Mastitis: INFLAMMATION of the BREAST, or MAMMARY GLAND.Mastitis, Bovine: INFLAMMATION of the UDDER in cows.Milk: The white liquid secreted by the mammary glands. It contains proteins, sugar, lipids, vitamins, and minerals.DairyingCattle: Domesticated bovine animals of the genus Bos, usually kept on a farm or ranch and used for the production of meat or dairy products or for heavy labor.Mammary Glands, Animal: MAMMARY GLANDS in the non-human MAMMALS.Prototheca: A genus of achlorophyllic algae in the family Chlorellaceae, and closely related to CHLORELLA. It is found in decayed matter; WATER; SEWAGE; and SOIL; and produces cutaneous and disseminated infections in various VERTEBRATES including humans.Lactation: The processes of milk secretion by the maternal MAMMARY GLANDS after PARTURITION. The proliferation of the mammary glandular tissue, milk synthesis, and milk expulsion or let down are regulated by the interactions of several hormones including ESTRADIOL; PROGESTERONE; PROLACTIN; and OXYTOCIN.Sheep Diseases: Diseases of domestic and mountain sheep of the genus Ovis.Staphylococcal Infections: Infections with bacteria of the genus STAPHYLOCOCCUS.Staphylococcus aureus: Potentially pathogenic bacteria found in nasal membranes, skin, hair follicles, and perineum of warm-blooded animals. They may cause a wide range of infections and intoxications.Pasteurellaceae Infections: Infections with bacteria of the family PASTEURELLACEAE.Cattle Diseases: Diseases of domestic cattle of the genus Bos. It includes diseases of cows, yaks, and zebus.Streptococcus: A genus of gram-positive, coccoid bacteria whose organisms occur in pairs or chains. No endospores are produced. Many species exist as commensals or parasites on man or animals with some being highly pathogenic. A few species are saprophytes and occur in the natural environment.Lactation Disorders: Disturbances of MILK secretion in either SEX, not necessarily related to PREGNANCY.Staphylococcus: A genus of gram-positive, facultatively anaerobic, coccoid bacteria. Its organisms occur singly, in pairs, and in tetrads and characteristically divide in more than one plane to form irregular clusters. Natural populations of Staphylococcus are found on the skin and mucous membranes of warm-blooded animals. Some species are opportunistic pathogens of humans and animals.Goat Diseases: Diseases of the domestic or wild goat of the genus Capra.Streptococcal Infections: Infections with bacteria of the genus STREPTOCOCCUS.Corynebacterium pyogenes: A species of CORYNEBACTERIUM isolated from abscesses of warm-blooded animals.Mycoplasma Infections: Infections with species of the genus MYCOPLASMA.Cell Count: The number of CELLS of a specific kind, usually measured per unit volume or area of sample.Milk, HumanMycoplasma bovis: A species of gram-negative bacteria causing MASTITIS; ARTHRITIS; and RESPIRATORY TRACT DISEASES in CATTLE.Corynebacterium: A genus of asporogenous bacteria that is widely distributed in nature. Its organisms appear as straight to slightly curved rods and are known to be human and animal parasites and pathogens.Buffaloes: Ruminants of the family Bovidae consisting of Bubalus arnee and Syncerus caffer. This concept is differentiated from BISON, which refers to Bison bison and Bison bonasus.Mannheimia: Genus of bacteria in the family PASTEURELLACEAE, comprising multiple species that do not ferment trehalose. Species include MANNHEIMIA HAEMOLYTICA; M. glucosida, M. granulomatis, M. ruminalis, and M. varigena.Escherichia coli Infections: Infections with bacteria of the species ESCHERICHIA COLI.Coagulase: Enzymes that cause coagulation in plasma by forming a complex with human PROTHROMBIN. Coagulases are produced by certain STAPHYLOCOCCUS and YERSINIA PESTIS. Staphylococci produce two types of coagulase: Staphylocoagulase, a free coagulase that produces true clotting of plasma, and Staphylococcal clumping factor, a bound coagulase in the cell wall that induces clumping of cells in the presence of fibrinogen.Breast Feeding: The nursing of an infant at the breast.Sheep: Any of the ruminant mammals with curved horns in the genus Ovis, family Bovidae. They possess lachrymal grooves and interdigital glands, which are absent in GOATS.Puerperal Infection: An infection occurring in PUERPERIUM, the period of 6-8 weeks after giving birth.Cloxacillin: A semi-synthetic antibiotic that is a chlorinated derivative of OXACILLIN.Goats: Any of numerous agile, hollow-horned RUMINANTS of the genus Capra, in the family Bovidae, closely related to the SHEEP.Housing, AnimalNipples: The conic organs which usually give outlet to milk from the mammary glands.
