  1. a Bacterial growth from at least one of the maediastinal organs, blood or steel wire has been taken as presence of infection.
  2. * Differences between groups: rate of growth from the steel wire pieces between B and D; P = 0.005, rate of growth from steel wire pieces between C and D; P = 0.019, rate of total growth between A and C; P = 0.027, rate of total growth between A and D; P = 0.005, rate of total growth between B and C; P = 0.027, rate of total growth between B and D; P = 0.005.
