There are two problems with antibiotics:
1. lack of new antibiotics — since 1987, no new antibiotic has been approved for clinical practice
2. resistance — hence, “superbug” — e.g. antibiotic-resistant strains of tuberculosis
Together, these two problems have raised the spectre of a future without antibiotics.
Now, a new method of identifying new antibiotics has been developed. Twenty five antibiotics have so far been discovered, using this method, with the promise of more to come.
Teixobactin, most promising of the new antibiotics, works in a way not seen before: by attacking fats which are essential to building the cell wall of bacteria.
Because of this unique method of operation, it is hoped that resistance won’t be a problem. While there are reasons to hope that this may be true, similar claims have been made for many, if not all new antibiotics & antiseptics.
