Certification in Infection Prevention and Control (CIC) Practice Exam

Gas gangrene is primarily associated with spores of Clostridium species, particularly Clostridium perfringens, which are naturally found in the soil. These bacteria can survive in a dormant spore form in the environment and can enter the body through traumatic injuries, such as wounds or surgical incisions. Once inside the body, these spores can become active in anaerobic conditions, leading to the rapid onset of gas gangrene.

Soil serves as a key reservoir for these bacteria due to its ability to harbor a variety of microorganisms, including those capable of causing infection. The presence of organic material in the soil also supports the growth of Clostridium species. Unlike other options, such as other people, food, or animals, soil remains a more direct and effective immediate source of contamination that can result in the disease, particularly in scenarios involving injuries where the bacteria can be introduced into the body.

Understanding the natural reservoirs of pathogens is crucial for infection prevention and control, as this knowledge helps healthcare professionals implement effective strategies to mitigate risks associated with these infections.
