Apis incidental bacteria

Many other bacteria have been found associated with honey bees, but in low numbers. We include Arsenophonus as it has possibly interesting biology.

Non-Apis bee bacteria common associates

Many other environmental bacteria are also found sporadically associated with Non-Apis bees. Very few of the nearly 20,000 species of bees have been studied, so this list will likely change drastically with future research.
