ABSTRACT
Sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) applied to outer membrane protein (OMP), extracted by a micromethod, was employed to subtype H. influenza b type I. A total of 37 H. influenzae b strains were isolated from children under 4 years of age, either with lower acute respiratory infection (LARI), or asymptomatic carriers matched according sex, socioeconomic level and seasonality. Twenty seven out of the 37 H. influenzae b strains belonged to biotype I. On the basis of OMP profiles, these 27 were classified into 8 subtypes (Figs. 2, 3, 4 and 5). The probability of two randomly chosen isolates having different OMP profiles was 0.733. The subtype termed [quot ]a[quot ] showed the greatest relative frequency and was detected both in invasive strains and in those isolated from throat samples of LARI cases and healthy children.
