Interpretive Summary: Mannheimia haemolytica is a costly bacterial causative agent of pneumonia (shipping fever) in cattle. This bacterium responds to stress and concurrent respiratory viral infection by greatly elevated levels of infection in cattle nasal passages. Although serotypes 1, 2, and 6 are common among in cattle nasal passages, only serotypes 1 and 6 so respond and that is likely why these latter serotypes predominate in pneumonic disease. Whole genome sequencing was conducted to define the differences between the serotypes. This report describes the genomes of two serotype 2 strains. Comparison of these with the genomes of serotypes 1 and 6 will allow scientists to focus on factors related to the stress response and potentially lead to improved disease intervention strategies.

Technical Abstract: Here we report two genomes, one complete and one draft, from virulent bovine strains of Mannheimia haemolytica(strains D174 and D38)serotype A2 recovered prior to the field usage of modern antimicrobial drugs.
