In vitro susceptibility of selected bacteria to cefaclor.
Cefaclor is an orally absorbed cephalosporin antibiotic chemically and pharmacologically similar to cephalexin. It appears to be more active than cephalexin against susceptible strains. The in vitro sensitivity of 230 clinical bacterial isolates to cefaclor was studied. Most isolates of S. aureus, K. pneumoniae, E. coli, and indole negative Proteus species were inhibited at clinically attainable serum and urine concentrations. Like cephalexin, cefaclor was less active against isolates of Enterobacter species, indole positive Proteus species and enterococci although many of these isolates were inhibited at concentrations achievable in urine.
