However, there have been very few cases of hepatic space-occupying lesions associated with this infection. Currently, there are various methods for detecting this pathogen, including metagenomic sequencing, which enables quicker and more accurate identification. In this study, metagenomic sequencing is employed to accurately identify non-O1\/O139 <jats:italic>Vibrio cholerae<\/jats:italic> infections by analyzing the genetic material present in clinical samples.<\/jats:p><\/jats:sec><jats:sec><jats:title>Presentation of case<\/jats:title><jats:p>A 75-year-old man presented with diarrhea and fever after consuming crabs. The initial treatment improved the diarrhea, but a liver abscess developed later. Magnetic resonance imaging (MRI) of the liver revealed a hepatic space-occupying lesion. Upon further investigation, a Gram-negative, rod-shaped bacterium was cultured from the patient\u2019s liver puncture fluid, and <jats:italic>Vibrio cholerae<\/jats:italic> was detected in the same fluid using metagenomic next-generation sequencing (mNGS). The pathogen was confirmed to be non-O1\/non-O139 <jats:italic>Vibrio cholerae<\/jats:italic> (<jats:italic>NOVC<\/jats:italic>) using polymerase chain reaction (PCR). Following treatment with piperacillin\/tazobactam sodium and moxifloxacin, the patient\u2019s body temperature returned to normal, the liver abscess improved significantly, and he was subsequently discharged from the hospital.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>This case study describes an elderly male patient with a hepatic space-occupying lesion. Multiple cultures of specimens failed to identify the underlying cause; however, advanced techniques such as mNGS and PCR confirmed an <jats:italic>NOVC<\/jats:italic> infection. This indicates that mNGS can serve as a valuable tool in diagnosing cases of unexplained liver infections.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The use of mNGS is significant for detecting and clinically diagnosing infectious pathogens in patients with unexplained space-occupying lesions.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fmed.2024.1483027","type":"journal-article","created":{"date-parts":[[2024,11,19]],"date-time":"2024-11-19T04:24:13Z","timestamp":1731990253000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Case report: Detection of non-O1\/non-O139 Vibrio cholerae in a patient with hepatic space-occupying lesions using metagenomic next-generation sequencing"],"prefix":"10.3389","volume":"11","author":[{"given":"Wei","family":"Zhang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Li","family":"Xiao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xingxing","family":"Shan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bing","family":"Dai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chunyan","family":"Tang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianchun","family":"Xian","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yan","family":"Yu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2024,11,19]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"1539","DOI":"10.1016\/S0140-6736(17)30559-7","volume":"390","author":"Clemens","year":"2017","journal-title":"Cholera Lancet"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"104726","DOI":"10.1016\/j.meegid.2021.104726","article-title":"Evolution, distribution and genetics of atypical Vibrio cholerae - a review","volume":"89","author":"Bhandari","year":"2021","journal-title":"Infect Genet Evol"},{"key":"ref3","doi-asserted-by":"publisher","first-page":"774","DOI":"10.1086\/514947","article-title":"Infections due to non-O1 Vibrio cholerae in southern Taiwan: predominance in cirrhotic patients","volume":"27","author":"Ko","year":"1998","journal-title":"Clin Infect Dis"},{"key":"ref4","doi-asserted-by":"publisher","first-page":"1009","DOI":"10.2147\/IDR.S245806","article-title":"Non-O1, non-O139 Vibrio cholerae (NOVC) bacteremia: case report and literature review, 2015-2019","volume":"13","author":"Zhang","year":"2020","journal-title":"Infect Drug Resist"},{"key":"ref5","doi-asserted-by":"publisher","first-page":"601","DOI":"10.1016\/j.jiph.2018.01.001","article-title":"Non-O1, non-O139 Vibrio cholerae septicemia at a tertiary care center in Beirut, Lebanon;
