Mannheimia haemolytica and respiratory complex diseases in calves

Practica Veterinara.ro, 2023
Mannheimia haemolytica, formerly known as Pasteurella haemolytica, is a bacterium belonging to the family Pasteurellaceae. It is commonly found in the respiratory tracts of cattle and other ruminant animals, and is a significant pathogen in the cattle industry.

Experimental infection of Peste des Petit Ruminant virus and Mannheimia haemolytica A2 in goats: immunolocalisation of Mannheimia haemolytica antigens

Veterinary Research Communications, 2010
Nigerian strain of Peste des Petit Ruminant (PPR) virus and Mannheimia haemolytica (MH) biotype A serotype 2, was used successfully to reproduce a concurrent disease in West African Dwarf goats. The development of the various pathological features were studied at regular intervals following infection. The acute inflammatory reaction which had developed

Investigations on the species specificity of Mannheimia (Pasteurella) haemolytica serotyping

Veterinary Microbiology, 1999
Eleven serotypes (1, 2, 5-9, 12-14 and 16) have been demonstrated within Mannheimia haemolytica. Subsequent serotyping of 166 Mannheimia haemolytica-like strains, genetically and phenotyphically distinct from Mannheimia haemolytica, and isolated from ruminants, pigs, hares and rabbits showed that 13.2% were typeable, 19 of which were serotype 11 ...

Construction and analysis of a Mannheimia haemolytica A1 luxS mutant

Veterinary Microbiology, 2005
Mannheimia haemolytica A1 is the causative agent of bovine pneumonic pasteurellosis, a major cause of sickness, death, and economic loss to the feedlot cattle industry. M. haemolytica A1 produces autoinducer-2 (AI-2) like molecules that are capable of inducing quorum sensing system 2 of Vibrio harveyi.

Mannheimia haemolytica leukotoxin

2010
Mannheimia haemolytica is the primary bacterial pathogen of bovine pneumonic pasteurellosis, an economically important disease of cattle worldwide. Leukotoxin (Lkt) produced by M. haemolytica is the major virulence factor of this organism. The cytolytic activity of Lkt is specific for ruminant leukocytes.

Efficacy of difloxacin in calves experimentally infected with Mannheimia haemolytica

American Journal of Veterinary Research, 2000
Abstract 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, 2017
Mannheimia 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.

Molecular genetic analysis of virulence in Mannheimia pasteurella haemolytica

Frontiers in Bioscience, 2001
Mannheimia 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".

Antimicrobial resistance in Mannheimia haemolytica: prevalence and impact

Animal Health Research Reviews, 2020
AbstractBovine 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.

Mannheimia haemolytica in bovine respiratory disease

Romanian Journal of Veterinary Sciences
Mannheimia haemolytica is a major bacterial pathogen in bovine respiratory disease (BRD), particularly in feedlot and intensively managed cattle. Although it colonizes the upper respiratory tract as a commensal, stress, viral infections, or co-infections allow it to invade the lungs, causing severe fibrinous pneumonia.
