Mannheimia haemolytica IgA-specific proteases

Veterinary Microbiology, 2019
Mannheimia haemolytica colonizes the nasopharynx of cattle and can cause severe fibrinous pleuropneumonia. IgA proteases are metalloendopeptidases released by bacteria that cleave IgA, enhancing colonization of mucosa. The objectives of these studies were to characterize M.

Characterization of Mannheimia haemolytica biofilm formation in vitro

Veterinary Microbiology, 2015
Mannheimia haemolytica is the primary bacterial agent in the bovine respiratory disease complex. It is thought that M. haemolytica colonizes the tonsillar crypts of cattle as a commensal and subsequently descends into the lungs to cause disease. Many bacterial species persist in the host as biofilms. There is limited information about the ability of M.

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.

Mannheimia haemolyticaand bovine respiratory disease

Animal Health Research Reviews, 2007
AbstractMannheimia haemolyticais the principal bacterium isolated from respiratory disease in feedlot cattle and is a significant component of enzootic pneumonia in all neonatal calves. A commensal of the nasopharynx,M. haemolyticais an opportunist, gaining access to the lungs when host defenses are compromised by stress or infection with respiratory ...

A multiplex polymerase chain reaction assay for the identification of Mannheimia haemolytica, Mannheimia glucosida and Mannheimia ruminalis

Veterinary Microbiology, 2008
The objective of this study was to design a multiplex PCR assay to identify Mannheimia haemolytica, Mannheimia glucosida and Mannheimia ruminalis. The multiplex PCR included primer sets HP, amplifying a DNA region from an unknown hypothetical protein, Lkt and Lkt2, amplifying different regions of the leukotoxinD gene, and 16S to amplify universal ...

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

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.
