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

A Review of Infectious and Non‐Infectious Causes of Pregnancy Loss in Goats

Reproduction in Domestic Animals, Volume 61, Issue 3, March 2026.
ABSTRACT Goats play a vital role in global agriculture, particularly in developing regions, and are increasingly kept as companion animals. Given their economic and social importance, pregnancy losses in goats represent a substantial challenge, leading to considerable economic losses and raising concerns about animal welfare and public health, as some ...

The Relationship Between Immunopathology and Body Condition of Mixed‐Age Ewes

New Zealand Journal of Agricultural Research, Volume 69, Issue 1, February 2026.
Ill thrift in ewes, characterised by less than desirable body condition, is a multifactorial condition often attributed to nutritional deficits, though immunopathological factors may also play a role. This study investigated associations between body condition scores (BCS) and immunopathological states in 120 mixed‐age ewes grazing pasture over 4 ...

A Multivalent Mannheimia-Bibersteinia Vaccine Protects Bighorn Sheep against Mannheimia haemolytica Challenge

Clinical and Vaccine Immunology, 2011
ABSTRACTBighorn sheep (BHS) are more susceptible than domestic sheep (DS) toMannheimia haemolyticapneumonia. Although both species carryM. haemolyticaas a commensal bacterium in the nasopharynx, DS carry mostly leukotoxin (Lkt)-positive strains while BHS carry Lkt-negative strains.

Comparative analysis of multiple inducible phages from Mannheimia haemolytica [PDF]

BMC Microbiology, 2015
Mannheimia haemolytica is a commensal bacterium that resides in the upper respiratory tract of cattle that can play a role in bovine respiratory disease. Prophages are common in the M. haemolytica genome and contribute significantly to host diversity.

Sudden death in a ewe due to Enterococcus hirae septicaemia

Veterinary Record Case Reports, Volume 14, Issue 1, February 2026.
Abstract A 2‐year‐10‐month‐old ewe, found dead 10 days post‐lambing, was submitted for postmortem examination to the Royal Veterinary College. Significant gross findings included subcutaneous and pleural haemorrhages, cortical renal haemorrhages, hydropericardium and a mural haemorrhagic thrombus in the right ventricular wall.

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

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.
