Abstract

In September 2018, an epizootic infection caused by canine distemper virus emerged in an Asiatic lion population in India. We detected the virus in samples from 68 lions and 6 leopards by reverse transcription PCR. Whole-genome sequencing analysis demonstrated the virus strain is similar to the proposed India-1/Asia-5 strain.

  • Phylogenetic analysis showed that sequences from this outbreak clustered with East-African Canine distemper virus (CDV) strains (Appendix Figure 1, http://wwwnc.cdc.gov/EID/ article/25/11/19-0120-Techapp1.pdf)

  • Phylogenetic analysis of the CDV sequences of Gir lions against available partial CDV sequences of H gene previously collected from tigers and a dog from India demonstrated a distinct cluster for sequences from India (Appendix Figure 2)
