Clostridium difficile
C

D
Vibrio parahemolyticus
Explanation: 

Detailed explanation-1: -Clostridium difficile is a Gram-positive, spore-forming obligate anaerobe, belonging to the phylum Firmicutes. Both toxin-producing (toxigenic) and non-toxigenic strains exist naturally, and both can colonize their hosts (humans and non-human mammals), although only toxigenic strains are associated with disease.

Detailed explanation-2: -If your results were positive, it means your symptoms are likely being caused by C. diff bacteria. If you are diagnosed with a C. diff infection and are currently taking antibiotics, you will probably need to stop taking them.

Detailed explanation-3: -Clostridium difficile is an obligate anaerobic, spore-forming, Gram-positive rod first described in 1935 as Bacillus difficilis in the fecal flora of healthy infants.

Detailed explanation-4: -C. diff (also known as Clostridioides difficile or C. difficile) is a germ (bacterium) that causes diarrhea and colitis (an inflammation of the colon). It’s estimated to cause almost half a million infections in the United States each year.
