A retrospective investigation of pig tissue samples from different classical swine fever virus (CSFV) outbreaks was undertaken employing RT-PCR for possible coinfection with other swine viruses. Four samples from three different outbreaks were found to be coinfected with Japanese encephalitis virus (JEV). Phylogenetic analysis was done based on complete E gene sequenced from all four coinfected samples. This revealed a new introduction of a divergent subgroup of JEV genotype I in India. This is the first report of detection of coinfection of JEV and CSFV in pigs and the first incidence of JEV genotype I in pigs in India.
对来自不同经典猪瘟病毒（CSFV）疫情的猪组织样本进行了回顾性调查，采用逆转录聚合酶链反应（RT-PCR）检测是否可能与其他猪病毒发生共感染。发现来自三次不同疫情的四个样本同时感染了日本脑炎病毒（JEV）。基于从所有四个共感染样本中测序得到的完整E基因进行了系统发育分析。结果显示，在印度新引入了JEV基因型I的一个不同亚组。这是印度首次报告猪同时感染JEV和CSFV，也是印度首次在猪中发现JEV基因型I。
