Many swine farms employ UVC treatment in employees' personal belongings and small tools entering farms as part of the biosecurity protocol to decrease the risk of pathogen introduction into the operation. However, the UVC efficacy in some veterinary viruses is not fully evaluated. This study evaluated the efficacy of ultraviolet type C (UVC) radiation in inactivating seven relevant veterinary viruses: Swine Poxvirus (SwPV), Porcine Reproductive and Respiratory Syndrome Virus (PRRSV), Porcine Epidemic Diarrhea Virus (PEDV), Swine Influenza Virus (SIV), Bovine Viral Diarrhea Virus (BVDV), Porcine Parvovirus (PPV), and Senecavirus A (SVA).

Inferred dated phylogeny and time of the most recent common ancestor (tMRCA) demonstrated that some BVDV subgenotypes (1a, 1b, 1d, 1e, and 2b) and HoBi-like sequences clustered according to the region in which they were collected and that the diversification of subgenotypes appears to have occurred around the introduction of first Bos taurus and then Bos indicus, followed by expansion to form the adapted Brazilian breeds. The present results help to elucidate the temporal facts that led to diversification of ruminant pestiviruses in cattle in Brazil.

A desirable aspect of any carcass management method is the ability to contain and inactivate the target pathogen. The above-ground burial (AGB) technique was recently developed and proposed as an alternative carcass management method.

- Porcine circovirus 3 (PCV3) has been found in swine globally since 2016, appearing in both healthy and diseased animals.
- A study looked into whether PCV3 in the blood of sows was linked to stillbirths, analyzing 89 serum samples from newly farrowed sows.
- The results showed that while PCV3 was detected in many samples, there was no significant difference in infection rates or viral loads between sows with and without stillbirths, indicating no direct connection.
Article Synopsis
- A study looked at the blood of mother pigs (sows) to find out if certain viruses are linked to stillbirths (when piglets are born dead).
- Researchers collected blood samples from sows with stillbirths and those with healthy babies right after they gave birth.
- They found different kinds of viruses in both groups, but there was no clear connection between the viruses and whether the sows had stillbirths, meaning it’s likely these viruses are just a normal part of the sows' blood.
Bubaline alphaherpesvirus 1 (BuHV1) is a member of the family Herpesviridae, subfamily Alphaherpesvirinae, genus Varicellovirus. To date, no full genome sequence of BuHV has been published. Here, we report the complete genome sequence of bubaline alphaherpesvirus 1 (BuHV1) strain b6 (BuHV1-b6), isolated from a water buffalo (Bubalus bubalis) in 1972 in Australia.
