Abstract

On the basis of pigment production on brain heart infusion agar medium containing crocin, differentiation of mastitic streptococcus was investigated. Intensive crocin reaction was showed in braille heart infusion agar when maximum volume of gardenia powder was 5.0 mg/ml and dark-violet pigmentation of Str. uberis and Group D (Str. facalis) Streptococcus were differentiated from negative strains of Str. dysgalactiae. Also, although most of Str. agalactiae was producted pigment, a few was not affected with the crocin reaction.
