Example of bacteria requiring low concentration of oxygen is:
Correct answer: D. Campylobacter
- A. Spirochete
- B. Escherichia
- C. Pseudomonas
- D. Campylobacter
Explanation
Campylobacter is a genus of bacteria that includes several species, such as Campylobacter jejuni and Campylobacter coli. Campylobacter is microaerophilic, which means it requires low concentrations of oxygen (typically 5-10% oxygen) to grow optimally. It is not strictly anaerobic like some other bacteria but does not grow well in the presence of normal atmospheric levels of oxygen (around 20%). Campylobacter is commonly found in the intestines of birds and mammals and is a common cause of foodborne illnesses in humans.
