Abstract: Escherichia coli (E.coli) is a common
bacteria that colonize digestive truck of many organisms
including humans and is a important source of Vitamin K
and B12. However, numerous strains of E.coli are
pathogenic and cause severe infections and alimentary
toxemia. Eight toxic strains of E.coli are known till
now. The main source of E.coli infections is water. That
is why monitoring the purity level of water sources is
extremely important for public health. Commonly used
methods for E.coli detection are time-consuming and rely
on E.coli culturing and cells differentiation.
Noticeably faster and more sensitive method for E.coli
detection is a PCR where even small copy of E.coli
genome might be detected. What is more, the analysis can
be done in about one hour, what accelerate the time of
analysis.
PCR (Polymerase Chain Reaction) is sensitive and
specific tool for DNA fragments amplification and
utility of this technique is still growing. Here we are
presenting a device dedicated for DNA fragments
amplification based on Real-Time PCR approach. We
designed the system for E.coli DNA fragment
amplification and detection and at the same time for
E.coli quantification. The LTCC technology was used for
structure fabrication. We successfully performed PCR,
where we were able to amplify region of E.coli DNA. The
miniaturized PCR system based on the LTCC technology
might provides the possibility for faster and cheaper
E.coli detection in a different source of environmental
samples even by small laboratories or the one created in
a place of potentially E.coli contamination.
Brief Biography of the Speaker:
Malgorzata Malodobra graduated from the Wroclaw Medical
University in Poland in 2006. In the 2010 she received
the Ph.D. title at Wroclaw Medical University in
Molecular Technique Unit. From 2010 she works as a
Assistance of Professor in Molecular Technique Unit at
Wroclaw Medical University. In 2009 she performed an
internship in Joslin Diabetes Center at Harvard Medical
School, MA, USA. She is interested in the molecular
basis of metabolism syndrome, insulin resistance and
type 2 diabetes. She is also involved in many research
project performed in Molecular Techniques Unit. From
2008 she works also as a specialist in research project
dedicated to Electronic Microsystem development standing
for a single used thermalcycler for PCR in a wide range
of use, especially for medicine and environmental
hazardous factors detection. She is also performing a
diagnostic research of genetic disorders or a pathogens
detection. She is an author or co-author of eight full
text publication and an author or co-author of 13
conference abstracts in a wide field of molecular
medicine research.
