  1. Haemophilus influenzae

    Haemophilus influenzae, formerly called Pfeiffer's bacillus or Bacillus influenzae, is a Gram-negative, coccobacilli bacterium first described in 1892 by Richard Pfeiffer during an influenza pandemic. A member of the Pasteurellaceae family, it is generally aerobic, but can grow as a facultative anaerobe. H. influenzae was mistakenly considered to be the cause of influenza until 1933, when the viral etiology of influenza became apparent. The bacterium is colloquially known as bacterial influenza. Still, H. influenzae is responsible for a wide range of clinical diseases. H. influenzae was the first free-living organism to have its entire genome sequenced. The sequencing project was completed and published in 1995.
