描述
6-hydroxynicotinic acid (6-OHNA) is exploited in the use of NMR spectroscopy or gas chromatography--mass spectrometry for the diagnosis of Pseudomonas aeruginosa in urinary tract infection. Among the common bacteria causing urinary infection, only P. aeruginosa produces 6-hydroxynicotinic acid from nicotinic acid. Pseudomonas aeruginosa infection has been reported to be the third leading cause of urinary infection, accounting for 11% of such infections, the first and second being Escherichia coli and Klebsiella pneumonia, respectively. Analyses of the NMR spectra of the bacterial media with variable cell count of P. aeruginosa, shows that the intensity of the signals of the 6-hydroxynicotinic acid increases with increasing number of bacterial cells.
