Antibiotic susceptibility of the bacterial pathogens isolated from acute respiratory patients

ABSTRACT

At the National Institute of Pediatrics, the cause of acute respiratory inflammation was studied. Most of pathogenic bacteria isolated from patients with pneumonia and bronchitis were S.pneumoniae (48%) and H.influenzae (44%). The methods using antibiotics dilution on agar to determine the minimum concentration of bacteria and PCR to determine the penicillin resistant gene sequences were used. Results showed that 58% of strains of S.pneumoniae were resistant to penicillin with a sensitivity 19%; 74% resistant to cefotaxin, sensitivity 16%. Other beta-lactamase antibiotics except ampicillin (resistance 35%, sensitivity 30%)
