GUAM AND ITS PEOPLE

Biomagnification of cyanobacterial neurotoxins and neurodegenerative disease among the Chamorro people of Guam.

We here report biomagnification (the increasing accumulation of bioactive, often deleterious molecules through higher trophic levels of a food chain) of the neurotoxic nonprotein amino acid beta-methylamino-l-alanine (BMAA) in the Guam ecosystem. Free-living cyanobacteria produce 0.3 microg/g BMAA, but produce 2-37 microg/g as symbionts in the coralloid roots of cycad trees. BMAA is concentrate...

Early malaria cases on Guam were diagnosed as relapsing infections with the disease having been contracted in other areas. Small outbreaks...
