<prompt> Naeglers reaction is used for:Cl. TetaniCl. BotulinumCl. PerfringensCl. Septicum  <response>: Naglers reaction Naglers reaction is an example of Neutralization test done for detection of a toxin lecithinase produced by C. perfringens. The alpha toxin of C. perfringens has phospholipase activity , when grown on a medium containing egg yolk phospholipid, the organism can break this insoluble triglyceride. Phosphoryl choline release is seen as an area of opacity around the bacterial colonies. Antitoxin can inhibit a positive Naglers response.
