In general, N. cyriacigeorgica causes infections in immunocompromised individuals and has been reported in clinical samples worldwide. However, the isolation and speciation of N. cyriacigeorgica in the routine diagnostic microbiology laboratory are complicated and time consuming. Recent mass spectrometry techniques such as matrix-assisted laser desorption\/ionization time-of-flight-mass spectrometry (MALDI-TOF-MS) have been successfully integrated into many routine diagnostic microbiology laboratories, allowing for the rapid, accurate and simple identification and speciation of many different microorganisms, including difficult-to-identify bacterial species. Here, we present a case report of a 65-year-old female patient from the neurology ward of Prince Sultan Military Medical City in Riyadh, Saudi Arabia, who was infected with N. cyriacigeorgica. The bacterium was successfully identified by MALDI-TOF-MS, with species identification subsequently confirmed by sequence analysis of the 16S ribosomal RNA.<\/jats:p>","DOI":"10.1093\/omcr\/omaa088","type":"journal-article","created":{"date-parts":[[2020,10,23]],"date-time":"2020-10-23T13:01:08Z","timestamp":1603458068000},"source":"Crossref","is-referenced-by-count":5,"title":["Rapid identification of Nocardia cyriacigeorgica from a brain abscess patient using MALDI-TOF-MS"],"prefix":"10.1093","volume":"2020","author":[{"given":"Mohammed","family":"AlMogbel","sequence":"first","affiliation":[{"name":"Molecular Diagnostic and Personalized Therapeutics unit, College of Applied Medical Sciences, University of Ha\u2019il, Ha\u2019il, Kingdom of Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammed","family":"AlBolbol","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Prince Sultan Military Medical City, Riyadh, Kingdom of Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Noura","family":"Elkhizzi","sequence":"additional","affiliation":[{"name":"Medical Microbiology Division, Central Military Laboratory and Blood Bank, Prince Sultan Military Medical City, Riyadh, Kingdom of Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hisham","family":"AlAjlan","sequence":"additional","affiliation":[{"name":"Medical Microbiology Division, Central Military Laboratory and Blood Bank, Prince Sultan Military Medical City, Riyadh, Kingdom of Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John Philip","family":"Hays","sequence":"additional","affiliation":[{"name":"Department of Medical Microbiology and Infectious Diseases, Erasmus University Medical Centre Rotterdam (Erasmus MC), Rotterdam, the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2434-1411","authenticated-orcid":false,"given":"Mushtaq Ahmad","family":"Khan","sequence":"additional","affiliation":[{"name":"Department of Medical Microbiology and Immunology, College of Medicine and Health Sciences, United Arab Emirates University, Al Ain, United Arab Emirates"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2020,10,23]]},"reference":[{"key":"2020102309003586700_ref1","first-page":"5184386","article-title":"Pulmonary infections caused by emerging pathogenic species of Nocardia","volume":"2019","author":"Manoharan","year":"2019","journal-title":"Case Rep Infect Dis"},{"key":"2020102309003586700_ref2","doi-asserted-by":"publisher","first-page":"e00422","DOI":"10.1016\/j.idcr.2018.e00422","article-title":"Nocardia paucivorans brain abscess.
