摘要

日本猪繁殖与呼吸综合征病毒1型（PRRSV-1）和2型（PRRSV-2）合并感染的情况尚不清楚。在鹿儿岛县一个未接种PRRSV-1疫苗的农场发现了一例这种合并感染病例。RT-PCR同时检测到猪PRRSV-1和PRRSV-2基因组，分子分析证实在个别仔猪中PRRSV-1/PRRSV-2共感染。PRRSV-1株（020-P4-EU）被归类为1系（亚系：L1.2），与Unistrain®PRRS疫苗和韩国菌株高度相似。PRRSV-2株属于谱系4（聚类III）。这些发现为PRRSV-1/PRRSV-2在日本共流行提供了分子证据，提示该地区PRRSV流行病学的复杂性。

Porcine reproductive and respiratory syndrome virus type 1 and type 2 co-infection in a Japanese swine herd.

The status of co-infection with porcine reproductive and respiratory syndrome virus type 1 (PRRSV-1) and type 2 (PRRSV-2) in Japan is poorly understood. A case of such co-infection was identified on a PRRSV-1 non-vaccinated farm in Kagoshima prefecture. Both PRRSV-1 and PRRSV-2 genomes were simultaneously detected in pig samples by RT-PCR, and molecular analysis confirmed PRRSV-1/PRRSV-2 co-infection in individual piglets. The PRRSV-1 strain (020-P4-EU) was classified as lineage 1 (sublineage: L1.2), showing high similarity to the Unistrain® PRRS vaccine and a Korean strain. The PRRSV-2 strain belonged to lineage 4 (Cluster III). These findings provide molecular evidence of PRRSV-1/PRRSV-2 co-circulation in Japan, suggesting the complex epidemiology of PRRSV in this region.

期刊介绍： JVMS is a peer-reviewed journal and publishes a variety of papers on veterinary science from basic research to applied science and clinical research. JVMS is published monthly and consists of twelve issues per year. Papers are from the areas of anatomy, physiology, pharmacology, toxicology, pathology, immunology, microbiology, virology, parasitology, internal medicine, surgery, clinical pathology, theriogenology, avian disease, public health, ethology, and laboratory animal science. Although JVMS has played a role in publishing the scientific achievements of Japanese researchers and clinicians for many years, it now also accepts papers submitted from all over the world.
