Facklamia hominis is a rarely reported gram-positive coccus occasionally isolated from urine; only a few cases of F. hominis urinary infections (including pyelonephritis) have been documented. Because F. hominis resembles viridans streptococci and can be misidentified, it is likely underrecognized, and one report suggests it may be a facultative pathogen whose incidence could rise with better detection. Including F. hominis on the panel helps identify these rare UTI cases that would otherwise be missed (Pérez-Cavazos et al. 2022, Moreland et al. 2023).
