title: Blood clearance of MS2 bacteriophage in Salmo trutta: a paradoxon.
abstract: A primary challenge of MS2 bacteriophage was cleared from the blood of the teleost Salmo trutta within 2.5 days. In contrast the clearance of a 2nd challenge required an extra 3.5 days and the induction of the secondary antibody response was delayed, though immune memory was observed later.
