a bacteriophage that regularly causes lysis of the bacteria that it infects; it may exist in one or the other of only two forms, vegetative or mature; it does not have a probacteriophage form (that is, its genome does not incorporate with that of the host bacterium), therefore it does not effect lysogenization.
