Bluetongue (BT) and peste-des-petits-ruminants (PPR) are major transboundary diseases of small ruminant, which are endemic in India. Testing of bluetongue virus (BTV) and peste-des-petits-ruminants virus (PPRV) from recent outbreaks (2015-2016) in different regions of Haryana State of India revealed that 27.5% of the samples showed the presence of dual infection of BTV and PPRV. Analysis of Seg-2 of BTV (the serotype-determining protein) showed the presence of BTV-12w in several isolates. However, analysis of N gene fragment amplicons showed that viruses belong to lineage IV were most closely related to a pathogenic strain of PPRV from Delhi. This is the first report of co-circulation of PPRV lineage IV and bluetongue virus serotype 12 in the state.

Peste-des-petits-ruminants (PPR) is primarily a disease of small ruminants caused by peste-des-petits-ruminants virus (PPRV; , ), formerly the small ruminant morbillivirus. PPRV can cause significant morbidity and mortality in small ruminants and a significant economic impact. Conventional reverse-transcription PCR (RT-PCR), and probe-based and SYBR Green-based RT quantitative real-time PCR (RT-qPCR), are employed for the molecular detection of PPRV.

The aim of the present study was to investigate the frequency, genetic variability, and phylogeny of the peste des petits ruminants virus (PPRV) in ovine and caprine fetuses. During 2014 and 2017, a total of 1054 embryos/fetuses were collected in Turkey. A real-time RT-PCR assay was used for the detection of the PPRV RNA.

The enteric viruses in animals are responsible for severe and devastating losses to the livestock owners with a profound negative impact on animal, health, welfare, and productivity. These viruses are usually transmitted via the feco-oral route and primarily infect the digestive tract of the humans, bovines and different mammals as well as birds. Some of the important enteric viruses in ruminants are: Rotavirus A (RVA), Peste des petits virus (PPRV), Norovirus (NV), Bovine corona virus (BoCV) and Bluetongue virus (BTV).

Article Synopsis
- - Bluetongue virus (BTV) is a significant disease affecting sheep, and a recent case involved a flock of 300 Lacon sheep from France, examined in Qazvin, Iran, in August 2022.
- - Clinical signs observed in the sheep included symptoms like submandibular edema, fever, and stomatitis, with a high morbidity rate of 72% and a mortality rate of 7%.
- - Laboratory tests confirmed BTV in affected sheep, despite the flock being vaccinated four months prior, marking this as the first documented case of bluetongue in sheep in Iran.

Six different biosample collection cards, often collectively referred to as FTA (Flinders Technology Associates) cards, were compared for their ability to inactivate viruses and stabilize viral nucleic acid for molecular testing. The cards were tested with bluetongue virus, foot-and-mouth disease virus (FMDV), small ruminant morbillivirus (peste des petits ruminants virus), and lumpy skin disease virus (LSDV), encompassing non-enveloped and enveloped representatives of viruses with double-stranded and single-stranded RNA genomes, as well as an enveloped DNA virus. The cards were loaded with virus-containing cell culture supernatant and tested after one day, one week, and one month.
