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

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

Essential oil from gum of Pistacia atlantica Desf.: Screening of antimicrobial activity

The essential oil from the gum of Pistacia atlantica Desf. grown in Algeria was obtained by the hydrodistillation method; and its antimicrobial activities against the growth of clinical isolates of Staphylococcus aureus; Escherichia coli and Streptococcus pyogenes were evaluated using three different methods; agar disc diffusion and dilution broth methods and minimum inhibitory concentration (MIC) which was subsequently; determined. The results of the study revealed that essential oil resin of P. atlantica has antimicrobial activity against gram-positive and -negative bacteria which are resistant to commonly used antimicrobial agents; and they were considerably dependent on concentration
