Final answer:
Capnophiles are organisms that require incubation in increased CO2. Neisseria species, Haemophilus species, Brucella species, Campylobacter species, and Legionella species are examples of organisms requiring increased CO2 for growth.
Step-by-step explanation:
Capnophiles are organisms that require incubation in increased CO2. Organisms listed in the question that fall under this category include: Neisseria species, Haemophilus species, Brucella species, Campylobacter species, and Legionella species.
These organisms thrive in environments with higher levels of CO2 and lower levels of oxygen compared to the normal atmospheric conditions.
They are often grown in specialized conditions such as a candle jar, where a candle consumes oxygen and releases CO2. This creates an atmosphere suitable for the growth of capnophiles.
Overall, capnophiles highlight the specific environmental requirements of certain organisms and their ability to adapt to different conditions for growth and survival.
