Haemophilus pittmaniae was described in 2005 as a new species distantly related to Haemophilus parainfluenzae. This member of the human saliva microbiota has also been further isolated from various body fluids without formal description of the patients.
We report the case of H. pittmaniae isolate made from a sputum specimen collected from a 58-year-old Caucasian man with a massive fibrotic form of siderosis who was awaiting lung transplantation. Identification of the isolate was ascertained by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and 16S rRNA gene sequencing. H. pittmaniae was considered to be responsible for the worsening of the patient’s chronic respiratory failure and was successfully treated with oral amoxicillin.
H. pittmaniae should be regarded as a new pathogen responsible for respiratory tract infection in patients with chronic lung diseases.
