Bacterial capsules play an important role in the virulence of bacteria for their host, and enable bacterial cells to evade host defense mechanisms and survive hostile environments. The structure and function of endospores and capsules work specifically to benefit the microbial cell; furthermore, various physiological changes occur in these structures as a result of environmental stress (Sahin, et. Al., 2012). The specific mechanism of these physiological changes, the types of environmental stresses that cause the changes, and how these correlate with endospore and capsular structure and function are essential to the understanding of this topic. Bacterial endospores are dormant, non-reproductive, and sometimes disease-causing cell structures that are typically formed in Gram-positive bacteria under a process called sporulation. Endospores exhibit high resistance to environmental stresses, and these structures are able to resist conditions that are unfavourable to most organisms, enabling bacteria to lie dormant for extended periods of time (hundreds to thousands of years). In addition, endospores are highly durable, as dormant spores return to an actively growing state a process called germination) when nutrients return to their environment. Sporulation is…
