Jim asks >Peter, where's the article from which you quote?

It was from a Penn State news release but the work is reported as

"Impact of an ectoparasite on the immunity and pathology of an invertebrate:
Evidence for host immunosuppression and viral amplification" by Xiaolong
Yang and Diana L. Cox-Foster*

Proceedings of the National Academy of Sciences May 24, 2005  vol. 102  no. 21
