Abstract
Methods of maintaining and feeding and of infecting cockroaches with pathogenic organisms were investigated.
Cockroaches fed on known concentrations of Escherichia coli O119, Esch. coli O1, Alkalescens Dispar O group 2 and Shigella dysenteriae 1 (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 gruel Esch. coli O119 was isolated for up to 20 days, Esch. coli O1 for 17 days and ADO 2 for 15 days. Sh. dysenteriae 1 was isolated only sporadically to the third day.
