Final answer:
Pseudomonas aeruginosa is an aerobe, unable to grow without oxygen and known for causing infections in patients with cystic fibrosis and others in need of respiratory assistance.
Step-by-step explanation:
Pseudomonas aeruginosa is a common pathogen that affects the airways of patients with cystic fibrosis, and it does not grow in the absence of oxygen. Given this information, the bacterium is likely an aerobe. This microorganism is a strictly aerobic, nonfermenting, highly motile bacterium, and it is known for being an opportunistic pathogen that is resistant to many antibiotics. In the context of respiratory infections, particularly in patients with cystic fibrosis or those on mechanical ventilators, P.
aeruginosa can be a significant concern. Its ability to thrive in oxygen-rich environments and the production of yellow and blue pigments, which result in a green color in culture, are some distinctive features of this pathogen.Pseudomonas aeruginosa, a common pathogen that infects the airways of patients with cystic fibrosis, is most likely a aerobe. It requires oxygen to grow and does not grow in the absence of oxygen. Other examples of aerobes include bacteria that require oxygen for respiration and energy production.
