Abstract Purpose With antibiotic resistance (ABR) portrayed as an increasing burden to human health, this study reviews how and what extent toxicological impacts from use are included in LCAs supplement with two novel approaches include ABR, a consequence of use, into the LCA framework. Methods We review available studies that deal aspects antibiotics evaluate these have been characterized. The...
Abstract Background and objective: The effects of lactobacillus Species and their metabolites on dairy products were proved as probiotics on pathogenic bacteria. The aim of this study was to isolate the lactobacillus from dairy product (Yogurt, cheese, milk and whey …) and to determine the antimicrobial activity against some pathogenic bacteria (Salmonella typhimurium, E.coli, Helicobacter pyl...
ÐMicrobial pathogens are one of the major health risks associated with water and wastewaters. Current methods for the detection of pathogenic viruses, bacteria, protozoa and helminths tend to be inaccurate, time consuming and expensive. As a result, indicator bacteria are commonly used to determine the relative risk of faecal contamination and the possible presence of pathogens in water and was...
Organic fertilizers are the sources of many human-pathogenic microorganisms which potentially threaten the human health. This study was carried out to explore the possible effects of soil and manure types on filtration, transport and fate of manure-borne bacteria through undisturbed soil columns. The manure treatments consisted of cow manure, poultry manure and sewage sludge which were distribu...
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...

Backgrounds and Objectives:Total and Fecal coliforms (TC and FC), heterotrophic plate count (HPC), were counted by microbiological method and E.coli O157:H7 were detected through immunological and Real time PCRmethods inwater intake and all of units of Isfahanwater treatment plant (IWTP).Materials and Methods: The microbial profile including TC, FC, and HPC, were monitored and turbidity and tot...
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...
the antibacterial and antioxidant activities of methanol and acetone extracts of three marine algae, including hypnea hamulosa, gracilaria corticata and enteromorpha intestinalis wereinvestigated.antioxidant activities were determined by means of total antioxidant capacity, total phenolic compounds, dpph radical scavenging activity and ferric reducing antioxidant power. antibacterial activity w...
