Discusses the interaction between socio-economic systems and their natural environment, by examining the indicators of sustainable development. Areas covered by the operationalization of sustainable development indicators; Details on the global nature of environmental problems; Important strategy of the operationalization of sustainable development; Link between economic data and ecological ind...

198 Lactic acid bacteria (LAB) were isolated from Iranian milk samples. Almost all isolatedLAB showed inhibitory activity towards E. coli and S. aureus as Gram negative and Grampositive indicators, respectively. No role was observed for hydrogen peroxide in the activity ofall isolated strains while organic acids proved a prominent role in all detected inhibitoryactivities. Within isolated LAB, ...

Studies of the occurrence and survival of sewage-origin bacteria in coastal waters and sediments continued this year at the marine microbiology laboratory at California State University at Long Beach. The goal of these studies has been to determine what relationships, if any, exist between the routinely sampled indicator bacteria (e.g., coliforms, fecal streptococci) and pathogenic bacteria (e....

The potential for a revolution in microbial testing can be perceived with the near on-line detection of indicator microorganisms. By definition, these are microorganisms present in significant numbers within a food which, while not pathogenic, can be related through increasing count to the increased probability of pathogen contamination. We have used recombinant lux+ bacteriophage to detect ent...

Occurrence of antimicrobial resistant bacterial strains is a key issue for therapeutic outcome both in human and veterinary medicine. Moreover, when considering food animals the risk of their contribution to antibiotic resistance in humans has to be taken into account. Consequently surveys are needed to describe evolution of drug sensitivity in pathogens and indicator bacteria obtained from the...

An inevitable side effect of the use of antibiotics is the emergence and dissemination of resistant bacteria. Most retrospective and prospective studies show that after the introduction of an antibiotic not only the level of resistance of pathogenic bacteria, but also of commensal bacteria increases. Commensal bacteria constitute a reservior of resistance genes for (potentially) pathogenic bact...
