Bee-killer wasps do not have the problem of antibiotic resistant pathogens
Bee-killer wasps use the same antibiotics for millions of years with no loss of efficacy - news

Beewolves or bee-killer wasps live in symbiosis with bacteria which produce around 45 antibiotics to protect the insects against infections. This symbiotic relationship begun 68 million years ago and surprisingly the antibiotics have remained stable ever since. For humans, the emerging resistance of multi-drug resistant pathogens is a problem, however no resistance to antibiotics has been developed in the case of the beewolves’ pathogens. The explanation is found in the composition of the antibiotics, which have a large spectrum of action, and in the behavior of the insets who, unlike humans, relocate frequently and live in small populations providing fewer opportunities for pathogens to adapt.
