Efficacy of difloxacin in calves experimentally infected with Mannheimia haemolytica
American Journal of Veterinary Research, 2000Abstract Objective—To determine the efficacy of difloxacin, a novel fluoroquinolone antibiotic, in calves experimentally infected with Mannheimia haemolytica (formerly Pasteurella haemolytica). Animals—Seventy-two 3-month-old Holstein calves.

Effects of production practices on Mannheimia haemolytica
American Association of Bovine Practitioners Conference Proceedings, 2017Mannheimia haemolytica is a leading contributor to bovine respiratory disease (BRD). Various vaccines are available for prevention or control of BRD due to M. haemolytica; published research indicates that vaccines can decrease BRD morbidity. Several antimicrobials are labeled for treatment or control of BRD due to M. haemolytica.

Antimicrobial resistance in Mannheimia haemolytica: prevalence and impact
Animal Health Research Reviews, 2020AbstractBovine respiratory disease (BRD) is the most common cause of morbidity and mortality in North American beef cattle. In recent years, isolation of strains of Mannheimia haemolytica that are resistant to multiple different classes of antimicrobials has become commonplace.

Molecular genetic analysis of virulence in Mannheimia pasteurella haemolytica
Frontiers in Bioscience, 2001Mannheimia haemolytica (previously known as Pasteurella haemolytica) is a weakly hemolytic, gram-negative coccobacillus that is an opportunistic pathogen of cattle, sheep and other ruminants. In stressed, immunocompromised animals, the organism causes a fibrinous, necrotic pneumonia, commonly called "shipping fever".

[Mannheimia haemolytica and the pathogenesis of enzootic bronchopneumonia].
Berliner und Munchener tierarztliche Wochenschrift, 2004Mannheimia (M.) haemolytica (formerly Pasteurella [P.] haemolytica) is the primary aetiological agent of pneumonic pasteurellosis--one of the most important respiratory diseases in cattle and sheep. While bovine pneumonic pasteurellosis is regarded to be mainly caused by M.

Effects of Mannheimia haemolytica leukotoxin on apoptosis and oncosis of bovine neutrophils
American Journal of Veterinary Research, 2001Abstract Objective—To investigate the concentration-dependent effects of Mannheimia haemolytica (formerly Pasteurella haemolytica) leukotoxin (LKT) on apoptosis and oncosis in bovine neutrophils and to examine the role of calcium ions (Ca2+) in LKT-induced apoptosis. Sample Population—Neutrophils isolated from blood samples obtained

Serial progression of experimental Mannheimia haemolytica pneumonia
American Association of Bovine Practitioners Conference Proceedings, 2008Mannheimia haemolytica (MH) is a major pathogen of the bovine respiratory disease (BRD) complex. The objective of this study was to monitor various parameters of disease in beef feeder calves following experimental intrabronchial inoculation with MH.

Comparative pharmacokinetics of marbofloxacin in healthy and Mannheimia haemolytica infected calves
Research in Veterinary Science, 2007The pharmacokinetics of marbofloxacin were investigated in healthy (n=8) and Mannheimia haemolytica naturally infected (n=8) Simmental ruminant calves following intravenous (i.v.) and intramuscular (i.m.) administration of 2 mg kg(-1) body weight. The concentration of marbofloxacin in plasma was measured using high performance liquid chromatography ...

Genetic analysis of virulence factors of Mannheimia (Pasteurella) haemolytica A1
Veterinary Microbiology, 2001Using a molecular genetic approach, the genes that code for the various virulence factors of Mannheimia haemolytica A1 have been cloned for detailed characterizations. These included analysis of the encoded proteins, their biological activities, secretion of the molecules from the bacterium as well as their use in a vaccine component.
