First Report of Human Urinary Tract Infection Caused by .

is a recently described species of the genus . It was reported as an etiological agent of piscine lactococcosis together with . was already described as an opportunistic pathogen in human infections, with a potential zoonotic role. This paper represents the first report of a human urinary tract infection caused by . A 91-year-old man was admitted to the emergency department for a femur fracture consequent to a domestic accident. The fracture was reduced by surgery and a catheterized specimen urine culture revealed a high bacterial load sustained by Gram-positive cocci, identified by Vitek 2 compact as , and subsequently as through Internal Transcribed spacer 16S-23S r-RNA amplification. The number of infections in humans is expected to rise in the near future mainly due to diagnostic improvement. A dedicated survey on and infections in humans should be performed to better understand their role as pathogens and as zoonotic agents.
