A species of gram-negative, facultatively anaerobic, rod-shaped bacteria normally commensal in the flora of CATTLE and SHEEP. But under conditions of physical or PHYSIOLOGICAL STRESS, it can cause MASTITIS in sheep and SHIPPING FEVER or ENZOOTIC CALF PNEUMONIA in cattle. Its former name was Pasteurella haemolytica.
Infections with bacteria of the family PASTEURELLACEAE.
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.
Bovine respiratory disease found in animals that have been shipped or exposed to CATTLE recently transported. The major agent responsible for the disease is MANNHEIMIA HAEMOLYTICA and less commonly, PASTEURELLA MULTOCIDA or HAEMOPHILUS SOMNUS. All three agents are normal inhabitants of the bovine nasal pharyngeal mucosa but not the LUNG. They are considered opportunistic pathogens following STRESS, PHYSIOLOGICAL and/or a viral infection. The resulting bacterial fibrinous BRONCHOPNEUMONIA is often fatal.
Chronic endemic respiratory disease of dairy calves and an important component of bovine respiratory disease complex. It primarily affects calves up to six months of age and the etiology is multifactorial. Stress plus a primary viral infection is followed by a secondary bacterial infection. The latter is most commonly associated with PASTEURELLA MULTOCIDA producing a purulent BRONCHOPNEUMONIA. Sometimes present are MANNHEIMIA HAEMOLYTICA; HAEMOPHILUS SOMNUS and mycoplasma species.
A species of sheep, Ovis canadensis, characterized by massive brown horns. There are at least four subspecies and they are all endangered or threatened.
A species of gram-negative bacteria (currently incertae sedis) causing multisystem disease in CATTLE.
A species of gram-negative, facultatively anaerobic, rod-shaped bacteria normally found in the flora of the mouth and respiratory tract of animals and birds. It causes shipping fever (see PASTEURELLOSIS, PNEUMONIC); HEMORRHAGIC BACTEREMIA; and intestinal disease in animals. In humans, disease usually arises from a wound infection following a bite or scratch from domesticated animals.
A family of coccoid to rod-shaped nonsporeforming, gram-negative, nonmotile, facultatively anaerobic bacteria that includes the genera ACTINOBACILLUS; HAEMOPHILUS; MANNHEIMIA; and PASTEURELLA.
Infections with bacteria of the genus PASTEURELLA.
A multifactorial disease of CATTLE resulting from complex interactions between environmental factors, host factors, and pathogens. The environmental factors act as stressors adversely affecting the IMMUNE SYSTEM and other host defenses and enhancing transmission of infecting agents.
Toxins produced, especially by bacterial or fungal cells, and released into the culture medium or environment.
Diseases of domestic and mountain sheep of the genus Ovis.
Diseases of domestic cattle of the genus Bos. It includes diseases of cows, yaks, and zebus.
A species of gram-negative bacteria causing MASTITIS; ARTHRITIS; and RESPIRATORY TRACT DISEASES in CATTLE.
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.
INFLAMMATION of the BREAST, or MAMMARY GLAND.
A species of PESTIVIRUS causing systemic infections (BOVINE VIRUS DIARRHEA-MUCOSAL DISEASE) in cattle and some other cloven-hoofed animals. There are several strains and two biotypes: cytopathic (rare) and non-cytopathic. Infections range from clinically inapparent to severe, but do not correlate with biotypes.
An alpha-integrin subunit found on lymphocytes, granulocytes, macrophages and monocytes. It combines with the integrin beta2 subunit (CD18 ANTIGEN) to form LYMPHOCYTE FUNCTION-ASSOCIATED ANTIGEN-1.
A specific streptogramin group B antibiotic produced by Streptomyces graminofaciens and other bacteria.
Inflammation of the lung parenchyma that is caused by bacterial infections.
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.
Cell-surface glycoprotein beta-chains that are non-covalently linked to specific alpha-chains of the CD11 family of leukocyte-adhesion molecules (RECEPTORS, LEUKOCYTE-ADHESION). A defect in the gene encoding CD18 causes LEUKOCYTE-ADHESION DEFICIENCY SYNDROME.
Immunoglobulins produced in a response to BACTERIAL ANTIGENS.
Suspensions of attenuated or killed bacteria administered for the prevention or treatment of infectious bacterial disease.
Either of the pair of organs occupying the cavity of the thorax that effect the aeration of the blood.
Inflammation of the lung parenchyma that is associated with BRONCHITIS, usually involving lobular areas from TERMINAL BRONCHIOLES to the PULMONARY ALVEOLI. The affected areas become filled with exudate that forms consolidated patches.
Proteins isolated from the outer membrane of Gram-negative bacteria.
Deoxyribonucleic acid that makes up the genetic material of bacteria.
The oldest recognized genus of the family PASTEURELLACEAE. It consists of several species. Its organisms occur most frequently as coccobacillus or rod-shaped and are gram-negative, nonmotile, facultative anaerobes. Species of this genus are found in both animals and humans.
The medical science concerned with the prevention, diagnosis, and treatment of diseases in animals.
Drugs used by veterinarians in the treatment of animal diseases. The veterinarian's pharmacological armamentarium is the counterpart of drugs treating human diseases, with dosage and administration adjusted to the size, weight, disease, and idiosyncrasies of the species. In the United States most drugs are subject to federal regulations with special reference to the safety of drugs and residues in edible animal products.
Use for general articles concerning veterinary medical education.
Suspensions of killed or attenuated microorganisms (bacteria, viruses, fungi, protozoa), antigenic proteins, synthetic constructs, or other bio-molecular derivatives, administered for the prevention, amelioration, or treatment of infectious and other diseases.
A board-certified specialty of VETERINARY MEDICINE, requiring at least four years of special education, training, and practice of veterinary surgery after graduation from veterinary school. In the written, oral, and practical examinations candidates may choose either large or small animal surgery. (From AVMA Directory, 43d ed, p278)
Educational institutions for individuals specializing in the field of veterinary medicine.
Vaccines in which the infectious microbial nucleic acid components have been destroyed by chemical or physical treatment (e.g., formalin, beta-propiolactone, gamma radiation) without affecting the antigenicity or immunogenicity of the viral coat or bacterial outer membrane proteins.
