Abstract
Canine distemper virus (CDV) triggers a severe, often fatal disease in dogs and wildlife known as canine distemper (CD). Prior research has noted significant genetic diversity and recombination among CDV isolates from different geographical regions, potentially contributing to vaccine failures. Despite this, no genetic characterization of Mongolian CDVs has been conducted. This study, isolated CDVs from three unvaccinated dogs: two 10-month-old mixed-breeds and an 18-month-old Samoyed. All exhibited CD symptoms and subsequently died. Virus isolation was conducted using Vero/dog SLAM cells, with genome sequencing performed via nanopore technology. The mixed-breed dogs were infected with non-recombinant CDV isolates, forming a sister clade to the Asia-1 lineage prevalent in Asia. The Samoyed was infected with a non-recombinant CDV isolate, classifying as Asia-4 lineage sporadically reported in some Asian countries. This sequencing data offers foundational information on genetic diversity, aiding CD control measure development and benefiting future Eurasia and Asian studies.
