First detection and genetic characterization of peste des petits ruminants virus from dorcas gazelles “Gazella dorcas” in the Sudan, 2016-2017

In May 2017, many free-ranging dorcas gazelles ( Gazella dorcas ) with suspected signs of peste des petits ruminants (PPR) were reported in Dinder National Park, South-Eastern Sudan. Peste des petits ruminants virus (PPRV) antigen and nucleic acid were detected in specimens from these gazelles using...

Description
Summary:In May 2017, many free-ranging dorcas gazelles ( Gazella dorcas ) with suspected signs of peste des petits ruminants (PPR) were reported in Dinder National Park, South-Eastern Sudan. Peste des petits ruminants virus (PPRV) antigen and nucleic acid were detected in specimens from these gazelles using an immunocapture ELISA and a reverse transcription polymerase chain reaction (RT-PCR) assays. PPRV was also detected in four healthy semi-captive dorcas gazelles from two areas of Khartoum State. Phylogenetic analysis showed that these PPRV strains belonged to the lineage IV genotype. The present study demonstrates that gazelles are a potential wild small ruminant host for PPRV and may influence the epidemiology of PPR in the Sudan.
