ABSTRACT
<p><b>OBJECTIVE</b>To study the in vitro antibacterial activity of cefdinir against clinical isolates of respiratory tract pathogens in Children.</p><p><b>METHODS</b>MIC values of cefdinir against 380 strains were determined with E-test method and compared with those of cefaclor.</p><p><b>RESULTS</b>All penicillin-susceptible Streptococcus pneumoniae (PSSP) strains were also susceptible to cefdinir and cefaclor. Both cefdinir and cefaclor were not active against penicillin-resistant SP (PRSP). Against penicillin-intermediate SP (PISP) the susceptibility rates of cefdinir and cefaclor were 70.1% and 57.4%, respectively. The activity of cefdinir and cefaclor against beta-lactamases negative Hemophilus influenzae (HI) was excellent, but the susceptibility rates of cefdinir and cefaclor against beta-lactamases positive HI were 85.0% and 70.0%, respectively with MIC(90) of 1.5 mg/L vs. 256.0 mg/L. Cefdinir presented higher activities and lower MIC values than cefaclor against Moraxella catarrhalis (MC), Group A streptococcus (GAS), methicillin susceptible staphylococcus aureus (MSSA), and extended spectrum beta-lactamases (ESBLs) negative Escherichia coli (E. coli) or Klebsiella pneumoniae (K. pn). Both cefdinir and cefaclor were not susceptible to ESBLs positive E. coli and K. pn.</p><p><b>CONCLUSIONS</b>Cefdinir exhibits excellent activity against PSSP, PISP, HI, as well as MC, GAS, MSSA and ESBLs negative E. coli or K. pn.</p>
