To identify the types of infections caused by Klebsiella spp. in a general surgery department and to analyze their antimicrobial susceptibility patterns. This retrospective observational study includes bacteriological cultures collected from surgical inpatients between October 2016 and December 2024. Only cases with confirmed Klebsiella spp. isolation were included. Specimen types, infection categories, and antibiotic susceptibility profiles were extracted and analyzed. A total of 138 Klebsiella-positive cultures were identified. Clinical characteristics were analyzed in 38 patients with complete records. The most common infection types included surgical site infections (SSIs), intra-abdominal infections, and biliary tract infections. Sensitivity was highest to carbapenems, while marked resistance was observed to ampicillin-sulbactam and third-generation cephalosporins. Some isolates exhibited ESBL or carbapenemase-producing phenotypes. Reported colistin non-susceptibility was elevated in our cohort; however, these results should be interpreted cautiously because the reference broth microdilution method was not systematically documented. The findings underscore the importance of local surveillance of Klebsiella spp. in surgical settings to info rm empirical treatment and control the spread of multidrug-resistant organisms.<\/jats:p>","DOI":"10.3390\/microorganisms14040773","type":"journal-article","created":{"date-parts":[[2026,3,30]],"date-time":"2026-03-30T13:41:53Z","timestamp":1774878113000},"page":"773","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Genus Klebsiella: Infections Encountered in a General Surgery Department and Antimicrobial Drugs Susceptibility Patterns"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0854-8164","authenticated-orcid":false,"given":"Sergiu-Ciprian","family":"Matei","sequence":"first","affiliation":[{"name":"Abdominal Surgery and Phlebology Research Center, \u201cVictor Babes\u201d University of Medicine and Pharmacy, 300041 Timisoara, Romania"},{"name":"1st Surgical Department, \u201cPius Brinzeu\u201d Emergency County Hospital, 300723 Timisoara, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Justin Horia","family":"L\u0103pu\u0219an","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, \u201cVictor Babes\u201d University of Medicine and Pharmacy, 300041 Timisoara, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-0871-6273","authenticated-orcid":false,"given":"Ana-Maria","family":"Ungureanu","sequence":"additional","affiliation":[{"name":"Department XV, Clinic of Radiology and Medical Imaging, \u201cVictor Babes\u201d University of Medicine and Pharmacy, Eftimie Murgu Square, No. 2, 300041 Timisoara, Romania"},{"name":"Department of Radiology and Medical Imaging, \u201cPius Brinzeu\u201d Emergency County Hospital, 300723 Timisoara, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-9704-3916","authenticated-orcid":false,"given":"Edida","family":"Maghet","sequence":"additional","affiliation":[{"name":"Faculty of Dental Medicine, \u201cVictor Babes\u201d University of Medicine and Pharmacy, 300041 Timisoara, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vlad","family":"Meche","sequence":"additional","affiliation":[{"name":"Doctoral School, \u201cVictor Babes\u201d University of Medicine and Pharmacy, 300041 Timisoara, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcel Berceanu","family":"Vaduva","sequence":"additional","affiliation":[{"name":"Department XVI\u2014Orthopedics-Traumatology\u2014I, Urology and Medical Imaging, \u201cVictor Babes\u201d University of Medicine and Pharmacy, 300041 Timisoara, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Claudia Livia","family":"Stanga","sequence":"additional","affiliation":[{"name":"Department XIV\u2014Microbiology, \u201cVictor Babes\u201d University of Medicine and Pharmacy, 300041 Timisoara, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mihaela","family":"Valcovici","sequence":"additional","affiliation":[{"name":"Department VI\u2014Cardiology, \u201cVictor Babes\u201d University of Medicine and Pharmacy, 300041 Timisoara, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0865-0054","authenticated-orcid":false,"given":"Abhinav","family":"Sharma","sequence":"additional","affiliation":[{"name":"Doctoral School, \u201cVictor Babes\u201d University of Medicine and Pharmacy, 300041 Timisoara, Romania"},{"name":"Department VI\u2014Cardiology, \u201cVictor Babes\u201d University of Medicine and Pharmacy, 300041 Timisoara, Romania"},{"name":"Research Centre of Timisoara, Institute of Cardiovascular Diseases, \u201cVictor Babes\u201d University of Medicine and Pharmacy, 300041 Timisoara, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2824-7182","authenticated-orcid":false,"given":"Nilima Rajpal","family":"Kundnani","sequence":"additional","affiliation":[{"name":"Department VI\u2014Cardiology, \u201cVictor Babes\u201d University of Medicine and Pharmacy, 300041 Timisoara, Romania"},{"name":"Research Centre of Timisoara, Institute of Cardiovascular Diseases, \u201cVictor Babes\u201d University of Medicine and Pharmacy, 300041 Timisoara, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,3,28]]},"reference":[{"key":"ref_1","first-page":"169","article-title":"A Comparative Study on Antibiotic Resistance of Klebsiella Strains from Surgical and Intensive Care Wards","volume":"42","author":"Cristea","year":"2016","journal-title":"Curr.
