Duram: Mastitis, a mammary gland, is one of the most widespread and costly diseases in dairy cattle, costing an average of $ 2 billion a year worldwide. Even at this high cost, there is limited information about the genetic predisposition of bacteria that cause mastitis.
Researchers at the University of New Hampshire Veterinary Laboratory in New Hampshire, in collaboration with Cornell University colleagues, received $ 650,000 in four years for genetic analysis and research from USAID’s National Food and Agriculture Organization (NIFA) for genetic analysis and research. These bacteria cause these expensive infections. The grant is part of a $ 14 million research investment by the Federal Agency to protect agricultural animals from disease.
“Animal health is very important for farmers and pastoralists,” said Carrie Castil, director of NIFA. This research will help to better understand, diagnose, control and prevent diseases in agricultural animals.
According to veterinarian David Needle, scientists have differentiated between the types of bacteria that cause breast cancer in normal and organic dairy products. In 3% to 5% of cases of mastitis in organic farms, a specific bacterial group has been identified, but in normal farms, 35% to 45% of mastitis infections have been found. These findings have been consistent over the years and across government boundaries, and needles and associates believe that there may be a link between the spread of UHH and Cornell mastitis and the local microbiological differences between conventional and organic dairy products.
Needles and Associates NVDL Managing Director Robert Gibson, United Nations Hubbard Center, and Laura Goodman, Michael Stanhope and Paolo Moroni plan to genetically target bacteria from Cornell, New Hampshire, about 800 common and organic cows. York and Vermont. These sequences are combined with the sequence of sample samples of the barn floor of the participating farms.
There is limited information about the general genomes of the pathogens that cause the infection, and there are large gaps in our understanding of bacteria and how or why they cause the disease. Bacterial genomic information is fundamental to understanding bacteria as pathogens – any bacterial pathogenesis or resistance to disease depends on the presence of specific genes that give these abilities. These genetic differences may be related to differences in management and medical practices in dairy farms. If the researchers identified a link between management and medical practice and the more or less aggressive genetic makeup of bacteria caused by breastfeeding, there may be more targeted and specific management and treatment approaches to reducing the incidence and severity of mastitis.
“We can learn from this that producers and veterinarians can reduce the incidence and severity of mastitis in conventional and organic dairy farms, thus increasing milk quality and milk production to include healthier and more comfortable cows, and increasing quality and longevity,” he said. Improves our understanding of bacterial evolution and how these bacteria change the health of dairy cows and the quality of their milk.
