“…Clinical Phage and bacteriocin typing have been applied to enterococci at various times over the past two decades (33,109,115,166,167,212). A recent publication reported a typing scheme, using both phage and enterococcines, with over 900 enterococci from two hospitals (114).…”

Enterococci are important human pathogens that are increasingly resistant to antimicrobial agents. 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. Enterococci cause between 5 and 15% of cases of endocarditis, which is best treated by the combination of a cell wall-active agent (such as penicillin or vancomycin, neither of which alone is usually bactericidal) and an aminoglycoside to which the organism is not highly resistant; this characteristically results in a synergistic bactericidal effect. High-level resistance (MIC, greater than or equal to 2,000 micrograms/ml) to the aminoglycoside eliminates the expected bactericidal effect, and such resistance has now been described for all aminoglycosides. 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. For most of these infections, single-drug therapy, most often with penicillin, ampicillin, or vancomycin, is adequate. Enterococci have a large number of both inherent and acquired resistance traits, including resistance to cephalosporins, clindamycin, tetracycline, and penicillinase-resistant penicillins such as oxacillin, among others. The most recent resistance traits reported are penicillinase resistance (apparently acquired from staphylococci) and vancomycin resistance, both of which can be transferred to other enterococci. It appears likely that we will soon be faced with increasing numbers of enterococci for which there is no adequate therapy.

“…The production of bacteriocine-like substances by streptococci of several Lancefield groups has been described: group A (Sherwood et al, 1949;Kuttner, 1966;Overturf and Mortimer, 1970;Kolesnichenko and Totolyan, 197 1;Prakash, Ravindran and Sharma, 1973;Tagg, Read and McGiven, 1973a); group B (Kuttner, 1966;Kramer and Brandis, 1972;Prakash et al, 1973;Tzannetis, Poulaki-Tsontou and Papavassiliou, 1974;Tagg, Dajani and Wannamaker, 1975); and group D (Brock, Peacher and Pierson, 1963;Tzannetis, Leonardopoulos and Papavassiliou, 1970;Kekessy and Piguet, 1971;PleceaS, Bogdan and Vereanu, 1972). Typing schemes have been established for the differentiation of group-D streptococci on the basis of their production of (Tzannetis et al, 1970) and sensitivity to (PleceaS et al, 1972) bacteriocine-like substances or both (Kekessy and Piguet, 1971).…”

“…Considerable information has now been accumulated regarding the structure, genetics, and mode of action of bacteriocins, particularly those of gram-negative organisms (22). Although the production of bacteriocin-like inhibitory effects has been demonstrated in a wide variety of different streptococcal strains (18), the only streptococcal bacteriocins to be isolated and characterized have been those produced by group D organisms (2,29).…”
