Serratia is a type of bacteria commonly found in the environment and sometimes in the human intestinal tract. While usually harmless in healthy individuals, its presence in stool may be concerning for those with certain health conditions. Detection in stool tests can signal possible gut flora imbalances or infections.
Testing for Serratia in stool is important for individuals with gastrointestinal symptoms, immune-compromised patients, or those with a history of intestinal issues. It’s also helpful for people experiencing unexplained digestive discomfort or after a course of antibiotics.
Serratia species occur in a variety of infections. Elevated levels also often occur in people with diarrhea.
Serratia in stool can result from environmental exposure or ingestion. It can also proliferate due to a disrupted gut microbiome, often caused by antibiotic use or gastrointestinal disorders. Poor hygiene and contaminated food or water are other potential sources.
