15. Some Gram-positive bacteria belonging to the genera Bacillus (e.g. B. anthracis) and Clostridium (e.g. C. difficile) are able to form endospores. What is an endospore, and what is its benefit?

Expert Solution

Endospores are a complex, multi-layered, dormant, and non-reproductive structure produced by some bacteria in conditions of stress. The formation of endospores is usually initiated due to a lack of nutrients in the environment. It is mostly found in Gram-positive organisms. An endospore consists of DNA of a bacterium, its ribosomes, and also large amounts of a chemical compound known as dipicolinic acid. This chemical enables an endospore to maintain its dormancy. Also, an important point to note is that these endospores are resistant to all physical and chemical treatments like exposure to UV, high temperature, chemical disinfectants, etc.

Benefits

In times of extreme stress, the formation of endospores preserves the cell's genetic material.

It helps bacteria to cope up with extreme stress conditions.

Due to their tough shell made of calcium dipicolinate, they become resistant to antibiotics and other agents.

Clostridium difficile (C. diff) is a gram-positive bacillus that produces produces spores and toxins that can cause extreme diarrhea, abdominal pain, fever, loss of appetite and nausea. The main transmission of C. diff is from person to person through the fecal-oral route and contaminated surfaces, such as doorknobs, bathtubs and medical equipment. If a surface becomes contaminated with C. diff it can be transferred to patients mainly via the hands of healthcare personnel who have touched a contaminated surface or...

The Gram-negative bacillus bacteria Klebsiella pneumoniae is a major cause of nosocomial infections, primarily among immunocompromised patients. The emergence of new strains has left few treatment options, making infection containment critical. Recently, the U.S. National Institutes of Health Clinical Center experienced an outbreak of K. pneumoniae that affected 18 patients, 11 of whom died. In addition to standard PPE and aseptic technique - think creatively and propose 2 stronger disinfection protocols that a hospital could use to prevent future infections:
