Cryptocaryoniasis (also known as marine white spot disease) is mediated by Cryptocaryon irritans. This
obligate ectoparasitic protozoan infects virtually all marine teleosts, which includes Lates calcarifer,
a highly valuable aquaculture species. Little is known about L. calcarifereC. irritans interactions. This
study was undertaken to gain an informative snapshot of the L. calcarifer transcriptomic response over
the course of C. irritans infection. An in-house fabricated cDNA microarray slides containing 3872 probes
from L. calcarifer liver and spleen cDNA libraries were used as a tool to investigate the response of
L. calcarifer to C. irritans infection.
