Milk from cows suffering from mastitis has an increased somatic cell count. Prevention and control of mastitis requires consistency in sanitizing the cow barn facilities, proper milking procedure and segregation of infected animals. Treatment of the disease is carried out by penicillin injection in combination with sulphar drug.
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").
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 cows get sick – some shed the disease without becoming ill, allowing for transmission between farms if apparently healthy ...
The species can infect man and animal, causing mastitis. [3] P. zopfii can cause bovine clinical mastitis in high milk-yielding cows. [7] Genotypes I and III, traditionally, are thought not to be involved in the pathogenicity of mastitis and to be pollutants of milk, whereas genotype II is believed the main cause of mastitis. [3]
GBS is a major cause of mastitis (an infection of the udder) in dairy cattle and an important source of economic loss for the industry. GBS in cows can either produce an acute febrile disease or a subacute more chronic condition. Both lead to diminishing milk production (hence its name: agalactiae meaning "of no milk"). [69]
Although it can infect a wide variety of tissues, Trueperella pyogenes is the most common cause of "summer mastitis" in cattle and pyometra in dogs [citation needed].
It is one of the most common causes of mastitis in dairy cattle. [2] S. uberis KJ2 is put in oral probiotics and sold, the efficacy of this is contested. [3]
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.
