Abstract

Livestock deaths, and clinical reports of human injury, follow the consumption of toxic blue-green algae. The experiments described show that isolated intestinal enterocytes from chicks are both deformed and killed by exposure to Microcystis toxins, in a dose-dependent and time-dependent manner. The enterocytes were protected from toxicity by deoxycholate, bromosulphothalein and rifampicin. It was concluded that the gastroenteritis clinically associated with accidental Microcystis ingestion is likely to reflect enterocyte injury by Microcystis toxins, and that the therapeutic use of bile acids or transport inhibitors may be of value in treatment.
