Pseudomonas in stool refers to the presence of bacteria from the Pseudomonas genus, most commonly Pseudomonas aeruginosa, in the gastrointestinal tract. While it is not usually a common resident of the gut, it can cause infection or overgrowth, especially in people with weakened immune systems. Its detection may indicate an imbalance in the gut microbiota or an underlying condition, particularly if gastrointestinal symptoms are present.
Elevated levels of Pseudomonas species may occur in inflammation of the intestine. Elevated levels can lead to diarrhea and loose stool.
Testing for Pseudomonas in stool is beneficial for those with persistent gastrointestinal issues, especially if immunocompromised or after a recent hospital stay. This includes patients with chronic gut diseases, those who have undergone recent antibiotic therapy, and individuals with a history of hospital-acquired infections.
