Lactococcus lactis catheter-related bloodstream infection in an infant: case report.

LACTOCOCCUS LACTIS CATHETER-RELATED BLOODSTREAM INFECTION IN AN INFANT: CASE REPORT. Jpn J Infect Dis. 2014 Dec 24; Authors: Karaaslan A, Soysal A, Sarmış A, Kadayifci EK, Cerit K, Atıcı S, Söyletir G, Bakır M Abstract Lactococcus lactis is a gram-positive coccus that is nonpathogenic in humans. Herein, we present the case of a one-year-old boy with Down's syndrome (DS) and Hirschprung's disease (HD) who developed a catheter-related bloodstream infection (CR-BSI) with L. lactis after gastrointestinal surgery. The patient had been hospitalized in the pediatric surgery unit from birth because of the HD, and he had undergone the Duhamel-Martin procedure which caused recurrent diarrhea episodes and feeding intolerance. On the 430th day of life, the infant had an episode of gastroenteritis and feeding intolerance. Because clinical sepsis was suspected, blood cultures were taken both from the central venous catheter and peripheral vein, and evidence of a growing microorganism was detected in two different central venous catheter blood cultures that were taken two days apart. The colonies were then identified by both the Vitek2 and VitekMS system (bioMérieux) as Lactococcus lactis spp. lactis. Afterwards, we realized that the central venous catheter could not be removed because there was no peripheral venous line, and the patient was subsequently treated successfully with vancomycin. Therefore, even though the Lactococcus species is ...
