Chloramphenicol, also known as chlornitromycin, is a broad-spectrum, bacteriostatic antibiotic derived from Streptomyces venezuelae.It is effective against several gram-positive and gram-negative bacteria and commonly used in researching protein synthesis and to select for chloramphenicol-resistant transformed cells or the bacterial CAT gene.

Chloramphenicol functions by binding the 50s ribosomal subunit and inhibiting synthesis of proteins by blocking aminoacyl-tRNA from attaching to the A site.

Antibiotics are often used in clinical in vitro tests known as antimicrobial susceptibility tests or ASTs to determine their efficacy against certain bacterial species. They are tested against gram-negative and gram-positive bacteria using panels, discs, and MIC strips by medical microbiologists. ASTs decrease the risk of using an antibiotic against bacteria exhibiting resistance to it, and the results are used in clinical settings to determine which antibiotic(s) to prescribe for various infections.
