Cover Story: Use of broad-spectrum antibiotics (e.g., doxycycline, minocycline) has been reported to alter the gut and skin microbiome leading to microbial dysbiosis. Dysbiosis has been associated with inflammatory disorders. Sarecycline was developed as the first narrow-spectrum tetracycline-class antibiotic to treat acne vulgaris. Narrow-spectrum antibiotics are hypothesized to cause minimal disruption of the endogenous gastrointestinal (GI) tract microbiota, thereby maintaining innate microbial diversity. To examine the breadth of this effect, a panel of microorganisms that reflect the diversity of the gut microbiome were evaluated with sarecycline compared to broad-spectrum minocycline using in vitro susceptibility testing and time-kill assays. View this paper
