“…This observation indicates that chronic pulmonary diseases are an important determinant risk factor of lower respiratory tract infection due to B. catarrhalis. McLeod (1983) and others (Ninane et al 1978 ;Johnson et al 1981;Slevin et al 1984) have also isolated this bacterium mainly in sputa of patients with chronic pulmonary diseases. However, B. catarrhalis adherence to oropharyngeal cells did not depend on the type of the underlying pulmonary disease.…”

“…Other investigators (Ninane et al 1978;Johnson et al 1981; Aitken and Thornley 1983;McLeod et al 1983; Slevin et al 1984) have also reported that B. catarrhalis has become an important pathogen of the lower respiratory tract and should no longer be regarded as a commensal. Nevertheless, the reason for such a rapid increase in incidence is not clearly understood.…”

Bacterial colonization of the oropharynx is the initial event in most lower respiratory tract infections. To study the role of bacterial adherence in lower respiratory tract infections caused by Branhamella catarrhalis (B. catarrhalis) in winter, in vitro adherence assays of the organism to human oropharyngeal cells were carried out in winter, spring, summer and autumn. A total of 57 adults of both sexes were studied from January to December 1985. Forty eight persons of 57 had chronic pulmonary diseases and the remaining 9 persons had other clinical entities and served as the control group. Predominance of lower respiratory tract infections caused by B. catarrhalis with high adherence rate was observed in winter. Adherence activity was moderate in spring and autumn and low in summer and accompanied by a similar incidence of lower respiratory tract infections with this bacteria. In addition, similar results were found in patients in whom investigations were done successively in the above four seasons. Bacterial adherence activity to cells however, was weak in winter in the control group. These results indicate that seasonal variation plays a significant role in the ability of B. catarrhalis to adhere to oropharyngeal cells. This is an important pathogenic factor correlated with the incidence of lower.respiratory tract infections in these patients.

“…Now B. catarrhalis is increasingly recognized as an important cause of respiratory tract infection secondary to underlying pulmonary disease (Ninane, Joly & Kraytman, 1978;McLeod et al 1983). Many recent isolates produce a beta-lactamase enzyme Ahmad et al 1984), and the ability of diagnostic laboratories to correctly identify B. catarrhalis has assumed some importance .…”

SUMMARYDuring a 3-year period Branhamella catarrhalis was isolated in significant numbers from 239 (1P3%) of 19488 specimens of sputum sent for routine microbiological examination at a 700-bed general hospital. The majority of patients (83 %) were over 60 years of age and 65 % were male. There was a distinct seasonal variation in isolations with a peak incidence during the winter and early spring, a pattern not found with other pathogens. Susceptibility to amoxycillin decreased by approximately 50 % over the 3 years, corresponding to an increased incidence of beta-lactamase-producing strains. There were minimal changes in susceptibility to other antimicrobial agents. Underlying pulmonary disease was the major factor predisposing to B. catarrhalis infection, and 71 % of patients were smokers or ex-smokers.

“…(i) By using strict criteria to evaluate the quality of sputum samples, a subset of patients with exacerbations of COPD have sputum smears which show a predominance of gram-negative diplococci on Gram strain and virtually pure cultures of B. catarrhalis (32,119,128,158,179). (ii) Pure cultures of B. catarrhalis have been obtained in transtracheal aspirates from patients experiencing exacerbations of COPD and pneumonia (7,47,80,130,184). (iii) Clinical improvement is seen in patients with B. catarrhalis infections following the administration of specific antibiotic therapy.…”
