Antibiotics targeting the organism's cell wall are mostly bactericidal, whereas those targeting protein syntheses are bacteriostatic. By contrast, bactericidal drugs kill their target bacteria. Antibiotics can be divided to two groups on the basis of their effect on microbial cells through two main mechanisms, which are either bactericidal or bacteriostatic. These studies demonstrated that chloramphenicol, an antibiotic generally regarded as bacteriostatic, can in fact achieve bactericidal activity against Streptococcus pneumoniae and can achieve microbiologic cure rates comparable to that of ampicillin in the rabbit model of meningitis when mean peak CSF concentrations exceeded the minimum bactericidal concentration for the organism.
