Haemophilus influenzae and Streptococcus pneumoniae in children with acute respiratory infection.
The incidence of Haemophilus influenzae and Streptococcus pneumoniae in children with acute respiratory infection (ARI) under 5 years was carried out by throat swab culture, blood culture, body fluid or tissue culture in 688 patients from a community, 744 patients from a teaching hospital in Bangkok, 766 normal children from the community and 303 children from a hospital well baby clinic. H. influenzae was found in the throats of 15-20% of patients and in the throats of 4-6% of normal children (p less than 0.001 for both hospital and community patients). Only 12/332 strains (3.6%) of H. influenzae were type b. The rest of H. influenzae were non type b. The most common biotype of H. influenzae non type b was biotype II. S. pneumoniae was found in hospital patients in highly significant numbers compared to the controls (12% vs 4%). No significant difference was observed in strains from the community patients.
