An outbreak of disease associated with cryptosporidia on a red-legged partridge (Alectoris rufa) game farm is described. Morbidity (diarrhoea and cough) was between 60 and 70% during the first weeks of life (4 to 25 days) and mortality was higher than 50%. The results of bacteriological and virological analyses were negative. Histological examination and antigenic diagnosis by ELISA revealed the presence of Cryptosporidium spp. in respiratory and intestinal tracts. The application of PCR-RFLP
