The
many usees of genotyping
Microbiology
tests
Microbiology laboratory tests are conducted in order to spot microorganisms
such as bacteria, parasites, fungi and viruses. Microbial testing results in
safer products that end up on the market, including food and food ingredients,
as well as agricultural products, water, cosmetics, fuels, pharmaceuticals,
among many others. These teats are very useful in the field of genotyping
because viruses and bacteria can be genotyped.
Molecular
biology lab methods
A molecular biology lab uses four basic methods in order to identify a variety
of different human and animal pathogens, such as blood, tissue, sputum, stools
and nasopharyngeal swabs. The first of these is called PCR or also known as a
polymerase chain reaction method that is used to target a specific gene for
amplification. There is also the method of serology which involves growing
specimens on certain media in order to obtain biochemical information. PFGE,
also known as the pulsed field gel electrophoresis method, involves analyzing
the size of DNA fragments obtained from organisms that were subjected to
enzymes that cut at certain sites within DNA. And the fourth method's known as
PulseNet, which is the use of uploaded data to aid in finding foodborne and
infectious disease case clusters.
The
procedures and benefits of genotyping
Genotyping finds differences in the genotype or genetic makeup of a person by
looking at their DNA sequence and comparing it to someone else's sequence, or
reference sequence. In short, genotyping uses DNA sequences to define
biological populations by utilizing molecular tools. It doesn't, however,
normally end up defining a person's genes but can reveal the genes inherited by
their parents. Molecular or forensic microbiology utilizes genotyping to help
control the spread of pathogens by finding the origin of outbreaks.
