<prompt> Nagler reaction is type of -Neutrilization reaction is type of -CFTPrecipitationAgglutination  <response>: Its a neutralization test. Lecithinase test or Naglers reaction is a biochemical test used to identify organisms which liberate phospholipases lecithinases e.g. Clostridium perfringens. The alpha a toxin of C. perfringens has phospholipase activity and hence, helps in differentiation of C. perfringens from other Clostridium spp that also produce lecithinase C.baratti, C.absonum, C.bifermantans, C.sordelli and C.novyi by neutralization of lecithin c activity by an antitoxin.
