Topic hierarchy

14.4A: Toxins
Toxins are poisonous substances produced within living cells or organisms and can include various classes of small molecules or proteins that cause disease on contact. The severity and type of diseases caused by toxins can range from minor effects to deadly effects. The organisms which are capable of producing toxins include bacteria, fungi, algae, and plants. Some of the major types of toxins include, but are not limited to, environmental, marine, and microbial toxins.
14.4B: Direct Damage
14.4C: Type III and Type IV Secretion
14.4D: Plasmids and Lysogeny
Both plasmids and lysogeny are used by bacteria and viruses to ensure transfer of genes and nucleic acids for viral reproduction.
14.4E: Siderophores
Siderophores produce specific proteins and some siderophores form soluble iron complexes to aid in iron acquisition for survival.
