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.
