Abstract
Lactococcus spp. is typically thought to be of low virulence and seldom considered pathogenic. Few cases of significant infections in children have been reported, all outside of the United States. There is also limited data on antimicrobial susceptibility testing for Lactococcus spp. We present three pediatric patients with central line bloodstream infections due to Lactococcus spp. between 2018 and 2020, along with a review of the pediatric literature.
