I'm no scientist, but I play with them at work. We host the country's only NIH bacterial pathogen bioinformatics resource center, and have close ties with the other BRCs, including the parasite folks. I'll make a few inquiries when I get back from vacation.

On first glance, this article looks like an industry plant. MB Lee, according to PubMed (THE source for bio-med research), has exactly this one article to his (?) credit, which screams grad student to me, and not a very good one either. The grad students in my building all have multiple pubs. It is hard to tell, of course, because of the multitude of M. Lees that could also be him/her.

Vetech looks like an Agri-biz that makes poultry vaccines. Why would a top-flight parasitologist be making chicken shots?

Something smells, here.

The line that really jumped out at me is the one, near the end, where they admit that they use conditions that no one is likely to encounter. Basically, they are using a sample full of a strong lab strain of cysts, at a level that simply does not occur in nature.

Bull**it. In more ways than one.
