A phylogenetic analysis of samples taken from reported outbreaks of peste des petits ruminants virus (PPRV) in Georgia revealed a closer relationship to viruses from northern and eastern Africa than to viruses from countries closer to Georgia. This finding has crucial implications for the control of PPRV in the region.

The present study aimed to investigate the episodes of per-acute mortality due to peste des petits ruminants (PPR) that resulted in the death of 30 animals of different species of cervids, namely, barking deer, four-horned antelope, hog deer, thamin, and mouse deer in the State Zoo of Assam, a northeastern state of India. The affected animals showed no to limited clinical signs. However, the necropsy and histopathological findings were highly suggestive of PPR virus (PPRV) infection observed in domestic small ruminants.

Peste des Petits Ruminants (PPR) is a highly contagious transboundary viral disease of small ruminants with significant economic implications caused by the Peste des Petits Ruminants virus. This study employs mathematical modeling to investigate the impact of imperfect PPR vaccines and restocked small ruminants on the transmission dynamics of PPR. A deterministic mathematical model is developed by incorporating vaccinated and restocked subpopulations into the classical SEIR model.

Peste des petits ruminants virus (PPRV), a single-stranded negative-sense RNA virus with an envelope, belongs to the Morbillivirus in the Paramyxoviridae family and is prevalent worldwide. PPRV infection causes fever, stomatitis, diarrhoea, pneumonia, abortion and other symptoms in small ruminants, with a high mortality rate that poses a significant threat to the sustainability and productivity of the small ruminant livestock sector. The PPRV virus particles have a diameter of approximately 400-500 nm and are composed of six structural proteins: nucleocapsid protein (N), phosphoprotein (P), envelope matrix protein (M), fusion protein (F), haemagglutinin protein (H) and large protein (L).

Background: Peste des petits ruminants (PPR) is an acute or subacute, highly contagious, and economically important, transboundary disease of small ruminants caused by Peste des petits ruminants virus (PPRV).
Objectives: The objective of this study was to determine the seroconversion rate in PPR vaccinated flock of sheep (Sekela district) and the seroprevalence of PPRV in unvaccinated flocks of sheep and goats (Yilmanadensa district).
Methods: A cross-sectional study was conducted from January to March 2022 in two selected districts of West Gojjam zone, Ethiopia.
