In this retrospective study, we examined the utility of Gram stains and compared 3 culture methods.<\/jats:p>\n                  <jats:p>We examined a laboratory cohort (samples sent to the laboratory for any reason; n = 251) and a clinical cohort (samples sent from patients felt clinically to have peritonitis; n = 264). Culture positivity rates were higher in the clinical cohort (39.4%) than the laboratory cohort (21.5%), with no difference in the distribution of organisms between the cohorts; cell counts were significantly higher in culture-positive samples in both cohorts.<\/jats:p>\n                  <jats:p>Rates of positivity in the laboratory and clinical cohorts, respectively, were as follows: Gram stains 1.9% and 7.7%; direct plate culture 13% and 30.8% and \u201cbedside\u201d inoculated blood culture bottles 82.1% and 92.8%. Enrichment culture was never negative when another method was positive.<\/jats:p>\n                  <jats:p>Our data indicate that enrichment culture can be used as a single culture methodology for analyzing PD fluid without loss of sensitivity. They also suggest that Gram stains are of relatively low yield; consideration could be given to ceasing their routine performance provided that broad antimicrobial therapy is administered pending culture results.<\/jats:p>","DOI":"10.3747\/pdi.2018.00087","type":"journal-article","created":{"date-parts":[[2019,3,11]],"date-time":"2019-03-11T20:59:20Z","timestamp":1552337960000},"page":"190-192","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":8,"title":["Performance of Gram Stains and 3 Culture Methods in the Analysis of Peritoneal Dialysis Fluid"],"prefix":"10.1177","volume":"39","author":[{"given":"Ruaridh","family":"Buchanan","sequence":"first","affiliation":[{"name":"Division of Infection Barts Health NHS Trust, Royal London Hospital Whitechapel Road, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stanley","family":"Fan","sequence":"additional","affiliation":[{"name":"Department of Nephrology Barts Health NHS Trust, Royal London Hospital Whitechapel Road, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caoimhe","family":"NicFhogartaigh","sequence":"additional","affiliation":[{"name":"Division of Infection Barts Health NHS Trust, Royal London Hospital Whitechapel Road, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2019,3,1]]},"reference":[{"key":"bibr1-pdi.2018.00087","doi-asserted-by":"publisher","DOI":"10.1177\/089686080902900314"},{"key":"bibr2-pdi.2018.00087","doi-asserted-by":"publisher","DOI":"10.1681\/ASN.2011121135"},{"key":"bibr3-pdi.2018.00087","doi-asserted-by":"publisher","DOI":"10.3747\/pdi.2016.00078"},{"key":"bibr4-pdi.2018.00087","doi-asserted-by":"publisher","DOI":"10.1016\/j.transproceed.2005.12.060"},{"key":"bibr5-pdi.2018.00087","doi-asserted-by":"publisher","DOI":"10.1111\/1469-0691.12402"},{"issue":"1","key":"bibr6-pdi.2018.00087","first-page":"1","volume":"2","author":"Ciesielczuk H.L.","year":"2012","journal-title":"J Med Microbiol Diagnostics"}],"container-title":["Peritoneal Dialysis International: Journal of the International Society for Peritoneal Dialysis"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3747\/pdi.2018.00087","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.3747\/pdi.2018.00087","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3747\/pdi.2018.00087","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T05:25:17Z","timestamp":1777613117000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.3747\/pdi.2018.00087"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,3]]},"references-count":6,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2019,3]]}},"alternative-id":["10.3747\/pdi.2018.00087"],"URL":"https:\/\/doi.org\/10.3747\/pdi.2018.00087","relation":{},"ISSN":["0896-8608","1718-4304"],"issn-type":[{"value":"0896-8608","type":"print"},{"value":"1718-4304","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,3]]}}}
