Journal ArticleDOI
Contribution of hot spring cyanobacteria to the mysterious deaths of Lesser Flamingos at Lake Bogoria, Kenya
Lothar Krienitz,Andreas Ballot,Kiplagat Kotut,Claudia Wiegand,Stephanie Pütz,James S. Metcalf,Geoffrey A. Codd,Stephan Pflugmacher +7 more
TL;DR: Intoxication with cyanobacterial toxins could occur by uptake of detached cyanob bacterial cells from the mats, as the flamingos need to drink fresh or brackish water, and to wash their feathers daily, which they do in the vicinity of the hot springs, where salinity is lower than in the main body of water of the lake.
Journal ArticleDOI
Cyanobacteria and cyanobacterial toxins in three alkaline Rift Valley lakes of Kenya—Lakes Bogoria, Nakuru and Elmenteita
Andreas Ballot,Lothar Krienitz,Kiplagat Kotut,Claudia Wiegand,James S. Metcalf,Geoffrey A. Codd,Stephan Pflugmacher +6 more
TL;DR: Since A. fusiformis mass developments are characteristic of alkaline-saline lakes, health risks to wildlife, especial the Arthrospira-consuming Lesser Flamingo, may be expected.
Journal ArticleDOI
Paralytic Shellfish Poisoning Toxin-Producing Cyanobacterium Aphanizomenon gracile in Northeast Germany
TL;DR: This study is the first confirming the role of A. gracile as a PSP toxin producer in German water bodies and isolating and characterizing 92 Anabaena, Aphanizomenon, and Anabaenopsis strains from five lakes in northeast Germany.
Journal ArticleDOI
Cyanobacteria and cyanobacterial toxins in the alkaline crater lakes Sonachi and Simbi, Kenya
TL;DR: This is the first study showing A. fusiformis as producer of microcystins and anatoxin-a in two alkaline Kenyan crater lakes, and the first evidence of cyanobacterial toxins in L. Sonachi and L. Simbi.
Journal ArticleDOI
A review of the phylogeny, ecology and toxin production of bloom-forming Aphanizomenon spp. and related species within the Nostocales (cyanobacteria).
TL;DR: This review provides a thorough insight into the phylogeny, ecology, biogeography and toxicogenomics of the five best documented "Aphanizomenon" species with special relevance for water risk assessment.
