centuries, terms such as bacteria, viruses, and germs have gained a bad
reputation due to their affiliation as disease causing agents
(pathogens). Astonishingly, these microbes remain essential to human
life. Mixing the good and the bad, only a tiny fraction of the million
microbes found in Earth's vast environment classify as "harmful". Therefore the rest are helpful and essential to life.
A new and exciting field named metagenomics studies the genomic analysis of microorganisms in the environment. This field allows the study of microorganisms extracted from the environment samples, bypassing the need for traditional cultural methods. Metagenomics allows the study of 99% of microorganisms that cannot be cultured or studied.
Since traditional genomic analysis can only take us so far; issues such as non-cultivable microbes and need of genomic diversity analysis creates the demand for the metagenomic field.
Metagenomics, claims its rightful place as an impressive, promising, and rich new field due to it's ability to provide new and revolutionizing information.
