Haemophilus influenzae is a major human pathogen; Haemophilus ducreyi, a sexually transmitted pathogen, causes chancroid; six other Haemophilus species are among the normal microbiota of mucous membranes and only occasionally cause human disease. Haemophilus aphrophilus and Haemophilus paraphrophilus have been combined into a single new species Aggregatibacter aphrophilus; likewise, Haemophilus segnis is now a member of the Aggregatibacter genus (Table 18-1).
