What is one of the main characteristics of C. perfringens infections?

Rapid healing of wounds
Presence of gas in tissues
Increase in blood cell counts
Reduction of blood supply

The correct answer is: Presence of gas in tissues

The main characteristic of C. perfringens infections is the presence of gas in tissues. C. perfringens is an anaerobic bacterium that can produce gas as a result of its metabolic processes. This gas formation is particularly associated with gas gangrene, a serious condition where the bacteria invade and proliferate in injured or necrotic tissue. The production of gas can lead to swelling and severe pain in the affected area. The gas can accumulate in the tissues and cause characteristic crepitus, which is the sensation felt when the skin is palpated over gas-filled tissues. The other choices do not accurately capture the primary feature of C. perfringens infections. While there may be some increase in blood cell counts as part of the body's immune response to infection, it is not a defining characteristic. Rapid healing of wounds is generally not associated with C. perfringens infections, as these infections can severely delay healing due to tissue death and necrosis. Reduction of blood supply can occur as a result of tissue damage, but it is not a direct characteristic of the infection itself. Therefore, the presence of gas in tissues is key to identifying and diagnosing C. perfringens infections.
