“…The growth was re-ingested by the cockroach, defaecated onto a new plate, re-ingested and so on until eventually the concentration of S. marcescens appeared to kill the cockroach. This organism is present in the normal gut flora of some 6 % of the insects used (Burgess, McDermott & Whiting, 1973), and under certain circumstances might present a means of biological control. In low concentrations the organism will probably fail to survive in the gut, but at higher concentrations the defence mechanism of the cockroach may be overwhelmed.…”

SUMMAlRYMethods of maintaining and feeding and of infecting cockroaches with pathogenic organisms were investigated.Cockroaches fed on known concentrations of Escherichia coli 0119, Esch. coli 01, Alkalescens Dispar 0 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 0119 was isolated for up to 20 days, Esch. coli 01 for 17 days and ADO 2 for 15 days. Sh. dysenteriae 1 was isolated only sporadically to the third day.

SUMMARYA total of 221 cockroaches (BlattaandPeriplanetaspp.), collected in hospitals, houses, animal sheds, grocery stores and restaurants, in yarious parts of South Kanara District, a south-west coastal region of India, were studied bacteriologically for the presence of various salmonellas. Salmonellas were isolated from 4·1% of these cockroaches. Nine strains of salmonellas were recovered, belonging to five serotypes –Salmonella bovismorbificans, S. oslo, S. typhimurium, S. mbandakaandS. braenderup, the former two being the commonest serotypes. All salmonellas were resistant to one or other of 11 antibacterial drugs used in the susceptibility test. Isolation of salmonellas from cockroaches collected from the livestock premises and human dwellings suggested that they may act as significant reservoirs of salmonella in nature. Recovery of serotypes, phage types and R- types that were commonly isolated from humans and animals of this locality, suggested a transmission role for cockroaches. By harbouring potentially pathogenic, drug-resistant salmonellas, these wandering arthropods may pose dangerous infective hazards to humans and animals.

From Waste to Plastic: Synthesis of Poly(3-Hydroxypropionate) in Shimwellia blattae

bIn recent years, glycerol has become an attractive carbon source for microbial processes, as it accumulates massively as a byproduct of biodiesel production, also resulting in a decline of its price. A potential use of glycerol in biotechnology is the synthesis of poly(3-hydroxypropionate) [poly(3HP)], a biopolymer with promising properties which is not synthesized by any known wild-type organism. In this study, the genes for 1,3-propanediol dehydrogenase (dhaT) and aldehyde dehydrogenase (aldD) of Pseudomonas putida KT2442, propionate-coenzyme A (propionate-CoA) transferase (pct) of Clostridium propionicum X2, and polyhydroxyalkanoate (PHA) synthase (phaC1) of Ralstonia eutropha H16 were cloned and expressed in the 1,3-propanediol producer Shimwellia blattae. In a two-step cultivation process, recombinant S. blattae cells accumulated up to 9.8% ؎ 0.4% (wt/wt [cell dry weight]) poly(3HP) with glycerol as the sole carbon source. Furthermore, the engineered strain tolerated the application of crude glycerol derived from biodiesel production, yielding a cell density of 4.05 g cell dry weight/liter in a 2-liter fedbatch fermentation process.
