The prognosis for pyomyositis caused by Gram-negative bacteria is more unfavorable than that of infections caused by Staphylococcus aureus. Among Gram-negative bacteria, members of the Enterobacteriaceae family, including Escherichia coli, Klebsiella species, and Salmonella species, have the capacity to produce gas. Gas-forming myositis is a rare phenomenon that primarily affects immunocompromised patients and is associated with a poor prognosis. To the best of our knowledge, no previous reports of gas-forming pyomyositis in an immunocompetent patient exist. We herein present the first documented case of Salmonella-induced gas-forming pyomyositis of the iliacus muscle in a healthy young man with no underlying diseases or comorbidities. Additionally, we reviewed cases of gas-forming pyomyositis in the literature and cases of pyomyositis caused by Gram-negative bacteria in immunocompetent patients.<\/jats:p>","DOI":"10.1177\/03000605241311782","type":"journal-article","created":{"date-parts":[[2025,1,28]],"date-time":"2025-01-28T22:04:26Z","timestamp":1738101866000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["<i>Salmonella<\/i>\n
