Phibro Animal Health Corporation Announces a Significant Advance in the Development of ASF Vaccine
Phibro Animal Health Corporation (NASDAQ:PAHC) today announced it is pursuing patent protection following a significant advance in the on-going development of a vaccine for African Swine Fever (ASF). This important step in the vaccine development process involves the identification of immunogenic epitopes and proteins that show strong potential to form the basis for a vaccine against ASF.
Phibro’s R&D team and its collaborators made this identification through the use of a unique bioinformatics analysis tool in order to select...
Vaccine Investigators Use Bacterium's Own Protein Against It
A team of Agricultural Research Service (ARS) and university scientists is investigating a new “ingredient” for use in vaccinating cattle against Johne’s disease, a chronic wasting affliction that costs the U.S. dairy industry more than $200 million per year.
The ingredient in question is a type of protein on the surface of the bacterium Mycobacterium avium subspecies paratuberculosis (MAP), which causes Johne’s disease.
The researchers found that the protein, dubbed 35 kDa membrane peptide, helps the bacterium invade epithelial cells lining the cow's small intestine, thickening it and blocking the uptake of nutrients from feed or forage. This can lead to diarrhea, weight loss, diminished milk production and sometimes death. Calves are especially vulnerable and if their mothers are infected, they can acquire the bacterium from...
Vaccine Shows Promise Against Widespread Chicken Disease
A new vaccine strategy could offer protection to millions of chickens threatened by a serious respiratory disease, research shows.
Infectious bronchitis virus is highly contagious and responsible for major economic losses to the poultry industry worldwide.
Infected chickens experience weight loss, decreased egg production and impaired egg quality. They are also left vulnerable to other diseases.
Current vaccines protect against some strains of the virus, but not others. Experts say these failures are possibly linked to differences in the spike protein – the protein which enables the virus to attach to and enter cells – between strains of the virus...
