Debromoaplysiatoxin in Lyngbya-dominated mats on manatees (Trichechus manatus latirostris) in the Florida King's Bay ecosystem.
Proliferation of the potentially toxic cyanobacterium, Lyngbya, in Florida lakes and rivers has raised concerns about ecosystem and human health. Debromoaplysiatoxin (DAT) was measured in concentrations up to 6.31 microg/g wet weight lyngbyatoxin A equivalents (WWLAE) in Lyngbya-dominated mats collected from natural substrates. DAT was also detected (up to 1.19 microg/g WWLAE) in Lyngbya-dominated mats collected from manatee dorsa. Ulcerative dermatitis found on manatees is associated with, but has not been proven to be caused by DAT.
