Does it also inhibit cell wall synthesis of non-bacteria cells? If yes, it's toxic to us. If no, bacteria cell walls could evolve to be more like non-bacteria cell walls in order to avoid this. Two links from the Wikipedia article on Teixobactin about this: http://www.the-scientist.com/?articles.view/articleNo/41850/... http://www.bbc.com/news/health-30657486 (Actually, Teixobactin only works on gram-positive bacteria, not on gram-negative ones which have an extra membrane.)

Only bacteria, plants, fungi, etc. have cell walls. Animals don't have them.

All cells do have a cell membrane, but that's a totally different structure.

Thanks for the correction.

The real mechanism of resistance is in how it inhibits cell wall synthesis. Plus there are general mechanisms such as drug efflux and prevention of drug entry into the cell.

See, it must be specific enough to not kill our cells, otherwise it is worthless.
