Genome Sequence of a Presumptive Mannheimia haemolytica Strain with an A1/A6-Cross-Reactive Serotype from a White-Tailed Deer (Odocoileus virginianus)

Mannheimia haemolytica is a Gram-negative bacterium and the principal etiological agent associated mostly with bovine respiratory disease complex. However, we report here the sequence of a strain with the novel A1/A6-cross-reactive serotype, strain PKL10, isolated from white-tailed deer. PKL10 was isolated from the spleen of farmed white-tailed deer showing clinical signs of pneumonia. The genome structure of PKL10 is dramatically different from that of previously sequenced isolates, which was demonstrated by genome alignments. In addition, the coding sequences in PKL10 share approximately 86% sequence identity with the coding sequences in other fully sequenced M. haemolytica strains. This suggests that PKL10 is a novel Mannheimia species.
