A potential antimicrobial drug is tested and found to strip away the capsules made by certain pathogenic bacteria. How would thi
LekaFEV [45]

Answer & explanation:

The capsule is one of the main virulence factors (ability of a microorganism to cause disease) of bacteria, protecting them from phagocytosis (when a specialized cell called a "macrophage" encompasses invading particles in order to prevent damage to the organism) and recognition by the immune system. This allows them to survive, multiplicate and disseminate to various organs.

In addition, the capsule provides adhesion to surfaces (as well as flagella, fimbriae and adhesins), facilitating colonization.

By stripping the capsule of a bacterium, the antimicrobial agent would decrease its virulence not only by hindering its adhesion to body surfaces and structures, but also by limiting its defense against phagocytosis by eukaryotic cells (such as macrophages).

Dmitrij [34]

The difference is due to the dose and the purpose of the radiation.

<h3>What is radiology?</h3>

Radiology is the application of radiation in medicine to diagnose or to treat diseases.

Diagnosis of diseases is aimed at identifying the cause of a disease.

Treatment of diseases is aimed at curative purposes.

Therefore, one patient will have a radiologic procedure to diagnose a condition because the cause of the disease is yet to be ascertained, while another has radiation treatment to destroy a tumor because radiation can destroy tumors at a particular dose.

In conclusion, radiation can be use to diagnose or treat diseases based on the dose.
