RESUMO
The United Kingdom is within the geographical area in which Aedes albopictus could survive. A large number of used car tyres are imported and a number of introduced cases of dengue fever occur annually. The health authorities should be aware of the possibility of dengue transmission.

Aedes albopictus is an important and widespread vector of dengue in many tropical countries. Its eggs and larvae are readily transported in commodities, such as old vehicle tyres, to many temperate regions, where it is able to survive and breed. It could thus become a serious health threat in Europe.

Methods are described for the isolation and identification of aerobic bacteria occurring naturally in the hind-gut of the cockroach Blatta orientalis captured from a number of wild sources, to establish whether or not human pathogens occurred naturally within the gut. During the investigation an organism was frequently found which could not be classified in any described species, and for which we propose the name Escherichia blattae.

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.
