Advected cyanobacteria, algal blooms and cyanotoxins have been increasingly detected in freshwater ecosystems. This review gives an insight into the present state of knowledge on taxonomy, dynamics, toxic effects, human ecological health implications East African Community lakes. The major toxigenic microalgae lakes include Microcystis, Arthrospira, Dolichospermum, Planktolyngbya Anabaenopsis s...

Cyanobacteria are a diverse well adapted group of organisms that presents amazing morphological diversity. Cyanobacteria can be unicellular or colonial (filamentous, spherical or amorphous) (Fig. 1). Since cyanobacteria have cells larger than normal bacterial cells and behavior more similar to algae, they were classified under the microalgae for a long time and acquire the name of blue-green al...
