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.
