Haemophilus Influenzae Biogroup Aegyptius - Relation To Hemophilus Influenza

Relation To Hemophilus Influenza

In 1892, Pfeiffer discovered H. influenzae, raising some confusion over whether H. aegyptius was different from H. influenzae. Debate has occurred for centuries. Pittman, who first gave this bacteria its modern name, felt that these bacteria had enough dissimilarities to be considered a separate species. Others, like Brenner et al. stand by a historical viewpoint that the two species are one and the same, with H. influenzae being the older name, and thus the name with higher priority. These bacteria are curious in that they are phylogenetically one species but differ phenotypically; they share the same historical pattern but have clinical differences. Today, the issue remains unresolved, although scientists have put in a lot of effort to classify this bacteria. So far, no one test standing alone has been able to differentiate these two bacteria; however, through compound efforts of different scientists and different tests scientists have gained a greater understanding of the relationship between these two bacteria. In order to account for both the similarities and differences, H. aegyptius has been classified as a biogroup of H. influenzae.
