It is not effective against Pseudomonas aeruginosa. Chloramphenical penetrates well into cerebrospinal fluid, and receives occasional usage for meningitis—especially when caused by H.

Resistance to chloramphenicol is mainly due to the production of a specific inactivating chloramphenicol acetyltransferase CAT. Tetracycline and derivatives Demeclocycline Chlortetracycline Oxytetracycline Tetracycline. Chloramphenicol and thiamphenicol inhibit bacterial protein synthesis and have bacteriostatic activity.

Chloramphenicol is a bacteriostatic agent that binds to the 50S ribosomal subunit. No way exists to predict who may or may not get this side effect. Superficial infections of the skin caused by susceptible bacteria.

It crosses the placenta well and can reach therapeutic concentrations in the fetus. Chloramphenicol palmitate and chloramphenicol sodium succinate must be hydrolyzed to chloramphenicol before antimicrobial activity can take place.

In gram-negative bacteria, resistance to chloramphenicol may also be due to reduced drug uptake mediated by chromosomal mutations or by acquired resistance genes. Resistance-conferring mutations of the 50S ribosomal subunit are rare.

Reversible, dose-related nonregenerative anemia can occur in dogs and cats. Pentamycetin, Chloromycetin, others [1]. Neonates who weigh more than 2 kg and are age 7 days and older: In dogs florfenicol is poorly absorbed after SC administration.
