title: Genetic relatedness of Haemophilus somnus to select genera of bacteria.
abstract: The degree of DNA homology from Haemophilus somnus and DNA from select members of the genera Haemophilus, Actinobacillus, Pasteurella, Escherichia, and Micrococcus was determined. Hybridization tests indicated that H somnus DNA has a 46%, 58%, and 43% homology with the DNA from H influenzae, H parainfluenzae, and A lignieresii, respectively. These percentages of homology values indicate that H somnus was moderately related to 2 members of the genus Haemophilus and 1 member of the genus Actinobacillus. Haemophilus somnus DNA did not show any hybridization with DNA from the genera of Escherichia, Micrococcus, or Pasteurella.
