Final answer:
Clostridium difficile is a gram-positive bacterium that can cause severe health issues, particularly in health-care settings. It produces two toxins that result in actin condensation, cell rounding, and ultimately cell death. Infections can lead to pseudomembranous colitis and a range of symptoms including diarrhea, dehydration, and abdominal pain.
Step-by-step explanation:
Gram-positive Clostridium difficile is a bacterium that can seriously harm people, especially in medical environments. The two toxins that this bacterium produces, Clostridium difficile toxin A (TcdA) and Clostridium difficile toxin B (TcdB), cause actin condensation, rounding of the cell morphology, and eventually death of the cell. Pseudomembranous colitis is a condition that results from infections that causes inflammation in the colon and the formation of a pseudomembrane that contains leukocytes and dead epithelial cells. An infection with Clostridium difficile can cause watery diarrhea, fever, dehydration, appetite loss, and stomach pain. Severe circumstances may result in colon perforation, which can cause septicemia, shock, and even death.
