Since the division of the Streptococcus genus into enterococci, lactococci, and streptococci in 1984, many changes in the nomenclature and taxonomy of the Streptococcus genus have taken place. The application of genetic comparisons has improved the proper classification of the different species. Infections commonly caused by enterococci include urinary tract infection (UTIs), endocarditis, bacteremia, catheter-related infections, wound infections, and intra-abdominal and pelvic infections. Many infecting strains originate from the patient's intestinal flora. These organisms were previously considered part of the genus Streptococcus but have recently been reclassified into their own genus, called Enterococcus. To date, 12 species pathogenic for humans have been described, including the most common human isolates, Enterococcus faecalis and E. faecium. 1 The reference used for compiling the methods in Section I is: Murray, P.R., Baron, E. J., Jorgensen, J.J., Pfaller, M.A., and Yolken, R.H. Manual of Clinical Microbiology, 8 th ed. ASM Press: Washington, DC, 2003. The Streptococcus species identification methods in Section II were compiled by Dr. Lynn Shewmaker. Background. Enterococci are part of the normal intestinal flora of humans and animals. They have been long recognized as important human pathogens and are becoming increasingly so. The genus Enterococcus includes more than 17 species, although only a few cause clinical infections in humans. The genus streptococcus is comprised of many species of Gram positive cocci arranged in chains. They are distinguished from the other major genus of Gram-positive cocci – Staphylococcus by their cellular arrangement and their inability to produce the enzyme catalase. Streptococci are facultatively anaerobic, Gram-positive organisms that often occur as chains or pairs (figures 1 and 2) and are catalase-negative (in contrast, staphylococci are catalase positive) (figure 3). Streptococci are subdivided into groups by antibodies that recognize surface antigens (figure 4). Enterococci can also cause urinary tract infections; intraabdominal, pelvic, and wound infections; superinfections (particularly in patients receiving expanded-spectrum cephalosporins); and bacteremias (often together with other organisms). They are now the third most common organism seen in nosocomial infections. 1 If the culture is an unidentified gram-positive coccus, an Enterococcus, viridans Streptococcus, or of unknown identity (basically includes all cultures other than pneumococci, ss-ß hemolytic, streptococci and nutritionally variant), streptococci inoculate the following.  media
