Abstract

Two strains of vancomycin-resistant Leuconostoc species were isolated from blood cultures in two compromised patients. The isolates produced gas from Lactobacillus MRS booth, hydrolysed esculin, and produced no ammonia from arginine, thus fulfilling the major criteria as Leucorostoc spp. We recommend that clinical laboratories should perform susceptibility test to vancomycin for clinical isolates (especially from cerebrospinal fluid and blood) which resemble streptococci so as not to confuse Leuconostoc spp. with more commonly isolated pathogens such as streptococci.
