Serological Investigation of Major Respiratory Viruses in Sheep in North Shewa, Ethiopia: Parainfluenza Virus, Bluetongue Virus, Maedi‐Visna Virus and Peste des Petits Ruminants Virus

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
• High exposure to respiratory viruses in sheep • PI‐3 predominated, followed by PPRV, BTV and MVV • Mixed viral exposure was common, indicating frequent pathogen co‐circulation • Integrated surveillance, vaccination and husbandry are needed ABSTRACT Background Respiratory diseases significantly affect small ruminants, leading to considerable illness ...

Trueperella pyogenes–Associated Acute Pneumonia in Korean Native Calves

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
Trueperella pyogenes can cause a wide range of suppurative infections, including urogenital and mammary infections, liver abscesses and pneumonia. This case report demonstrates Trueperella pyogenes as a primary cause of bovine respiratory disease in Korean native calves.

Comparative Genomic Analysis of Mannheimia haemolytica from Bovine Sources

PLOS ONE, 2016
Bovine respiratory disease is a common health problem in beef production. The primary bacterial agent involved, Mannheimia haemolytica, is a target for antimicrobial therapy and at risk for associated antimicrobial resistance development. The role of M.

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.

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

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

Diagnosis, management and prevention of umbilical infections in bovine youngstock

In Practice, Volume 48, Issue 3, Page 119-126, April 2026.
Background: Umbilical infections in calves demonstrate varied presentations, ranging from subclinical to localised swellings to more severe, disseminated infections, with or without associated umbilical hernias. Hygiene is a key modifiable risk factor – good management practices are central to prevention.

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.

Advancing management of respiratory disease through thoracic ultrasound of bovine youngstock

In Practice, Volume 48, Issue 2, Page 78-84, March 2026.
Background: Bovine respiratory disease is the second most common cause of mortality in calves, resulting in significant reductions in growth rates as well as long‐term issues such as delays to age at first calving. It is also a leading cause of antimicrobial use in calves and a large time factor for farmers dealing with sick calves.

Transcriptomic profiles of Mannheimia haemolytica planktonic and biofilm associated cells. [PDF]

PLoS One
Mannheimia haemolytica is the principal agent contributing to bovine respiratory disease and can form biofilms with increased resistance to antibiotic treatment and host immune defenses. To investigate the molecular mechanisms underlying M. haemolytica biofilm formation, transcriptomic analyses were performed with mRNAs sequenced from planktonic and ...
