Cryptobiosis research?

A search of PubMed (National Library of Medicine
     http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=PubMed
gave  only 18 hits.  However it turns out that there is a protist
parasite of fish called Cryptobia that causes a disease named
cryptobiosis so many of the citations are inappropriate.

Try
   Gutierrez JC, Martin-Gonzalez A, Matsusaka T.
   Towards a generalized model of encystment (cryptobiosis)
   in ciliates: a review and a hypothesis.
   Biosystems. 1990;24(1):17-24.

My favorite search service, www.google.com,
gave surprisingly little of use except a lot of tardigrade sites.

There must be a better search descriptor.  Or else it is simply
not that active an area of research.
