In vitro bactericidal activities of a new oral cephalosporin, E1100, and morphologic changes on Escherichia coli.
Escherichia coli is one of the most common aerobic bacteria in pelvic inflammatory diseases. Oral cephalosporins have been widely used against those infections. We investigated in vitro morphologic changes induced on E. coli by a new oral cephalosporin, E1100, and its bactericidal activity on this organism. Morphologic changes were observed by electron microscopy. E1100 induced morphologic changes (filamentation) and exerted a bactericidal activity on E. coli. The filamentation induced by E1100 was time and concentration dependent.
