crithidia mellificae, IS this parasite causing hugh bee losses?
crithidia mellificae could this be the missing link in CCD?

Belgium study Showing correlation between nosema c. and crithidia mellificae and winter losses
http://www.plosone.org/article/info%...e-0020656-g006 USA STUDY,2011 The broad scope of our microarray platform enabled identification of an unexpected microbe, Crithidia mellificae, in our time-course samples (Figure 6). Given that Crithidia bombi is a bumble bee pathogen and trypanosomatids were previously described in honey bees , ,
The two species also differ significantly from another crithidia species, C. mellificae from the honey bee, which the researchers compared the bumblebee parasites with.
To the naked eye, however, the species can hardly be told apart – one reason why only genetic tests revealed the correct species they belonged to. That said, C. expoeki is slightly larger than C. bombi, as measurements conducted on the protozoa demonstrated. ,
The two pathogens are found all over the world. They have also reached new areas because the large earth bumblebee – either naturally or introduced by man – has also spread. Breeders from Belgium and the Netherlands in particular sent their bumblebees all over the world, where the industrious insects were used as pollinators in agricultural cultures. They also took the single-celled parasites with them as stowaways. In North America, for example, a dramatic decline has been observed in bumblebees for some time now. This could be due to the crithidia introduced.
