  1. 1Total number of turkeys/treatment group (row), 2Age in days at Eimeria meleagrimitis-inoculation, 3 Number (in thousands) of Eimeria meleagrimitis oocysts inoculated per bird. Strain pM3 was used in experiments 1–8, strain USSMN08–01-5 was used in experiment 9, 4 CP = Clostridium perfringens, Days = number of days between Eimeria meleagrimitis-inoculation and Clostridium perfringens-inoculation, 5 Number of hours between Eimeria meleagrimitis-inoculation and post-mortem examination, 6 Number of birds with the appropriate score (NE = mucosal pseudomembrane, ulcer or depression, score3 = score 3 in the scoring system) on each sampling occasion after Eimeria meleagrimitis-inoculation, 7 Mean score on each sampling occasion
