Abstract:
... Mannheimia haemolytica is an important cause of bovine respiratory disease (BRD). BRD is usually a multifactorial disease with host factors and viral infections influencing pathogenesis. Previous studies that have attempted to experimentally induce pneumonia using aerosolized M. haemolytica alone have produced inconsistent results, yet an aerosol model would be useful to study the details of early ...

Abstract:
... Ovine pneumonia is an economic important disease worldwide for the sheep industry. Multiple serotypes (S) of Mannheimia haemolytica are involved in the disease and S2 and S1 are the most frequent isolates associated with lung lesions in sheep. Vaccines based on some M. haemolytica S2 strains have been shown to have poor immunogenicity. The objective of this study was to determine the cross-protect ...

Abstract:
... Mannheimia haemolytica causes pneumonia in both bighorn sheep (BHS, Ovis canadensis) and domestic sheep (DS, Ovis aries). Under experimental conditions, co-pasturing of BHS and DS results in fatal pneumonia in BHS. It is conceivable that certain serotypes of M. haemolytica carried by DS are non-pathogenic to them, but lethal for BHS. M. haemolytica serotypes A1 and A2 are carried by DS in the naso ...

Abstract:
... Vaccination against Mannheimia haemolytica is a routine procedure in sheep farming, being repeatedly performed on the recommendations of commercial veterinary manufacturers or due to outbreaks of respiratory disease. However, the consequences of repeat vaccination after a short period, using live vaccines or culture supernatant (CS), have not been established, and its benefits are unknown. This st ...

A strain of Pasteurella trehalosi serotype 10, ECO-100, isolated from a bighorn sheep that had succumbed to pneumonic pasteurellosis during an epizootic, was compared to well-characterized strains of P. trehalosi serotype 10 and Mannheimia haemolytica serotype 1. The gene for leukotoxin A (lktA) from ECO-100 was sequenced and found to be identical on an amino acid basis to a published sequence for ...
