Pig coronavirus study to shed light on the virus
"This research is an important step to understanding coronaviruses in their natural hosts" - Dr Elma Tchilian.

Pirbright scientists created a PRCV model to evaluate causes. 

A porcine respiratory coronavirus (PRCV) model has been developed by researchers at the Pirbright Institute to evaluate how coronaviruses cause disease and immune responses.

Pigs were chosen for this investigation as they have similar physiology and immunology to humans, and are a natural host for PRCV. Like humans with COVID-19, pigs have varying symptoms and severity of PRCV.

The scientists hope that this study, published in Frontiers in Immunology, will reveal more about how coronaviruses infect humans, as well as pigs, and that this can help to inform measures to prevent the severity of the virus.

Dr Elma Tchilian, Head of the Mucosal Immunology group at Pirbright, commented on the study: “This research is an important step to understanding coronaviruses in their natural hosts. By exploring disease in pigs, and the mechanisms of infection we will gain insights into pig health which can also be applied to humans with COVID-19. 

“This will help to improve our knowledge of COVID-19 and the most effective controls that can be put into place to slow the spread of disease.”

Four PRCV strains were investigated, and each of these were shown to induce different degrees of lung pathology. 

Significantly, although all four of the strains replicated equally well in the upper respiratory tract and in the nose, as seen with SARS-CoV-2 in humans, the viruses which replicated in the lungs caused more severe disease. 

The strains which caused severe disease were also able to multiply in organ cultures, and it is thought that these findings will help researchers to understand how coronaviruses enter cells, replicate, and how some immune cells respond to virus infection.

Practices urged to audit neutering data

News Story 1
 RCVS Knowledge has called on vet practices to audit their post-operative neutering outcomes.

It follows the release of the 2024 NASAN benchmarking report, which collates data from neutering procedures performed on dogs, cats and rabbits.

The benchmarking report enables practices in the UK and Ireland to compare their post-operative outcomes to the national average. This includes the rate of patients lost to follow-up, which in 2024 increased to 23 per cent.

Anyone from the practice can submit the data using a free template. The deadline for next report is February 2026.

Visit the RCVS Knowledge website to complete an audit.

New guidance for antibiotic use in rabbits

New best practice guidance on the responsible use of antibiotics in rabbits has been published by the BSAVA in collaboration with the Rabbit Welfare Association & Fund (RWA&F).

The guidance is free and has been produced to help veterinary practitioners select the most appropriate antibiotic for rabbits. It covers active substance, dose and route of administration all of which are crucial factors when treating rabbits owing to the risk of enterotoxaemia.

For more information and to access the guide, visit the BSAVALibrary.
