a dichotomous key is proposed for the identification of eight species of clostridium : clostridium botulinum , c. butyricum , c. haemolyticum , c. histolyticum , c. paraperfringens , c. perfringens , c. sporogenes y c. subterminale , on the basis of the gram staining , catalase production , growth on nutrient agar , glucose utilization , motility test , gelatin hydrolysis , lecithinase production , human blood hemolysis and the test of mice toxicity .
