HAEMOPHILUS PARAPHROPHILUS PDF

The aim of this study was to reinvestigate the relationships and the generic affiliations of the species Actinobacillus actinomycetemcomitans, Haemophilus aphrophilus, Haemophilus paraphrophilus and Haemophilus segnis. The nicotinamide phosphoribosyltransferase gene nadV conferring V factor-independent growth was identified in Haemophilus aphrophilus. The gene encodes a polypeptide of amino acids that shows Ten isolates of Haemophilus paraphrophilus all carried a nadV pseudogene. The transformants carried a full-length nadV inserted in the former locus of the pseudogene. We conclude that the division into two species Haemophilus aphrophilus and Haemophilus paraphrophilus is not justified and that Haemophilus paraphrophilus should be considered a later heterotypic synonym of Haemophilus aphrophilus.

The aim of this study was to reinvestigate the relationships and the generic affiliations of the species Actinobacillus actinomycetemcomitans, Haemophilus aphrophilus, Haemophilus paraphrophilus and Haemophilus segnis. The nicotinamide phosphoribosyltransferase gene nadV conferring V factor-independent growth was identified in Haemophilus aphrophilus.

The gene encodes a polypeptide of amino acids that shows Ten isolates of Haemophilus paraphrophilus all carried a nadV pseudogene. The transformants carried a full-length nadV inserted in the former locus of the pseudogene. We conclude that the division into two species Haemophilus aphrophilus and Haemophilus paraphrophilus is not justified and that Haemophilus paraphrophilus should be considered a later heterotypic synonym of Haemophilus aphrophilus.

Forty strains of Actinobacillus actinomycetemcomitans, Haemophilus aphrophilus and Haemophilus segnis were investigated by multilocus sequence analysis. The 40 strains form a monophyletic group clearly separate from other evolutionary lineages of the family Pasteurellaceae.

We propose the transfer of Actinobacillus actinomycetemcomitans, Haemophilus aphrophilus and Haemophilus segnis to a new genus Aggregatibacter gen. The species of the genus Aggregatibacter are independent of X factor and variably dependent on V factor for growth in vitro. This site needs JavaScript to work properly.

Haemophilus paraphrophilus

Many clinical laboratories have difficulty in identifying a group of organisms which are catalase negative, oxidase positive, Gram negative rods. We describe a case of purulent sacroiliitis due to Haemophilus paraphrophilus where the organism was initially misidentified as Eikenella corrodens leading to inappropriate antimicrobial chemotherapy. We review the strains of H. Only 21 of strains identified as E. Seven strains submitted as possible E. Several different species of Gram negative rods may produce pitting on agar and this seems to be poorly recognised. However, further tests are available to facilitate correct identification of these strains.
