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.

Showing of 9 extracted citations. 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.

Ten isolates of Haemophilus paraphrophilus all carried a nadV pseudogene. Since the oxidase reaction was found to be positive, we identified the organism as H. Identification of Actinobacillus actinomycetemcomitans by leukotoxin gene-specific hybridization and polymerase chain reaction assays.
