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.

Since the oxidase reaction was found to be positive, we identified the organism as H. The microorganism has been found as a member of normal oral and pharyngeal flora and, as noted above, can cause inflammatory processes, often with abscess formation, at various sites. 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.
