Why do we need to perform microbial research in animals? Enormous amounts of microorganisms live both within and on animal, the animal and its microorganisms exchange energy substances, transmit information to each other and form a holistic system. The impact of microorganisms on animal health is mainly reflected in mutual benefit sharing and symbiosis. If […]
What is 18S rRNA? 18S ribosomal RNA (18S rRNA) is a component of the small eukaryotic ribosomal subunit (40S), and 40S and 60S constitute eukaryotic ribosomes. As a structural RNA for eukaryotic ribosomes, 18S rRNA, the homologue of 16S rRNA in prokaryotes and mitochondria, is thus one of the essential components of all eukaryotic cells. […]
As we all know that gut microbes provide multiple services to host, including digestion. Mammals with special diets, such as carnivores and anteaters, have special gut microorganisms to make it possible for them to eat such food. A common theme in the microbiome field is that the host diet has a significant impact on their […]
Every day we are dealing with countless microbes. But the latest research on a metagenomics shows that the microbial population on our skin surface is highly stable. These little guys are wrapping around us, like an invisible “little universe”. The bacteria, fungi and viruses on our skin are mostly harmless, and even healthy. But there […]
Researchers from St. Petersburg State University developed a method to improve the sequencing ability of DNA greatly, like life microbes in the human gastrointestinal tract or the ocean bacteria in a new study. This TruSPADES method assembles the short reads from the 300 base pairs of Illumina machine through computer into synthetic long reads. The […]
The concept of metagenome was proposed by Handelsman in 1998. It is the sum of DNA in a specific circumstance. Metagenomics is the research about the genome of micropopulation in the circumstance. It studies the microbial diversity, microbial population, evolutionary relationship, and its relationship with circumstance by structure functional gene screening and sequencing analysis. This […]
Metagenomics, basically speaking, is the study of genetic material recovered directly from environmental samples. In a broader sense, it can also be referred to environmental genomics, or ecogenomics. In traditional, cultivated clonal cultures were used most for microbiology and microbial genome sequencing. However, through those processes, a large number of microbial biodiversity had been missed. […]
