Elanco PRRS vaccine licensed by USDAJune 27, 2018Prevacent PRRS vaccine, a modified-live respiratory vaccine effective in the reduction of porcine reproductive and respiratory syndrome (PRRS), respiratory form, in piglets aged 2 weeks or older, has been licensed by the USDA, reports Elanco Animal Health, a division of Eli Lilly and Co. PRRS causes disease in two forms: a respiratory form that weakens young pigs' ability to breathe and a more severe reproductive form that causes mass deaths in pigs during late pregnancy. Since its emergence in the late 1980s, the virus has cost the swine industry millions annually in respiratory disease in piglets and reproductive failure in sows. Current estimates place the cost at $560 to $660 million annually. "PRRS has grown to be a costly and challenging disease that is difficult to control at the local, regional, and national levels," said Chris Chavis, senior director with Elanco North America Food Animal Business. "We are eager to bring producers a new product to tackle this devastating disease." The vaccine is part of Elanco's Full Value Pigs line, which includes a portfolio of products that help to control specific enteric and respiratory diseases. The viral strain in Prevacent PRRS is "highly relevant" to today's swine operations, Elanco …

KSU conducts first US livestock study with Japanese encephalitis virusJune 20, 2018North American domestic pigs could be susceptible to Japanese encephalitis virus infections, according to a study by Kansas State University (KSU) College of Veterinary Medicine researchers. The study, believed to be the first of its kind in the U.S., was published recently in Scientific Reports. "Collectively, our study demonstrates for the first time that North American domestic pigs can contribute to the Japanese encephalitis virus transmission cycle as amplifying hosts," said So Lee Park, a third-year veterinary student and concurrent doctoral student in pathobiology who was first author of the study. Japanese encephalitis virus is a mosquito-transmitted flavivirus that has human and veterinary health significance. The virus is the leading cause of vaccine-preventable encephalitis in Asia and the western Pacific, according to the Centers for Disease Control and Prevention (CDC). The virus can be maintained in a cycle between mosquitoes and vertebrates, mainly pigs and wading birds. While most human infections are mild, a small percentage of people develop encephalitis. About 1 in 4 cases of Japanese encephalitis are fatal, the CDC stated. The virus in swine can cause encephalitis in piglets and reproductive diseases in mature adult pigs. The KSU study suggests …

Auburn to strengthen vet medicine in rural KentuckyDecember 5, 2017The Auburn University College of Veterinary Medicine is directing a program to strengthen veterinary services to underserved rural populations in Kentucky through a grant provided by the U.S. Department of Agriculture's Veterinary Services Grant Program and in partnership with Kentucky veterinarians. The $237,233 grant allows the college to create a program to "develop, implement, and sustain private veterinary services through education, training, recruitment, placement and retention of veterinarians and students of veterinary medicine," said Dan Givens, DVM, Ph.D., associate dean for academic affairs at Auburn's College of Veterinary Medicine. It is one of 13 grants by USDA's National Institute of Food & Agriculture. Objectives of the grant are: Connect veterinarians serving in rural geographic areas where additional veterinarians are needed with veterinary students interested in working in those areas; Provide quality educational opportunities for veterinary students in business management and sustainability in rural veterinary practice; Provide quality continuing education at a reduced cost to veterinarians serving in designated rural areas of unmet needs; Provide business management education and practice sustainability consultation to rural veterinary practitioners in underserved areas, and Facilitate and create networking opportunities that assist graduating veterinarians with transitioning into sustainable careers in rural underserved …
KSU researcher protects pigs against PRRS during reproductionDecember 1, 2017 Raymond "Bob" Rowland, Ph.D., professor of diagnostic medicine and pathobiology in the Kansas State University College of Veterinary Medicine, has created a way to protect swine offspring from porcine reproductive and respiratory syndrome (PRRS) virus during pregnancy. Rowland has found that mothers without the CD163 protein are resistant to the PRRS virus and give birth to healthy, normal piglets. The work appears in Nature's Scientific Reports. "We have created a protective shell against the PRRS virus during the reproductive phase of production," Rowland said. "The offspring does not become infected during pregnancy and is born a healthy piglet. During this critical phase of production, we have essentially ended a disease." The PRRS virus causes disease in two forms: a respiratory form that weakens young pigs' ability to breathe and a more severe reproductive form that causes mass deaths in pigs during late pregnancy. "The reproductive form not only has a tremendous economic impact, but also a psychological impact on people who work with pigs," said Rowland, who has spent more than 20 years studying the PRRS virus. "When we look at ways to control this disease, it really begins with reproduction. We want to keep this …
Zoetis accepting research grant proposals on controlling parasitic diseaseDecember 1, 2017Zoetis is accepting grant proposals for research into innovative approaches to help protect dogs, cattle, sheep, and poultry from parasitic diseases and to extend the efficacy of therapeutics through new formulations. Through a grant awards program, Zoetis will award a minimum of $25,000 and maximum of $150,000 to support each selected grant proposal. More than one grant may be awarded.

In cattle and sheep, the company seeks proposals that explore …
WHO urges end to antibiotics use in healthy food-producing animalsNovember 10, 2017The World Health Organization (WHO) launched new guidelines regarding the use of antimicrobials in food-producing animals, urging farmers and the food industry to stop using antibiotics to promote growth and prevent disease in otherwise healthy animals. The guidelines were announced ahead of World Antibiotic Awareness Week, Nov. 13-19. The WHO recommends an overall reduction in the use of all classes of medically important antibiotics in food-producing animals, including complete restriction of these antibiotics for growth promotion and disease prevention without diagnosis. Healthy animals should receive antibiotics only to prevent disease if it has been diagnosed in other animals in the same flock, herd, or fish population, according to the WHO. The new guidelines aim to help preserve the effectiveness of antibiotics important for human medicine. They recommend that antibiotics used in animals should be among those that are the least important to human health, and not from those classified as "critically important." The European Union barred the practice in 2006, and a US ban on use of "medically important" antibiotics kicked in at the beginning of this year, according to the WHO. "A lack of effective antibiotics is as serious a security threat …
Synthetic Genomics, Ceva partner to develop livestock vaccinesNovember 1, 2017 Synthetic Genomics Inc. announced that it has partnered with Ceva Santé Animale to utilize Synthetic Genomics' next-generation synthetic RNA replicon platform to develop vaccines for livestock. Synthetic Genomics' RNA replicons are programed to deliver genetic instructions to a body's own cells to unleash a powerful immune response against a specific disease, the company said. These RNA replicons carry the genetic code for a self-replication engine as well as antigens that signal for an immune response. The self-amplifying, RNA-based vaccine triggers rapid and immediate antigen expression within host cells, which induces strong T cell and B cell responses. These fully synthetic vaccines have lower dose requirements and simplified manufacturing compared to traditional vaccine approaches, according to the announcement. "We have made tremendous progress to date in programming RNA to develop next-generation vaccines that are multigenic, tunable and, most importantly, scalable for commercially competitive markets such as animal health," said Synthetic Genomics CEO Dr. Oliver Fetzer. "This partnership with Ceva, a leader in animal health, highlights the promise in deploying our synthetic biology capabilities to build RNA systems capable of improving global health in a variety of ways." Financial terms of the agreement were not …
