A total of 398 serum samples from free-range indigenous chickens originating from four villages in Southern Mozambique were tested for the presence of avian encephalomyelitis virus (AEV) and Pasteurella multocida (PM) antibodies through commercial enzyme-linked immunosorbent assay (ELISA) kits. AEV and PM antibodies were detected in all villages surveyed. The proportion of positive samples was very high: 59.5% (95% confidence interval (CI) 51.7-67.7%) for AEV and 71.5% (95% CI 67.7-77.3%) for PM. Our findings revealed that these pathogens are widespread among free-range indigenous chickens in the studied villages and may represent a threat in the transmission of AEV and PM to wild, broiler or layer chickens in the region. Further research is warranted on epidemiology of circulating strains and impact of infection on the poultry industry.
通过商业酶联免疫吸附测定（ELISA）试剂盒，对来自莫桑比克南部四个村庄的398份自由放养本地鸡的血清样本进行了禽脑脊髓炎病毒（AEV）和多杀性巴氏杆菌（PM）抗体检测。在所调查的所有村庄中均检测到了AEV和PM抗体。阳性样本比例非常高：AEV为59.5%（95%置信区间（CI）51.7 - 67.7%），PM为71.5%（95%CI 67.7 - 77.3%）。我们的研究结果表明，这些病原体在所研究村庄的自由放养本地鸡中广泛存在，可能对该地区野生鸡、肉鸡或蛋鸡传播AEV和PM构成威胁。有必要对流行毒株的流行病学以及感染对家禽业的影响进行进一步研究。
