Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence? Haemophilus influenzae is a non-motile Gram-negative coccobacillus first identifed by Dr. Robert Pfeiffer in 1892. the genome structure of haemophilus influenzae consist of 1,830,138 nucleotide base pairs and it is estimated to have approximately 1740 genes and was the first genome to be sequenced and assembled in a free living organism
