Construction and Characterization of an Acapsular Mutant of Mannheimia haemolytica A1 [PDF]

Infection and Immunity, 2002
ABSTRACT The nmaA and nmaB genes, which code for UDP-GlcNAc-2-epimerase and UDP-ManNAc-dehydrogenase, respectively, are involved in capsular polysaccharide biosynthesis in Mannheimia haemolytica A1. A chloramphenicol resistance (Cm r )

Investigation of antimicrobial susceptibility and resistance genes in mannheimia haemolytica isolates obtained from respiratory tracts

Medicine Science
The potential transfer of antimicrobial agent residues and resistance genes in foods between bacteria creates a significant risk for public health. This research was objectived to investigate the susceptibility of Mannheimia haemolytica isolates from the

Biocontainment measures to control Mycoplasma bovis transmission in pre‐weaning dairy calves: An evidence‐based approach

Veterinary Record Case Reports, Volume 14, Issue 1, February 2026.
Abstract Mycoplasma bovis is a key pathogen in the bovine respiratory disease complex, known for causing significant health issues in cattle. A dairy farm in Scotland faced a significant outbreak of bovine respiratory disease in pre‐weaning calves (0–60 days old) during the winter period. M. bovis was identified as the primary pathogen in this case due

Analysis of gene order data supports vertical inheritance of the leukotoxin operon and genome rearrangements in the 5' flanking region in genus Mannheimia

BMC Evolutionary Biology, 2007
Background The Mannheimia subclades belong to the same bacterial genus, but have taken divergent paths toward their distinct lifestyles. For example, M. haemolytica + M. glucosida are potential pathogens of the respiratory tract in the mammalian suborder

Isolation and Identification of Pasteurella Species From Pneumonic Cases of Ovine and Caprine in Selected Districts of Afar Region, Ethiopia

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
• The present study finding indicated that M. haemolytica is the predominant bacterium associated with pneumonic pasteurellosis in ovine and caprine in the study areas. • Goats were found to be significantly more susceptible than sheep. • This could suggest the need for developing a polyvalent vaccine incorporating M. haemolytica strains.

Single‐dose Pasteurella multocida and Histophilus somni autogenous vaccines administered at induction significantly improved feedlot cattle performance and profitability in Australia

Australian Veterinary Journal, Volume 104, Issue 1-2, Page 37-49, January-February 2026.
Background Bovine respiratory disease (BRD) is the most economically important disease affecting feedlot cattle. While viral pathogens are initiating agents, bacterial coinfections exacerbate disease severity. Vaccines for Pasteurella multocida and Histophilus somni are not commercially available in Australia.

Proximity-Dependent Inhibition of Growth of Mannheimia haemolytica by Pasteurella multocida [PDF]

Applied and Environmental Microbiology, 2012
ABSTRACTMannheimia haemolytica,Pasteurella multocida, andBibersteinia trehalosihave been identified in the lungs of pneumonic bighorn sheep (BHS;Ovis canadensis). Of these pathogens,M. haemolyticahas been shown to consistently cause fatal pneumonia in BHS under experimental conditions. However,M.

Gallibacterium anatis Emerging in Indonesia: Isolation and Molecular Characterization From Chickens in a West Java Poultry Farm

Veterinary Medicine International, Volume 2026, Issue 1, 2026.
Gallibacterium anatis (G. anatis) is associated with decreased egg production and respiratory disorders in chickens. The presence of G. anatis in Indonesia has not been reported. This study aimed to identify G. anatis both phenotypically and genotypically in layer, broiler, and breeder chicken from farms in West Java.
