Toxins from Biological Sources

Toxins from biological sources, including microbial, algal, plant, and animal toxins, are a fascinating and hazardous category of toxicants. This topic distinguishes between toxins (produced by living organisms) and toxicants (synthetic or anthropogenic), covering key examples like bacterial exotoxins, mycotoxins (e.g., aflatoxin), algal toxins (e.g., saxitoxin, ciguatoxin), plant toxins (e.g., alkaloids), and animal venoms (e.g., snake, bee). For Zambian tertiary students in biomedical science, public health, and food safety, this knowledge is essential for understanding food poisoning, envenomation management, and natural product toxicology. The topic explores mechanisms of action, clinical syndromes, and public health implications, providing a solid foundation for examinations and future professional roles in diagnostics, toxicology, and environmental health across Zambia.
