WebChloramphenicol tuh obat typus yang aku tau, dia bersifat bakteriostatik. Yang bekerja pada proses sistesis protein, dengan mengikat ribosomChloramphenicol (kloramfenikol) merupakan antibiotik yang menghambat enzim peptidil transferase sehingga menghambat sintesis protein kuman. The most serious side effect of chloramphenicol treatment is aplastic anaemia. This effect is rare but sometimes fatal. The risk of AA is high enough that alternatives should be strongly considered. Treatments are available but expensive. No way exists to predict who may or may not suffer this side effect. The effect usually occurs weeks or months after treatment has been stopped, and a genetic predisposition may be involved. It is not known whether monitoring the bl…

WebChloramphenicol is bacteriostatic but may be bactericidal in high concentrations or when used against highly susceptible organisms. Chloramphenicol stops bacterial growth by binding to the bacterial ribosome (blocking peptidyl transferase) and inhibiting protein synthesis. Mechanism of action WebJul 9, 1990 · High level bacterial resistance to chloramphenicol is generally due to O-acetylation of the antibiotic in a reaction catalysed by chloramphenicol acetyltransferase (CAT, EC 2.3.1.28) in which acetyl-coenzyme A is the acyl donor.
