However, to date, no reviews have specifically investigated P. shigelloides bacteremia, which is rare and potentially fatal. This scoping review aimed to examine the existing literature to identify the epidemiology, clinical characteristics, antimicrobial susceptibility, and outcomes of P. shigelloides bacteremia. A PRISMA-ScR-guided search of PubMed, Scopus, Web of Science, and Embase identified 22 published cases, all reported as single-patient case reports. Cases were globally distributed, with the majority reported from the Americas and Europe. The median patient age was 46 years. The case fatality rate was 27.3% (n = 6\/22). Most patients had identifiable host risk factors, particularly hematological disorders, neonatal status, or immunocompromised status, and environmental exposure such as raw seafood consumption or contact with freshwater. Clinical presentations were heterogeneous, commonly including fever and sepsis or septic shock. Microbiologically, P. shigelloides demonstrated consistent intrinsic resistance to ampicillin while retaining susceptibility to multiple antimicrobial classes. Poor outcomes were more closely associated with host factors and delayed presentation than with antimicrobial resistance. Early diagnosis, targeted therapy, and antimicrobial stewardship are essential for optimizing outcomes in this rare but severe infection.<\/jats:p>","DOI":"10.3390\/pathogens15010123","type":"journal-article","created":{"date-parts":[[2026,1,23]],"date-time":"2026-01-23T09:16:59Z","timestamp":1769159819000},"page":"123","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Plesiomonas\u00a0shigelloides Bacteremia: A Scoping Review of Epidemiology, Clinical Characteristics, Outcomes, and Implications of Antimicrobial Stewardship"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-2487-3396","authenticated-orcid":false,"given":"Nur Izzatul Auni","family":"Romli","sequence":"first","affiliation":[{"name":"Department of Medical Microbiology, Faculty of Medicine, Universiti Malaya, Lembah Pantai, Kuala Lumpur 50603, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Salina","family":"Mohamed Sukur","sequence":"additional","affiliation":[{"name":"Kementerian Kesihatan Malaysia, National Institutes of Health (NIH), No. 1, Jalan Setia Murni U13\/52, Seksyen U13, Bandar Setia Alam, Shah Alam 40170, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kumutha Malar","family":"Vellasamy","sequence":"additional","affiliation":[{"name":"Department of Medical Microbiology, Faculty of Medicine, Universiti Malaya, Lembah Pantai, Kuala Lumpur 50603, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8716-4416","authenticated-orcid":false,"given":"Kartini","family":"Abdul Jabar","sequence":"additional","affiliation":[{"name":"Department of Medical Microbiology, Faculty of Medicine, Universiti Malaya, Lembah Pantai, Kuala Lumpur 50603, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,1,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"349","DOI":"10.1128\/CMR.00103-15","article-title":"Plesiomonas shigelloides Revisited","volume":"29","author":"Abbott","year":"2016","journal-title":"Clin.
