What is a distinguishing feature of actinomyces israelii?

It is a virus
It is an anaerobic bacterium
It is a saprophytic organism
It is a protozoan

The correct answer is: It is an anaerobic bacterium

Actinomyces israelii is primarily known as an anaerobic bacterium, meaning it thrives in environments that lack oxygen. This characteristic is significant because it influences how the bacterium behaves in the human body and its modes of transmission. A. indicates that it is a virus, which is incorrect because Actinomyces israelii is a type of bacteria, not a virus. C. refers to the organism being saprophytic; while Actinomyces can be involved in the decomposition of organic material, its role as a pathogen in humans is more critical than this characteristic alone suggests. D. mistakenly classifies it as a protozoan, which is not accurate as Actinomyces israelii is not a unicellular organism but rather a prokaryotic bacterium. Therefore, its identification as an anaerobic bacterium is essential in medical contexts, particularly concerning infections and the necessary environments for its growth and potential treatment options.
