| Summary: | (1) Background: This paper aims to provide a description of non-faecalis non-faecium enterococci isolated from a tertiary care hospital in Romania and to briefly review the existing literature regarding the involvement of <i>Enterococcus raffinosus</i>, <i>Enterococcus durans</i> and <i>Enterococcus avium</i> in human infections and their antimicrobial resistance patterns; (2) Methods: We retrospectively analyzed all <i>Enteroccocus</i> species isolated from the “Prof. Dr. O. Fodor” Regional Institute of Gastroenterology and Hepatology from Cluj-Napoca during one year focusing on non-<i>faecalis</i> non-<i>faecium</i> Enterococci. A brief review of the literature was performed using case reports involving <i>Enterococcus raffinosus</i>, <i>Enterococcus durans</i> and <i>Enterococcus avium</i>; (3) Results: Only 58 out of 658 <i>Enteroccocus</i> isolates were non-<i>faecalis</i> non-<i>faecium</i> and met the inclusion criteria. These species were isolated more often (<i>p</i> < 0.05) from the surgical ward from mixed etiology infections with <i>E. coli</i>. In our review, we included 39 case reports involving <i>E. raffinosus</i>, <i>E. durans</i> and <i>E. avium</i>; (4) Conclusions: Isolation of non-<i>faecalis</i> non-<i>faecium</i> enterococci displays an emerging trend with crucial healthcare consequences. Based on the analysis of the case reports, <i>E. avium</i> seems to be involved more often in neurological infections, <i>E. durans</i> in endocarditis, while <i>E. raffinosus</i> displays a more heterogenous distribution.
