BACKGROUND Thermophilic campylobacters, particularly Campylobacter jejuni and C. coli are the main agents of human campylobacteriosis. Campylobacter contaminated chicken products is the most important source of foodborne gastroenteritis. Evaluation of genetic diversity among Campylobacter population is critical for understanding the epidemiology of this bacterium and developing effective contro...

BACKGROUND Appropriate methodology for storage biological materials, extraction of DNA, and proper DNA preservation is vital for studies involving genetic analysis of insects, bacteria, and reservoir hosts as well as for molecular diagnostics of pathogens carried by vectors and reservoirs. Here we tried to evaluate the utility of a simple filter paper-based for storage of insects, bacteria, rod...

Ancient chlamydiae diverged into pathogenic and environmental chlamydiae 0.7-1.4 billion years ago. However, how pathogenic chlamydiae adapted to mammalian cells that provide a stable niche at approximately 37 °C, remains unknown, although environmental chlamydiae have evolved as endosymbionts of lower eukaryotes in harsh niches of relatively low temperatures. Hence, we assessed whether an envi...

Herbaspirillum seropedicae is an endophytic diazotrophic bacterium, which associates with important agricultural plants. In the present study, we have investigated the attachment to and internal colonization of Phaseolus vulgaris roots by the H. seropedicae wild-type strain SMR1 and by a strain of H. seropedicae expressing a red fluorescent protein (DsRed) to track the bacterium in the plant ti...

Bacterial cellulose is produced by several species of Acetobacter and because of its unique properties; it has advantages over plant cellulose. Today, this biopolymer has numerous applications at many industrial fields. In this research, samples from different sources of Iran were collected and cultivated in an enrichment liquid medium for growth of acetic acid bacteria. After purification the ...

Advancement of Nucleic Acid-Based Tools for Monitoring In Situ Reductive Dechlorination Vangelas, K., E. Edwards, F. Loeffler, B.B. Looney. Paper No: WSRC-STI-2006-00332, 23 pp, Nov 2006 Regulatory protocols generally recognize that destructive processes are the most effective mechanisms that support natural attenuation of chlorinated solvents. In many cases, these destructive processes will be...

Tauco is one kind of traditional fermented food from Indonesia. processed soybean paste with a salty taste andcommonly has yellow and black color. Generally, tauco used as spice or seasoning in various daily dishes. The study aimsto find identify the bacteria that produced fibrinolytic enzymes tauco. sample this research sixdifferent manufacturers. Two tests have to do study: proteolytic test S...

Background and Aim: Prolonged stress causes deleterious effects on both the organism its microbiota. In this study, we examined of exposure to variable frequency ultrasound (US) gut microbiota-liver-brain axis mice. Materials Methods: This study was conducted 20 mature clinically healthy sexually naive C57BL/6J male mice (42–45 days old). Group 1 (Normal) consisted intact (n = 10). 2 (Stress) s...

Free fatty acid (FFA) is one of the pathogenic factors in acne vulgaris. However, how FFAs interact with skin microbiome and host immunity still unclear. To clarify this, we comprehensively investigated lesions developed a novel mouse model. First, measured severity amounts (C12-C24) healthy- acne-forehead (50 females, aged 20-40 years). The total palmitic (PA) were weakly correlated number inf...

Inflammatory bowel diseases (IBD) are chronic conditions arising from an intricate interplay of genetics and environmental factors, associated with gut dysbiosis, inflammation, permeability. In this study, we investigated whether the inflammatory potential diet is microbiota profile, permeability in forty patients IBD clinical remission. The dietary index (DII) score was used to assess diet. fe...
