Cultural, morphologic, and biochemical characteristics of previously unreported taxa isolated from poultry and tentatively assigned to genus Actinobacillus Brumpt 1910 were compared to those of Actinobacillus lignieresii, A equuli, A. seminis, A. suis, avian haemolytic Actinobacillus sp., A.salpingitidis, avian Pasteurella haemolytica-like strains, P haemolytica biovar T, P, ureae. P. multocida, P. pneumotropica, P. gallinarum and P. anatipestifer. Evidence as obtained to indicate that taxon 1--3 was closely related to genus Actinobacillus Brumpt 1910, but sufficiently different from established species within that genus to constitute new distinct species. Taxon 4 had the cultural and biochemical characters of strains previously described by Clark and Godfrey. Strains designated P haemolytica-like could not be separated from A. salpingitidis on the basis of phenotypical characters. The final taxonomical position of taxon 1-4 in addition to strains designated avian haemolytic Actinobacillus sp. and P. haemolytica-like, however, has to await further taxonomical investigations including determination of mol % G + C in DNA and DNA hybridization, for which reason species names have been omitted.
