Massachusetts Funeral Director Practice Exam

Tissue gas is caused by which type of bacteria?

1. Staphylococcus aureus

2. Escherichia coli

3. Clostridium perfringens

4. Salmonella spp.

The correct answer is: Clostridium perfringens

Tissue gas is primarily caused by Clostridium perfringens, which is an anaerobic bacterium that thrives in low-oxygen environments. This bacterium produces gas as a byproduct of its metabolic processes, particularly during the decomposition of tissue after death. It is known for its ability to invade tissues that have been compromised, often leading to significant gas formation, which can create distinctive and foul odors. In the context of funeral directing, understanding the role of Clostridium perfringens is crucial, especially in managing bodies that may have been subjected to conditions conducive to bacterial growth, such as delay in embalming. This knowledge can aid funeral directors in preventing and addressing odor and tissue-related complications during the preparation of the deceased. Other options listed are not associated with tissue gas specifically. Staphylococcus aureus and Escherichia coli are involved in various infections but do not typically produce the same type of tissue gas effects. Salmonella spp. are primarily linked to foodborne illnesses and gastrointestinal infections rather than post-mortem tissue gas formation.
