A Report of Two Cases of Bacteremia by Leuconostoc lactis in Immunocompromised Patients

Abstract Background Leuconostoc lactis (L lactis) are gram positive cocci and generally considered to be environmental organisms. They were widely regarded as non-pathogenic and therefore of limited clinical significance. Molecular identification is one technique to identify bacteria.Case reports We presented two cases of bacteremia caused by L lactis. They were both advanced age, history of various diseases, intravenous catheter implantation, parenteral nutrition, longer hospital stay and using of multiple antibiotics. The 16S rRNA genes of the isolates of these two patients´ blood were sequenced. Conclusions When immunocompromised patients with risk factors develop bacteremia caused by L lactis, adequate attention and effective treatment measures should be given.
