Respiratory symptoms due to Branhamella catarrhalis and other Neisseria species infections--response to erythromycin therapy.
Neisseria microorganisms (Neisseria lactamica, Neisseria sicca, and Neisseria mucosa) are regarded as normal respiratory commensals. Branhamella catarrhalis (formerly Neisseria catarrhalis) has also been regarded as a normal respiratory commensal, but reports indicate that it can be pathogenic. The role of Neisseria spp was studied in 160 patients with chest infections and symptoms and signs of obstructive respiratory disease. Group I patients (n = 140) had a history of asthma, bronchitis, and emphysema. Group II patients (n = 20) had an initially responsive pulmonary tuberculosis but presented with fever and obstructive airway disease. Group I patients had disease that was difficult to control despite increased bronchodilator therapy, but they responded dramatically after two to three days of appropriate antibiotic therapy. Patients in group II showed a similar response to erythromycin. Neisseria infection was responsible for precipitating or exacerbating respiratory distress in both groups. Accordingly, it is concluded that Neisseria can be pathogenic and that patients with fever and obstructive respiratory symptoms require treatment.
