Cb. Gutierrez et al., CHARACTERIZATION OF V-FACTOR-DEPENDENT ORGANISMS OF THE FAMILY PASTEURELLACEAE ISOLATED FROM PORCINE PNEUMONIC LUNGS IN SPAIN, Comparative immunology, microbiology and infectious diseases, 16(2), 1993, pp. 123-130
116 V factor (NAD)-dependent strains belonging to the family Pasterure
llaceae isolated from porcine pneumonic lungs were collected in Spain
over a period of 1 yr and studied using 52 biochemical characters. In
addition to Actinobacillus pleuropneumoniae (72 strains), Haemophilus
taxon minor group (37 strains) and Taxon D (four strains), other taxon
(three strains) were observed. This taxon, provisionally designated a
s Haemophilus sp. sorbitol+, is closed to A. pleuropneunoniae but diff
ered by some biochemical characteristics. Among A. pleuropneumoniae st
rains, nine different serotypes were detected, the most frequent being
serotypes 4 and 2.
