In this report, we present a 4-year-old female patient with Addison\u2019s disease and end-stage renal failure secondary to focal sclerosing glomerulosclerosis. Continuous ambulatory peritoneal dialysis had been performed, and 3 months later, the patient developed fever, diarrhea, and vomiting. Peritoneal fluid culture and dialysis fluid culture were positive for<jats:italic>W. virosa<\/jats:italic>. It was identified with Phoenix (BD, USA) and confirmed via 16S rRNA sequencing. It cannot be identified by Maldi Biotyper (Bruker). The isolate was found to be resistant to cephalosporins, ciprofloxacin, and amikacin by gradient test. Intraperitoneal cefepime was initiated but since antimicrobial susceptibility testing revealed cephalosporin resistance, therapy was changed to intraperitoneal meropenem. Following the removal of peritoneal dialysis catheter, fever, abdominal distention, and vomiting were resolved. Piperacillin, aztreonam, and carbapenems can be used for empirical therapy. Antimicrobial susceptibility testing should be performed to guide the choice of treatment. Removal of peritoneal dialysis catheter is an important step of management of this infection. To our knowledge, this is the first report of<jats:italic>W. virosa<\/jats:italic>in a pediatric patient and first report from Turkey.<\/jats:p>","DOI":"10.1556\/030.66.2019.027","type":"journal-article","created":{"date-parts":[[2019,12,9]],"date-time":"2019-12-09T09:10:28Z","timestamp":1575882628000},"page":"62-64","update-policy":"http:\/\/dx.doi.org\/10.1556\/policypage.crossmark.crossref.1","source":"Crossref","is-referenced-by-count":3,"title":["An unusual case of peritoneal dialysis-associated bacterial peritonitis caused by Weeksella virosa"],"prefix":"10.1556","volume":"68","author":[{"given":"Tugce","family":"Unalan","sequence":"first","affiliation":[{"name":"1Faculty of Medicine, Department of Medical Microbiology, Hacettepe University, Ankara, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alper","family":"Karagoz","sequence":"additional","affiliation":[{"name":"2Faculty of Molecular Biology and Genetics, Department of Microbiology, Usak University, Usak, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cihangul","family":"Bayhan","sequence":"additional","affiliation":[{"name":"3Faculty of Medicine, Department of Pediatric Infectious Diseases, Hacettepe University, Ankara, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yasemin","family":"Ozsurekci","sequence":"additional","affiliation":[{"name":"3Faculty of Medicine, Department of Pediatric Infectious Diseases, Hacettepe University, Ankara, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gulsen","family":"Hazirolan","sequence":"additional","affiliation":[{"name":"1Faculty of Medicine, Department of Medical Microbiology, Hacettepe University, Ankara, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"425","reference":[{"key":"ref01","doi-asserted-by":"crossref","first-page":"155","DOI":"10.1093\/ajcp\/54.2.155","article-title":"Nonfermentative bacilli associated with man.
