in the present study a new economic and rapid bacterial micro-assay for simultaneous detection and quantitative measurement of serum galactose was developed. analysis of the standard curve showed a linearity range for galactose from 2 mg/dl to 180 mg/dl with a regression equation of y = 0.013x ? 0.083; r² = 0.962. the advantage of the method is its ability to measure serum galactose quantitativ...

background: yogurt is one of the most popular food diets with refreshing taste, nutritional, and health benefits. the objective of this study was to investigate the effect of three herbal essential oils (eos) including peppermint, basil, and zataria on viability of the probiotic bacteria in yogurt samples and to evaluate the antimicrobial activities of the produced probiotic yogurts against esc...

background: multidrug resistant enterobacteriaceae which was confined to the hospital environments is now emerging in the domestic food related environments as well. the main objective of the present study was to investigate the prevalence of antibiotic resistant enterobacteriaceae in the domestic food related environments.  methods: resistance to ampicillin, chloramphenicol, ciprofloxacin, gen...

background hygiene and maintenance of removable prostheses are very important for the oral health. elderly patients are not capable of this affair since they might have diseases in addition to being old; thus, they require new alternative methods. objectives the purpose of this study was to compare the disinfecting effects of three substances, water, normal saline and denture cleaning tablets c...

pantoea ananatis is an important pathogen causing bacterial center rot in onion. isolated strains from onion soft rot bulbs based on morphological characteristics were tested for hypersensitivity reaction on tobacco. pathogenic strains underwent some biochemical tests which detected the presence of p. ananatis, based on rna16s sequencing, this result was confirmed. symptoms were reproduced by i...

background nafld/nash is a manifestation of metabolic syndrome and is associated with obesity/overweight. not all obese/overweight individuals develop nash. gastro-esophageal reflux disease (gerd) is considered a gastrointestinal manifestation of the metabolic syndrome and is associated with obesity/overweight. again not all obese/overweight individuals develop gerd. recent data show associatio...

introduction: the purpose of this study was to evaluate the sealing ability of 3 obturation techniques in oval-shaped canals by bacterial leakage assessment. methods: sixty mandibular incisors with oval canals were selected after providing buccolingual and mesiodistal radiographs. the teeth were sectioned at a 10 mm distance from the apex. after instrumentation, the teeth were divided into 3 gr...

patients and methods the study population consisted of all patients with type iiia gastilo open fractures of tibial shaft, with or without fibula fracture (caused by trauma). after wound irrigation, debridement, and wound swab sampling for microbial culture, all patients received prophylactic antibiotic regimens in fitting with their wound class. no topical antibiotics were used with a 6-month ...

the intestinal bacterial diversity of stichopus japonicus was investigated using 16s ribosomal rna gene (rdna) clone library and polymerase chain reaction/denaturing gradient gel electrophoresis (pcr-dgge). the clone library yielded a total of 188 clones, and these were sequenced and classified into 106 operational taxonomic units (otus) with sequence similarity ranging from 88 to 100%. the cov...

yeasts, especially saccharomyces cerevisiae, are one of the oldest organisms with broad spectrum of applications, owing to their unique genetics and physiology. yeast extract, i.e. the product of yeast cells, is extensively used as nutritional resource in bacterial culture media. the aim of this study was to develop a simple, rapid and cost benefit process to produce the yeast extract. in this ...
