General description

Synthetic bacteriostatic antibiotic that inhibits the translation of RNA by blocking the peptidyltransferase reaction on ribosomes.
Synthetic bacteriostatic antibiotic that inhibits the translation of RNA to protein by binding to the 50S ribosomal subunit, blocking the peptidyl transferase reaction. Chloramphenicol resistance is encoded by the resistance gene cat, whose product, chloramphenicol acetyltransferase, inactivates the antibiotic via acetylation. Typically used at 30-50 µg/ml for selection of chloramphenicol-resistant Escherichia coli.

Predicting antibiotic efficacy within microbial communities remains highly challenging. Interspecies interactions can impact antibiotic activity through many mechanisms, including alterations to bacterial physiology. Here, we studied synthetic communities constructed from the core members of the fruit fly gut microbiota. Co-culturing
