ABSTRACT
Number of enterococci determined in raw milk cistern samples was in range of 2.95 to 4.18 log CFU.ml-1 and raw milk samples obtained from storage tanks contained enterococci count in the range of 3.04 to 4.51 log CFU.ml-1. Results of microbiological quality evaluation showed, that count of enterococci increased during cold storage of raw milk. Portion of enterococci from the total microflora of raw milk taken from cistern samples was 0.44 %, otherwise in raw milk samples taken from storage tanks portion of enterococci decreased to 0.38 %. Among enterococci isolates  E. faecalis was the predominat species in tested samples of raw milk from both cistern – 58.1 % and storage tank – 71.7 %. The following species were identified E. faecium, E. group III., E. mundtii, E. casseliflavus. It was found that 38 % E. faecalis isolates were able to form a biofilm.doi:10.5219/200
