APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Endospores are resistant to the chemical agents, e.g., triphenylmethane dyes, and can even protect the bacterial cells against ultraviolet radiation, extreme pH gradients, drought, and nutrition depletion.

Detailed explanation-2: -The core wall lies beneath the cortex and surrounds the protoplast or core of the endospore. The core contains the spore chromosomal DNA which is encased in chromatin-like proteins known as SASPs (small acid-soluble spore proteins), that protect the spore DNA from UV radiation and heat.

Detailed explanation-3: -It allows the bacterium to produce a dormant and highly resistant cell to preserve the cell’s genetic material in times of extreme stress. Endospores can survive environmental assaults that would normally kill the bacterium.

Detailed explanation-4: -Endospores are a resistant, dormant, survival form of bacteria. They are resistant to high temperatures, most disinfectants, low level radiation and drying. Endospores can survive thousands of years until environmental stimuli trigger germination.
