Dear Sir,
Streptococcus pneumoniae is a versatile human pathogen causing infectious disease ranging from mild infection (i.e. otitis media) to life therating pneumonia and meningitidis in many countries. [1] The research reports that, 92 capsular serotypes of Streptococcus pneumoniae differ greatly in nasopharyngeal carriage prevalence, invasiveness, and disease incidence. [2] Therefore, there has been some necessitate, though, regarding whether serotype independently affects the outcome of invasive pneumococcal disease (IPD). A total of 135 patients infected samples suspected of invasive streptococcal disease (IPD) were subjected to PCR and bacteriological methods. Out of which, 115 strains of S. pneumoniae was isolated and confirmed by PCR method. The results of this study showed some S. pneumoniae serotypes were found in both sexes and some only in one sex invasive infections. For example, serotypes 10, 14, 18 and 22 were only in female patients with infections. While serotypes 20 were only isolated from men infected. [7] The analysis of the results had suggested that serotypes 6 and 19 are the most abundant bacterial strains isolated from patients. Our data is different from other area research. For example, some studies were shown that, the serotypes 1 and 5 were commonly causing IPD. [3],[4],[5],[6],[7] Hence, the only vaccine that is able coverage serotypes our country is the 23- valent vaccine.
