Hi doctor you have mentioned lecithinase activity is not there for clostridium perfringes then how it could produces Neagler reaction in egg yolk agar?

Hi Sam - I have to admit that you've stumped me! I'm going to have to refer back to a textbook as I don't have the answer immediately at hand...

@@therubinlab Nagler's reaction is a biochemical test used to identify organisms that liberate phospholipases (lecithinases) e.g. Clostridium perfringens. The alpha (α) toxin of C. perfringens has phospholipase activity and hence, helps in the differentiation of C. (This is what I read in my book)
