Importance of bacterial resistance in Streptococcus pneumoniae and Streptococcus pyogenes in the center region in Cameroon

Abstract EN

Respiratory tract infections are a real public health problem, and the few studies of African data make difficult the definition of a probabilistic rational therapeutic approach.

The present study from May 2006 to June 2007 included 107 strains of Streptococcus pneumoniae and 94 strains of Streptococcus pyogenes.

A single isolate was collected by topic, and the minimum inhibitory concentration (MIC) has been made by the E test method; 201 strains from 115 adults and 86 children were included in the study.

From 107 strains of S.

pneumoniae, 24 were from children; and from 94 strains of S.

pyogenes, 62 came from child.

From antibiotics susceptibility of S.

pyogenes, 100% were sensitive to penicillin G, with MIC between 0.064 and 0.128; 20 were resistant to erythromycin; and 100% were sensitive to levofloxacin, chloramphenicol, amoxicillin, cefotaxime, and ceftriaxone.

From S.

pneumoniae, 95.3% were sensitive to penicillin G and 4.7% were intermediate; 19.3% were resistant to erythromycin; 100% were sensitive to levofloxacin, cefotaxime amoxicillin, and ceftriaxone.
