Salmonellae from Faeces of Domestic Animals

Abstract

A note in Nature, May 5, page 730, draws attention to the unreliability of killing the eggs of worms in faeces with formalin. A faecal specimen from a patient infected with Ascaris lumbricoides was preserved in hot 10% formalin in March, and when the specimen was examined in November many eggs were found containing motile Ascaris larvae. although the formalin concentration was still 6%.
