Two experiments were carried out to study the effects of dietary supplementation with the garlic (Allium sativum)-derived product propyl propane thiosulfonate (PTS-O) on the intestinal log(10) number of copies of enteropathogens in broiler chickens, together with their intestinal morphology and growth performance. The additive had no significant effect on feed intake at any dose assayed. In exp...

the effects of essential oils (eos) of oregano and nutmeg with and without commercial emulsifier/stabilizer compound (e/s) on the microbial quality of ready-to-cook barbecued chicken were evaluated. barbecued chicken was traditionally prepared. 3 μl/g and 10 mg/g of eos and/or e/s were then added to the barbecued chicken, respectively. the samples were stored at 3°c for 144 h, 8 and 20ºc for 72...

this study was conducted to compare the effect of various commercial in-feed disinfectants on layer performance, intestinal microflora, and egg cholesterol. one hundred and eight layer hens (lsl, 24 wks of age) were divided into six groups consisting: control, formaycin-200 ppm, formalin-200 ppm, and nanosilver in feed-15 ppm or drinking water-7.5 ppm. there were no differences between experime...

In order to identify possible risk factors for microbial keratitis the storage cases for contact lenses of 102 asymptomatic lens wearers were tested for contamination by bacteria and free-living amoebae. Of this group 43 had significant counts of viable bacteria and only 40 had negligible counts. Seven had contamination by acanthamoebae, of whom six also had significant bacterial counts. These ...

16S ribosomal RNA (rRNA) gene and other environmental sequencing techniques provide snapshots of microbial communities, revealing phylogeny and the abundances of microbial populations across diverse ecosystems. While changes in microbial community structure are demonstrably associated with certain environmental conditions (from metabolic and immunological health in mammals to ecological stabili...

A newly developed rapid microbial ATP bioluminescence test (R-mATP) was shown to be an adequate means to assay the microbial load of poultry carcasses. This assay utilizes differential extraction and filtration to separate somatic from microbial ATP in a very rapid timeframe. The assay requires approximately 5 min to complete; approximately 3.5 min to sample and 90 s analytical time. Correlatio...

Background; Providing Safe drinking water is a prime concerninany community. This analytical study was carried out to evaluate the microbial quality of drinking water in rural areas of northeastern Iran. Methods;The water microbial quality was determined in all villages (a population of 53047 people), in 3 rounds and based on 3 measurements, i.e. Total Coliform, Fecal Coliform, and Heterotro...

In this work effects of gamma irradiation and storage time on microbial decontamination of fresh camel meat stored at 4 ̊C were evaluated. Microbial analysis indicated that irradiation had a significant effect on the reduction of microbial loads. Among the analyzed bacteria, coliforms were most sensitive to gamma radiation. Considering the sensory analyses and Total bacterial counts analyses as ...
