PEPTIDE ENGINEERING FOR DEVELOPMENT OF ANTIMICROBIALS AGAINST Mannheimia haemolytica
Mannheimia haemolytica (M. haemolytica)-induced bovine respiratory disease causes millions of dollars in economic losses to Canadian cattle industry. Contemporary management strategies built around the use of antimicrobials are proving to be increasingly unavailing and lead to drug residues in meat …

Characterization of the genetic diversity and antimicrobial resistance in Mannheimia haemolytica from feedlot cattle
Mannheimia haemolytica is an opportunistic pathogen in cattle and the main bacterial agent in bovine respiratory disease. Despite its economic importance, few studies have characterized the genetic diversity of M. haemolytica, particularly from feedlots. Three genotyping techniques (BOX-PCR, …

Agent-based modeling to address emerging threats from antimicrobial resistance to the sustainability of the beef industry
… (TMS) and tetracycline was assessed in both M. haemolytica and E. coli. Three different on-arrival metaphylaxis options were considered, including oxytetracycline, tulathromycin or no drugs administered. Resistance prevalence was lower for antimicrobials specifically used to treat BRD following …

The role of inflammatory factors in the pathogenesis of Mycoplasma bovis pneumonia
… macrophages activated with Mannheimia haemolytica lysate and infected with different M. bovis strains. The in vivo experiment aimed to develop an improved animal model for the study of M. bovis pathogenesis and to evaluate the effects of different inflammatory stimuli on the development …

A MULTIMODAL CLINICAL AND DIAGNOSTIC APPROACH TO BOVINE RESPIRATORY DISEASE COMPLEX (BRDC) IN DAIRY CALVES
… evaluated. Pasteurella multocida and Mannheimia haemolytica were found in 37% and 12% of the samples, respectively, with a prevalence of 70% and 40% of the farms examined. The presence of Mycoplasma bovis was detected in 20% of the farms with a prevalence of 13% of the tested population. The …
