Biological characterization of Actinobacillus species and Pasteurella ureae.
Forty-seven strains of Actinobacillus and eleven strains of Pasteurella urea were studied using 119 morphological, physiological and biochemical characters. The resulting data were subjected to numerical analysis using the complement of Gower's coefficient excluding negative matches. Clustering was by unweighted pair group average linkage. At distance level 0.30, seven phenons and five isolated strains (including one strain of "A. seminis ") were obtained. The seven phenons correspond to Actinobacillus lignieresii , A. suis, A. equuli , A. capsulatus, "A. salpingitidis ", Actinobacillus sp. (Ross) and P. ureae. The characteristics allowing identification of the seven phenons are tabulated.
