Anaerobic bacteremia represents 0.5-12% of all bacteremias and its mortality is high, ranging from 25-44%. The aim was to know our data to compare them with existing data and demonstrate the importance of actively searching for these microorganisms in blood culture samples. Material and methods. A retrospective descriptive study in which the medical records of patients with significant episodes of anaerobic bacteremia were reviewed over a period of 8 years (2014-2022). Results. A total of 59,898 blood cultures were processed, of which 10,451 were positive (17%). An anaerobic microorganism was identified in 209 patients. Anaerobic bacteremia accounted for 2.11% of the total number of positive blood cultures. The mean age was 63.55 years (17-96), 66% of whom were men. The origin was community in 63.64%, of nosocomial origin in 15.31% and associated with health care in 17.70%. The focus of infection was the abdominal (39.23%), followed by the respiratory (13.88%) and skin and soft tissues (13.39%). The most frequent comorbidities were: arterial hypertension (49.76%), dyslipidemia (29.67%), neoplasia (26.32%) and diabetes (26.32%). The main species isolated were the group Bacteroides spp. (44.50%) (n=93) highlighting Bacteroides group fragilis (n=65), followed by Clostridium spp. (20%) (n=42) highlighting Clostridium perfringens (n=30). The clinical evolution was good in 67.46%. The mean length of stay was 27.8 days and was associated with 20% mortality. Conclusions. Bacteremias due to anaerobes represented 2.11% of the total number of true bacteremias, so we consider the active search for these microorganisms to be appropriate.<\/jats:p>","DOI":"10.37201\/req\/063.2024","type":"journal-article","created":{"date-parts":[[2024,11,18]],"date-time":"2024-11-18T16:08:28Z","timestamp":1731946108000},"page":"21-27","source":"Crossref","is-referenced-by-count":0,"title":["Bacteremia due to strict anaerobes"],"prefix":"10.37201","volume":"38","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-9505-2517","authenticated-orcid":false,"given":"Carmen","family":"Pi\u00f1a Delgado","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1829-7335","authenticated-orcid":false,"given":"Margarita","family":"Bola\u00f1os Rivero","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7244-8301","authenticated-orcid":false,"given":"Mar\u00eda Nieves","family":"Carmona Tello","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-2223-8954","authenticated-orcid":false,"given":"Catalina Jes\u00fas","family":"Ram\u00edrez Estupi\u00f1\u00e1n","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1908-8113","authenticated-orcid":false,"given":"Pilar Michele","family":"Hern\u00e1ndez Cabrera","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Isabel","family":"de Miguel Mart\u00ednez","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"23328","published-online":{"date-parts":[[2024,11,18]]},"container-title":["Revista Espa\u00f1ola de Quimioterapia"],"original-title":["Bacteriemias por anaerobios estrictos"],"deposited":{"date-parts":[[2025,1,10]],"date-time":"2025-01-10T15:40:00Z","timestamp":1736523600000},"score":1,"resource":{"primary":{"URL":"https:\/\/seq.es\/abstract\/rev-esp-quimioter-2024-november-18-2\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,11,18]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2025,1,10]]},"published-print":{"date-parts":[[2025,1,10]]}},"URL":"https:\/\/doi.org\/10.37201\/req\/063.2024","relation":{},"ISSN":["0214-3429","1988-9518"],"issn-type":[{"type":"print","value":"0214-3429"},{"type":"electronic","value":"1988-9518"}],"subject":[],"published":{"date-parts":[[2024,11,18]]}}}
