Therapeutics and Prevention
Research Article | Therapeutics and PreventionThe Multifaceted Antibacterial Mechanisms of the Pioneering Peptide Antibiotics Tyrocidine and Gramicidin SCyclic β-sheet decapeptides, such as tyrocidines and gramicidin S, were among the first antibiotics in clinical application. Although they have been used for such a long time, there is virtually no resistance to them, which has led to a renewed interest in this peptide class. Both tyrocidines and gramicidin S are thought to disrupt the bacterial membrane. However, this knowledge is mainly derived from in vitro studies, and...

In a previous mBio article, Wadsworth and colleagues (mBio 9:e01419-18, 2018, https://doi.org/10.1128/mBio.01419-18) described Neisseria gonorrhoeae isolates that express low levels of azithromycin (Azi) resistance. Whole-genome sequencing and bioinformatic analysis suggested that the isolates had acquired...
- Research Article | Therapeutics and PreventionStructural Basis of Pan-Ebolavirus Neutralization by a Human Antibody against a Conserved, yet Cryptic Epitope
There are five different members of the Ebolavirus genus. Provision of vaccines and treatments able to protect against any of the five ebolaviruses is an important goal of public health. Antibodies are a desired result of vaccines and can be delivered directly as therapeutics. Most antibodies, however, are effective against only one or two, not all, of these pathogens. Only one human antibody has been thus far described to...
