ABSTRACT

gastrointestinal and cardiac symptoms, and in some cases, chronic neurologic symptoms. In the Philippines, diagnosis

experienced temperature reversal sensation. Cigua-Check Kit screening done by the Bureau of Fisheries and mass spectrometry, which showed masses corresponding to those of CTX-1 and CTX-3B/3C. Since an increased occurrence of CFP in the Philippines is anticipated as a consequence of global climate change, validation of CFP by other methods like mass spectrometry will be useful for more effective diagnosis and management of CFP.
