I have been searching myself and so far nosema ceranae dates to around 2000 (
maybe farther but not confirmed by the USDA-ARS to me).

Reply:
Has already been confirmed going back further, and posted here too I believe; so far the mid-1980s, and is why I opened files I have, to see how further back findings in USA were. For if both types Nosema found in looking at old samples in 1980s,... then why not look further back and believe it or not it does go back even further beyond 1959 for Nosema in USA, just like with mites fwiw? Also, the time frame for initially finding in EU matches transitions in industry for what they doing in both USA and EU, so we should have known what to expect before hand.........at least in my thoughts!!
