Abstract Effects of enzymatic and microbial feed supplements on fecal pathogen shedding were tested in a 2×2 factorial, randomized complete block design, where the experimental unit (n = 20) was pen 3 lambs. Lambs blocked (i =10) by weight then randomly assigned within to phase 1 treatments control (C) or enzyme product (E). Upon acclimation diet, pens treated daily as E (1.1 g per animal Maxim...
During the last two decades, various medicinal plants have been studied for their possible antimicrobial activity to discover new antimicrobial agents capable of resolving problems such as the development of drug resistance in pathogenic microorganisms as well as the side effects of some present antibiotics. In this study, the antibacterial activity of methanolic extract of T. pubescens (rich i...
abstract in aggregate, active forms of reactive silica with mineral names are sometimes associated with sand and gravel in concrete mixture. alkali hydroxides originated from alkalis in the cement or other resources form an alkaline silica gel with this reactive silica which becomes swallowed and expanded during time causing damage to concrete. there have been growing researches on alkaline r...
abstract the problems caused by the traditional system of criminal justice (which are based on remuneration and rehabilitation) such as, lack of attention to victim’s rights and position and society, underlie the emergence of restorative justice which had the victim-centered perspective, with respect to the role of the offender and participation of civil society. meanwhile, criminal mediation ...
Background and purpose: Wild rats are considered as an important spreading factor of contamination in urban areas. During recent years, the wild rats were extensively distributed in Tehran. Therefore, it is important to investigate the antibiotic resistance of enteric bacteria isolated from rats, because of the possibility of antibiotic resistance transmission to human. The aim of this study ...
Background: Dendrimers are a subset of branched structures that have certain structural order. The aim of this study was to investigate the performance of Nano Polyamidoamine–G5 (NPAMAM-G5) dendrimers in removal of Escherichia Coli, Salmonella Typhi, Shigella Dysenteriae and Bacillus Subtilis from aqueous solution. Material and methods: In this experimental study, initially dilut...
Compost tea (CT) is an unheated on-farm infusion of compost used as a spray or soil drench to promote plant growth and control foliar and root diseases. Because food safety involves all aspects from farm to fork, CT should meet basic microbiological criteria for water quality. This report describes the effects of two CT production processes, aerated and nonaerated, on growth and survival of foo...

Background and Aims: Marine Actinomycetes are gram-positive bacteria that sometimes are free, saprophytic or plant and animal-associated, including marine sponges. More than 75% of antibiotics and antimicrobial compounds are produced by actinomycetes. In recent years, due to the need for new drugs, marine microorganisms have been considered as new sources of potential production of significant ...
