Holy water--a risk factor for hospital-acquired infection.

A case of hospital-acquired infection due to Acinetobacter baumanii in a burns patient after exposure to holy water is described. In order to assess the infection risk, 13 samples of holy water were cultured for bacteria, (including legionellae) and yeasts. Viable bacterial counts ranged from 1 center dot 3 x 10(3)-3 center dot 8 x 10(8) cfu/L (mean 3 center dot 1 x 10(7) cfu/L). A wide range of bacterial species was isolated including Pseudomonas aeruginosa, Enterobacter spp. Escherichia coli and Aeromonas hydrophila. Candida spp. were isolated from two samples, but legionellae from none. Holy water would, therefore, seem to be a potential risk factor for hospital-acquired infection.
