Study Notes
Microbial Resistance
- Spores demonstrate the highest resistance to environmental stresses and chemicals.
- Vegetative cells show moderate resistance.
Microbial Forms
- Viruses are the least resistant microbial form, as they are highly sensitive to environmental factors and chemicals.
- Lethal mutations are characterized by permanent loss of reproductive capability.
Microbial Death
- Microbial death is hard to detect due to the inability to distinguish between dormant and dead cells, as well as the presence of viable but non-culturable cells.
Test your knowledge of microbial control methods, including physical and chemical agents for microbial control, and the relative resistance of microbes. Explore the effectiveness of different control methods in eliminating microbes and protecting public health.
