To acquire further insight into microbial variation of normally occurring bacterial population in defined biological niches, it is important to look closely at the physiology of the particular niche [ 3].
This study highlights some cornerstones of microbial variations in healthy and diseased paranasal sinuses.
The combination of WGA and DGGE analysis successfully monitored oropharyngeal microbial variations, and established that oropharyngeal microbiome of each subject maintained a relatively stable composition during the follow-up.
Whole genome amplification combined with denaturing gradient gel electrophoresis analysis monitored successfully oropharyngeal microbial variations and showed that the composition of each subject's oropharyngeal microbiome remained relatively stable during the follow-up.
The largest component of microbial variation corresponded to the carriage (or absence) of Prevotella, which significantly differentiated NORA subjects from healthy controls and other forms of arthritis.
Study components were as follows: (1) determination of the temporal stability of the oropharyngeal microbiome; (2) identification of oropharyngeal microbial variation in 90 subjects; (3) quantitative identification of disease-associated bacteria.
Studies of the microbial communities in healthy humans and laboratory animals implicate microbial variation as a factor influencing everything from nutrient extraction during digestion, to defense against invading pathogens, to the ability to inactivate environmental toxins.
In this experiment, we found that temperature and the OMCs, as well as the variations of microbial community and physicochemical parameters, were all correlated to zinc leaching efficiency.
Previous studies in this river network indicated that variations of microbial communities were the major factor affecting the distribution of antibiotic resistant genes highlighting the importance of understanding controls of microbial communities.
The MEC performance as an energy carrier generator was characterized based on the hydrogen production rate evolution, the variations of microbial distributions, and methane production at different applied potential differences.
