The series of scientific articles, based on the microbiological research beneficing PMEU methods, continues. The new model of PMEU, "Scentrion", measures the gaseous metabolites, derived from the microbial activity in the sample syringes, and gives therefore the fastest indication of very low contamination levels in only 2..3 hours. PMEU Scentrion is already applied in a Finnish hospital laboratory. It is one of the new PMEU innovations, presented in a short R&D period in 2009 (another is PMEU "Spectrion" where the detection of the microbial growth bases on automatic turbidity measurement - more about it in future posts of this blog).
A short notification of this article follows below (to have more detailled view into the method and results derived with it, please refer the original article, published in June 2009 by Pathophysiology):
"E. Hakalehto, J. Pesola, A. Heitto, B. Bhanj Deo, K. Rissanen, U. Sankilampi, T. Humppi, H. Paakkanen.
Fast Detection of Bacterial Growth by using Portable Microbe Enrichment Unit (PMEU) and ChemPro100i® Gas Sensor.
Pathophysiology 16:1 (2009) 57-62.
PMEU Scentrion gives results in a few hours from the cultures, starting from only single cells per ml to a few hundreds of cells per ml. It is therefore a clear improvement to even PCR methods, which normally require an overnight pre-enrichment to be practically sensitive enough."
