Purification and biochemical properties of a bacteriocin from Actinobacillus actinomycetemcomitans.
Extracts of certain strains of Actinobacillus actinomycetemcomitans are inhibitory to strains of Streptococcus sanguis such as S. sanguis ATCC 10556. The isolation of a protein from an A. actinomycetemcomitans sonic extract which copurified with the inhibitory activity was accomplished by preparative isoelectric focusing, Sephadex G-100 gel filtration chromatography, and preparative polyacrylam...
متن کاملIsolation of Actinobacillus lignieresii and Actinobacillus equuli from laboratory rodents.
Actinobacillus lignieresii and Actinobacillus equuli were cultured from a total of 36 guinea pigs, rats, and mice. The organisms were isolated from the oropharynx, the conjunctiva, and middle ear. Isolates were initially screened by eight biochemical tests to determine whether they were of the genus Actinobacillus. Actinobacillus spp. were then differentiated by fermentation reactions of nine c...
متن کاملIsolation and characterization of hemolytic genes from Actinobacillus actinomycetemcomitans.
Periodontopathic Actinobacillus actinomyceremcomitans produces hemolysin and other leukotoxins. In the present study, two distinct clones which lysed horse erythrocytes were isolated by screening genomic DNA libraries of A. actinomycetemcomitans ATCC 43718 on blood agar plates. DNA hybridization analysis indicates that there were two distinct hemolytic genes present. Sonicated extracts from bot...
متن کاملPrevalence and Characterization of Actinobacillus pleuropneumoniae Isolated from Korean Pigs
Actinobacillus pleuropneumoniae causes porcine pleuropneumoniae which is one of severe threats to the swine industry. In total, 54 strains of Actinobacillus pleuropneumoniae were isolated from 443 pigs between 2012 and 2013 in Korea. Isolates were classified into serotypes 1, 2, 5, 7, 12, and unclassified by multiplex PCR. Genotypes of isolates were divided into three groups according to the se...
متن کاملActinobacillus minor sp. nov., Actinobacillus porcinus sp. nov., and Actinobacillus indolicus sp. nov., three new V factor-dependent species from the respiratory tract of pigs.
The results of DNA-DNA relatedness experiments and comparisons of sequences of genes coding for 16S rRNA were used to determine the genetic relationships of selected V factor-dependent species belonging to the family Pasteurellaceae and obtained from the porcine respiratory tract. These results showed that the Minor group and taxa C, D plus E, and F are distinct phylogenetic groups that are sep...
