Peste-des-Petits-Ruminants (PPR) or goat plague is an important viral disease of sheep and goats caused by the small ruminant morbilli virus or PPR virus (PPRV). Long non coding RNAs (lncRNA) and circular RNAs (circRNA) play a pivotal role in several biological processes including regulation of virus-host interactions. The present study explored the expression of lncRNA, circRNA and their functions in PPRV infected B-lymphocyte (B95a) cells. The results revealed a total of 4531 lncRNA and 2348 circRNA expression in both mock and PPRV infected samples. Analysis of differentially expressed (DE) RNA identified 123 DE-lncRNA and 39 DE-circRNA as significantly dysregulated. Functional analysis of cis-target genes of DE-lncRNA indicated activation of TCF dependent WNT signaling and PKN1 stimulated transcription process. Interactions (sponging) of microRNA (miRNA) revealed 344 DE-lncRNA-miRNA and 93 DE-circRNA-miRNA pairs. The competing endogenous RNA (ceRNA) network of lncRNA/circRNA-miRNA-mRNA in PPRV infected B95a cells was represented by 69 ceRNA pairs. We validated the DE-circRNA by targeted amplification and sequencing of back spliced junctions (BSJs). The present study revealed a profile of lncRNA, circRNA and their potential ceRNA network in PPRV infection. The results provide insight for better understanding of PPRV-host interactions.

The first PPR outbreak in Greece was laboratory confirmed in the region of Thessaly on the 11th of July 2024. A total of 86 farms in multiple regions were infected and no additional outbreaks have been reported in Greece since 1st of November 2024. To assess the origin of PPRV identified in Greece, the sequence obtained was aligned with a curated dataset of partial N gene sequences.

Importance: Peste des petits ruminants (PPR) is a highly contagious viral disease that mainly affects small domestic ruminants. The disease has a significant socioeconomic impact, causing substantial economic losses and adversely affecting international trade.
Objective: This study examined the prevalence of antibodies against the PPR virus (PPRV) in sheep and goats and assessed the risk factors influencing the epidemiology of the disease in the Savannah district of northern Ivory Coast.

Peste-des-petits-ruminants (PPR) is an acute, contact infectious disease caused by peste-des-petits-ruminants virus (PPRV) infection. PPRV mainly infects goats, sheep and other small ruminants, posing a serious threat to the development of the livestock industry and the safety of wildlife. In this study, a competitive ELISA (c-ELISA) method for detecting neutralizing antibodies against PPRV was developed using the extracellular domain of haemagglutinin (tH) protein and a monoclonal antibody against tH protein.

Peste des petits ruminants virus (PPRV) has been classified into four lineages based on the nucleocapsid and fusion genes, with lineage IV strains being the most widely distributed. In Africa, recent epidemiological data revealed that PPRV lineage IV is increasingly displacing other lineages in prevalence, suggesting a competitive advantage in viral transmission and adaptability. Moreover, a lineage IV strain was the only confirmed strain in Europe and Asia.

Peste des petits ruminants is a highly contagious transboundary viral disease that poses a serious threat to small ruminant populations worldwide. In 2024, seven outbreaks of PPR were recorded in sheep flocks from Timiș County, marking the second confirmed incursions of peste des petits ruminants virus (PPRV) in Romania. This study aimed to document the clinical presentation, pathological findings, and diagnostic confirmation with these field outbreaks.
