Molecular Microbial Ecology of the Gastrointestinal-Tract

چکیده
During the past decade it became evident that anaerobic cultivation-based approaches provides an incomplete picture of the microbial diversity in the GI tract, since at present only a minority of microbes can be obtained in culture. The application of molecular, mainly 16S ribosomal RNA (rRNA)-based approaches enables researchers to bypass the cultivation step and has proven its usefulness in studying the microbial composition in a variety of ecosystems, including the gastrointestinal (GI) tract. This critical review summarizes the impact of these culture-independent approaches on our knowledge of the ecology of the GI tract and provides directions for future studies which should emphasize function of specific strains, species and groups of microbes.

Molecular microbial ecology in gut ecosystems
The microbial community inhabiting the gastrointestinal tract is represented by all major groups of microbes and is characterized by high population density, wide diversity and complexity of interactions. Resident microbial populations have been described as herbivores, omnivores, carnivores, and in a wide range of zoological classes where they contribute to the nutrition, physiology, immunolog...

It is now generally accepted in microbial ecology that cultivation-based approaches provide an incomplete picture of microbial diversity in the gastrointestinal (GI) tract because only a minority of microbes can be obtained in culture. Therefore, the application of molecular approaches, especially those focused on 16S ribosomal RNA (rRNA) sequence diversity, have become popular as they enable r...

Primary Malignant Melanoma of the Gastrointestinal Tract: Report of Two Cases
Although gastrointestinal involvement by metastatic malignant melanoma is common but primary gastrointestinal (GI) melanoma has been reported in rare cases. In this study we report two cases of primary gastrointestinal malignant melanoma that one of them is a known case of neurofibromatosis type 1(NF1). Both cases showed no evidence of any lesions in skin and eye. Malignant melanoma of GI tract...

All animals, including humans, are adapted to life in a microbial world. Anaerobic habitats have existed continuously throughout the history of the earth, the gastrointestinal tract being a contemporary microniche. Since microorganisms colonize and grow rapidly under the favorable conditions in the gut they could compete for nutrients with the host. This microbial challenge has modified the cou...
