New DIVA vaccine candidates against peste des petits ruminants virus

Two new vaccine candidates that could differentiate between vaccinated and infected animals and contribute to the goal of global eradication of peste des petits ruminants virus (PPRV) have been developed by researchers at The Pirbright Institute. In a study published in Viruses, researchers explored ways to create live attenuated DIVA (Differentiating Infected from Vaccinated Animals) […]

Study finds Cryptosporidium spp. widespread across dairy farms in Western Europe

Collaborative research led by the University of Kent has found the prevalence of Cryptosporidium spp. across dairy cattle farms in Western Europe to be greater than previously thought. The study, published in Microorganisms, suggests cattle as a possible carrier of zoonotic Cryptosporidium parvum subtypes, which could pose a threat to human health. Samples were collected […]

Indicators for suspicion of avian influenza on duck farms

Wageningen Bioveterinary Research (WBVR) investigated if and to what degree mortality and production data could signal possible outbreaks of highly pathogenic avian influenza (HPAI) on duck farms. The results, published in Pathogens, could be used to provide guidelines to farmers and veterinarians to report suspected outbreaks. Data was collected on the daily mortality, egg production, […]

OIE calls for increased surveillance of avian influenza

The World Organisation for Animal Health (OIE) is urging countries to maintain their surveillance efforts and to continue timely reporting of avian influenza, as outbreaks in poultry and wild birds intensify. Since the beginning of May 2021, outbreaks of high pathogenicity avian influenza (HPAI) have been confirmed in more than 40 countries from different regions […]

Deer may be a reservoir host for SARS-CoV-2

Following a USDA study showing that 40% of white-tailed deer in the USA had antibodies against Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), researchers tested the hypothesis that infection and subsequent transmission of SARS-CoV-2 of deer occurs in nature. In a study posted on the pre-print server bioRxiv, yet to be peer-reviewed, a total of […]

Bovine TB: genetic contact tracing could help control outbreaks

The use of genetic contact tracing to identify the source of a bovine tuberculosis (TB) outbreak could signal a new approach in managing the disease, according to a study published in the Journal of Applied Ecology. In response to a rise in TB rates among wildlife in the eastern part of the county of Cumbria […]

Bovine respiratory disease: study of bacterial outer membrane proteins

Scientists at the United States Department of Agriculture (USDA) Agricultural Research Service (ARS) are studying outer membrane proteins (OMPs) of bacteria commonly associated with bovine respiratory disease (BRD) to identify unique proteins that can be used for future interventions against the disease. In a study published in Genome, U.S. Meat Animal Research Center microbiologist Emily […]

Research aims to improve enzootic abortion vaccines

A vaccine being developed against ovine enzootic abortion by scientists at the Moredun Research Institute has shown promising results in laboratory trials, being able to protect against abortion caused by Chlamydia abortus without the risk of causing infection in the animal. The results of the study are published in Vaccines. Ovine enzootic abortion is a […]

Cattle herds tracked to determine risk of disease spread in East Africa

Scientists teamed with farmers from rural areas of Tanzania to track herds of cattle using satellite Global Positioning System (GPS) devices, to better understand how diseases can pass from one herd to another. The results of the study – led by the University of Glasgow and published in Scientific Reports – suggest that targeted interventions […]

Study identifies risk factors for spread of FMDV in Asia

An international project led by scientists in the World Reference Laboratory for Foot-and-Mouth Disease (WRLFMD) at The Pirbright Institute has tracked the evolution of foot-and-mouth disease virus (FMDV) over nearly 20 years to reveal how different factors affect its spread across countries of Western and Southern Asia. In their study, published in Molecular Biology and […]
