I must correct a mistake in my last posting. It was Israeli Acute Paralysis Virus (IAPV) of bees, not nosema ceranae, that people thought had been introduced by Australian package bees. The rest of my post is, I hope, accurate. IAPV, it turns out, also predated the introduction of Australian package bees.

Bees in the US have long suffered from the parasite nosema apis. The Nosema ceranae parasite is relatively new in the US, however. For some time it had been thought to have been introduced to US bees through imports of Australian bees, but research has shown that its presence antedates these imports and also the recent spate of colony collapse disorder. US researchers into CCD have considered it as a cause of CCD, but to the best of my knowledge US research has not implicated it as the cause, although it may be a contributing factor to the weakening of already stressed bee colonies. That it can be treated with fumagillin is also well known. It has been the object of considerable research in the US.
