Abstract
Findings in specimens from the lower respiratory tract of children were reviewed retrospectively in order to assess the rate of Branhamella catarrhalis and beta-lactamase production. B. catarrhalis was isolated in 139 of 756 samples (18.4%) in 1986 and 211 of 723 samples (29.2%) in 1989. Beta-lactamase production was found in 55.6% of B. catarrhalis strains in 1986 and 80.1% in 1989 (p less than 0.001). Prevalence of beta-lactamase in B. catarrhalis has now reached the same level in Europe as in the USA.Entities:
