Abstract - Lysotypy and bacteriophage resistance of lactic mesophile sreptococci
164 strains of lactic mesophile Streptococci have been lysotyped by 79 bacteriophages. 10 lysotypic groups are defined. One bacteriophage lyses S. lactis. S. diacetylactis and S. cremoris.
69 wheys lyse 15 strains of industrial lactic mesophile streptococci. Bacteriophages classification of these french wheys are group VI, VIII, IX, X. Three strains are resistant against all the bacteriophages
