We detected Legionella species in 111 bath water samples and 95 cooling tower water samples by using a combination of conventional plate culture, quantitative polymerase chain reaction (qPCR) and qPCR combined with ethidium monoazide treatment (EMA-qPCR) methods. In the case of bath water samples, Legionella spp. were detected in 30 samples by plate culture, in 85 samples by qPCR, and in 49 sam...

The prevention and control of legionellosis in water supply systems involves environmental comprehensive sampling. Our aim was to investigate occurrence of Legionella spp. in water supply systems in different administrative districts of Riga, and to find out if there exists a correlation between Legionella spp. positive cases and water source, type of sample, sampling point and temperature of h...

background: activity concentrations of 40k, 226ra and 228ra were measured in some sachet drinking water samples produced in nigeria. materials and methods: the measurement was done by using high-purity germanium (hpge) detector (canberra industries inc.). the measured activity concentrations for 226ra (u-series) and 228ra (thseries) were used with their ingested dose conversion factors to estim...
