Market Need

Legionella pneumophila is a water-borne bacterial pathogen that causes Legionnaire鈥檚 disease in humans. During an outbreak, quickly analyzing all of the potential water sources is essential to reduce the spread of disease. The methods currently available, however, require expert skills and are time intensive. Not only does this delay intervention during an outbreak, but also makes routine checks more difficult.

Technology Summary

With the help of the Systematic Evolution of Ligands by Exponential enrichment process, two aptamers were produced that bound selectively and with a high sensitivity to Legionella. Because they are short oligonucleotide sequences and can bind to specific molecules, aptamers are considered promising biorecognition molecules. During conformational tests, their binding specificity was confirmed by flow cytometry and fluorescence microscopy. With a high level of specificity for Legionella, these aptamers could improve detection efficiency and allow routine monitoring of at-risk water reservoirs.
