Abstract. Human diseases caused by Haemophilus paraphrophilus (H. paraphrophilus) are unusual. The following case report describes a year-old man who. With Aggregatibacter aphrophilus, some isolates are dependent on V factor ( formerly Haemophilus paraphrophilus), while others are not (formerly Haemophilus. Actinobacillus actinomycetemcomitans, Haemophilus aphrophilus, transform Haemophilus paraphrophilus into the NAD-independent phenotype.

Our patient is a year old man with HIV and diet-controlled hyperlipidemia, who presented to the dental office with a chief complaint of pain and swelling over the right side of the face and below the right ear over 1 week. Joerg Graf Journal of clinical microbiology 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.

Arch Mal Coeur Vaiss. Serum antibody in Actinobacillus actinomycetemcomitans-infected patients with periodontal disease. The nicotinamide phosphoribosyltransferase gene nadV conferring V factor-independent growth was identified in Haemophilus aphrophilus. We propose the transfer of Actinobacillus actinomycetemcomitans, Haemophilus aphrophilus and Haemophilus segnis to a new genus Aggregatibacter gen. The growth was present on a chocolate agar plate.

Reclassification of Actinobacillus actinomycetemcomitans, Haemophilus aphrophilus, Haemophilus paraphrophilus and Haemophilus segnis as Aggregatibacter actinomycetemcomitans gen. From This Paper Figures, tables, and topics from this paper. 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.

Since the oxidase reaction was found to be positive, we identified the organism as H. Am J Med Sci.

A distinguishing reaction between these two organisms is the oxidase reaction that is positive for H. The species of the genus Aggregatibacter are independent of X factor and variably dependent on V factor for growth in vitro.

The patient was successfully treated with IV Unasyn and Bactrim for four days and then switched to oral Augmentin and Bactrim for another 10 days. To our knowledge, there was no evidence to support any similar associated condition in our patient, although HIV positivity implies immune deficiency that could have predisposed toward infection.
