. Cephalosporins, e.g., cefaclor (Ceclor), act against both gram-positive and gram-negative bacteria (see Gram's stain Gram's stain, laboratory staining technique that distinguishes between two groups of bacteria by the identification of differences in the structure of their cell walls.

) by inhibiting bacterial cell wall synthesis. They are widely used to treat gonorrhea, meningitis, and staphylococcal and streptococcal infections in patients who cannot use penicillin. Overuse of cephalosporins has led to increased bacterial resistance to the drugs (see drug resistance drug resistance, condition in which infecting bacteria can resist the destructive effects of drugs such as antibiotics and sulfa drugs. Drug resistance has become a serious public health problem, since many disease-causing bacteria are no longer susceptible to

To the Editor: In the United States most third-generation cephalosporin resistance among salmonellae is due to AmpC plasmid-mediated [beta]-lactamases.
In our hospital, the third-generation cephalosporins do not adequately cover the Gramnegative organisms likely to be encountered.
Due to their ability to penetrate the central nervous sxstem, third-generation cephalosporins - except cefoperazone and cefixime - can be used to treat meningitis, including meningitis caused by pneumococci, meningococci, H influenzae, and susceptible gram-negative rods (bacillary infections of alimentary system).
