Mannheimia haemolytica biofilm formation on bovine respiratory epithelial cells

Veterinary Microbiology, 2016
Mannheimia haemolytica is the most important bacterial agent associated with the bovine respiratory disease complex (BRDC), which causes worldwide economic losses to the cattle industry. M. haemolytica cells initially colonize the tonsillar crypts in the upper respiratory tract of cattle, from where they can subsequently descend into the lungs to cause

Cross-Section Observational Study to Assess Antimicrobial Resistance Prevalence among Bovine Respiratory Disease Bacterial Isolates from Commercial US Feedlots

Antibiotics, 2023
Antimicrobial resistance (AMR) is a global public health threat that jeopardizes efficacy of antibiotics in veterinary and human medicine. Antibiotics are commonly administered to target the bacterial component of bovine respiratory disease (BRD).

Thoracic Ultrasonography in Calves: A Narrative Review of Techniques and Reporting Practices

Journal of Veterinary Internal Medicine, Volume 39, Issue 6, November/December 2025.
ABSTRACT Ultrasonography of the bovine lung is a noninvasive technique allowing recognition of lower respiratory tract lesions and differentiation from disease limited to the upper respiratory tract. Techniques for scanning the thorax have evolved to facilitate examination of cohorts of calves quickly, while maintaining accuracy. Classification systems

Construction and Characterization of Novel Shuttle Expression Vectors for Actinobacillus succinogenes

Biotechnology and Applied Biochemistry, Volume 72, Issue 5, Page 1265-1273, October 2025.
ABSTRACT Actinobacillus succinogenes is a ruminal microorganism of biotechnological importance due to its capacity to produce succinic acid at high yields. Despite the scientific interest in this organism, molecular vehicles for the transfer and expression of genetic material are limited compared to the existing demand.

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
