Helicobacter spp. — Food- or Waterborne Pathogens?

Although H. pylori is a known cause of ulcers and gastric cancer, it resides in the gastrointestinal tract of about half the world's population who are usually asymptomatic. Some other Helicobacter species infect mammals, birds and reptiles. Transmission of H. pylori is not well understood because these bacteria enter a viable but nonculturable state when exposed to stressful conditions outside the body.

Toxins from Cyanobacteria

Human exposure to cyanobacterial toxins primarily occurs through ingestion of contaminated water or shellfish, with some additional exposure through dietary supplements, other foods, and aerosols from lakes with cyanobacterial blooms. This review addresses recent information on microcystins, β-methylamino-L-alanine, paralytic shellfish toxins, and anatoxin-a.
