Mastitis, a potentially fatal mammary gland infection, is the most common disease in dairy cattle in the United States and worldwide. It is also the most costly disease to the dairy industry. [1] Milk from cows suffering from mastitis has an increased somatic cell count. Prevention and control of mastitis requires consistency in sanitizing the ...
Mastitis occurs in other animals as in humans, and is especially a concern in livestock, since milk from the affected udders of livestock may enter the food supply and pose a health risk. It is a major condition in some species, like dairy cows. It is the cause of much unwanted suffering for the dairy cows.
Mastitis has cost American dairy industries an estimated $1.5 to 2 billion per year in treating dairy cows. [33] In 1994, an EU scientific commission was asked to report on the incidence of mastitis and other disorders in dairy cows and on other aspects of their welfare. [16]
Since the outbreak in cows was announced in late March, bird flu has been detected in 33 dairy herds in nine states: Colorado, Idaho, Kansas, Michigan, New Mexico, North Carolina, South Dakota ...
Wyoming Game and Fish is reporting that the North American pronghorn is now affected by the disease with very high mortality. Mycoplasma bovis causes a constellation of diseases, including mastitis in dairy cows, arthritis in cows and calves, pneumonia in calves, and various other diseases likely including late-term abortion. Not all infected ...
The virus was detected in unpasteurized, clinical samples of milk, and swabs and tissue samples collected for diagnosis of sick cattle on dairy farms, the FDA reported.
The number of somatic cells increases in response to pathogenic bacteria like Staphylococcus aureus, a cause of mastitis. The SCC is quantified as cells per milliliter. General agreement rests on a reference range of less than 100,000 cells/mL for uninfected cows and greater than 250,000 for cows infected with significant pathogen levels.
Corynebacterium bovis is a pathogenic bacterium that causes mastitis and pyelonephritis in cattle.. C. bovis is a facultatively anaerobic, Gram-positive organism, characterized by nonencapsulated, nonsporulated, immobile, straight or curved rods with a length of 1 to 8 μm and width of 0.3 to 0.8 μm, which forms ramified aggregations in culture (looking like "Chinese characters").
