的考虑，用病毒中和试验（VNA）重新分析了一个亚群（n = 29）的PPRV和CDV抗体。c-ELISA检测猪场PPRV血清阳性率为6.44%，市场阳性率为3.80%。而VNA未检测到PPRV抗体，45%（13/29）检测到CDV阳性，可能提示交叉反应。鉴于这项研究的局限性，需要进一步的研究来确定PPRV是否在赞比亚存在，并评估潜在的交叉反应性。
