peritoneal cells from donors immunized with the ria , ribosomal , or rna preparations ( i ) conferred maximal resistance to challenge 10 to 15 days after cell transfer and demonstrable resistance throughout the 45-day assay period , ( ii ) conferred resistance to infection when 10 ( 5 ) , 10 ( 3 ) , or 10 ( 2 ) peritoneal cells were injected subcutaneously but not with fewer than 10 ( 5 ) cells administered intraperitoneally , and ( iii ) rendered recipients capable of acting as donors of peritoneal cells that conferred demonstrable resistance on normal recipients .
