Final answer:
The treatment with a capsule of probiotic bacteria instead of fecal microbiota transplantation (FMT) might not be as comprehensive due to the limited strains of bacteria in capsules.
Step-by-step explanation:
The treatment that is possible for people who have too much C. difficile in their digestive system includes taking antibiotics like metronidazole or having a fecal transplant from a healthy donor. Additionally, taking probiotic supplements can also help restore the microbial intestinal community. While antibiotics directly target the pathogenic bacteria, probiotic bacteria and fecal microbiota transplantation (FMT) work by restoring the balance of the gut microbiota. FMT is more comprehensive as it includes a wide array of microbes from a healthy donor's feces, potentially offering a greater chance to restore balance compared to a capsule of probiotic bacteria that usually contains a limited number of strains.
Therefore, the answer could change if a capsule of probiotic bacteria is used instead of FMT. This is because the diversity and the number of microbial species introduced via a capsule can be significantly lower than those introduced through FMT. However, both methods aim to achieve the same outcome of restoring a healthy microbial balance in the intestine.
