A. schaalii typically causes urinary tract infections, predominantly in the elderly. Here, we describe the first case of A. schaalii infection presenting as cellulitis and abscess in a patient with common variable immunodeficiency. The patient was successfully treated with an incision and drainage and a prolonged antibiotic course. A. schaalii infection should be considered in sterile abscesses, and anaerobic cultures should be requested in the absence of positive routine cultures.<\/jats:p>","DOI":"10.3390\/pathogens9060494","type":"journal-article","created":{"date-parts":[[2020,6,22]],"date-time":"2020-06-22T06:46:12Z","timestamp":1592808372000},"page":"494","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Actinotignum schaalii Abscess in a Patient with Common Variable Immunodeficiency"],"prefix":"10.3390","volume":"9","author":[{"given":"Christine Marie","family":"Panganiban","sequence":"first","affiliation":[{"name":"Division of Basic and Clinical Immunology, and Department of Pathology and Laboratory Medicine, University of California at Irvine, Irvine, CA 92660, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7422-1453","authenticated-orcid":false,"given":"Sudhir","family":"Gupta","sequence":"additional","affiliation":[{"name":"Division of Basic and Clinical Immunology, and Department of Pathology and Laboratory Medicine, University of California at Irvine, Irvine, CA 92660, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,6,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"899","DOI":"10.1099\/00207713-47-3-899","article-title":"Characterization of Some Actinomyces-Like Isolates from Human Clinical Specimens: Reclassification of Actinomyces suis (Soltys and Spratling) as Actinobaculum suis comb. nov. and Description of Actinobaculum schaalii sp. nov","volume":"47","author":"Lawson","year":"1997","journal-title":"Int.
