Abstract
SUMMARYMethods of maintaining and feeding and of infecting cockroaches with pathogenic organisms were investigated.Cockroaches fed on known concentrations ofEscherichia coli0119,Esch. coliO1, Alkalescens Dispar O group 2 andShigella dysenteriae1 (Shiga's Bacillus) were maintained in Petri dishes. The effect of various diets on the survival of these organisms within the hind-gut and faeces was observed. With a ‘normal’ diet of gruelEsch. coli0119 was isolated for up to 20 days,Esch. coliO1 for 17 days and ADO 2 for 15 days.Sh. dysenteriae1 was isolated only sporadically to the third day.
