Popis: In order to investigate the ability of Fluorocult-supplemented TSC agar (TSCF (Fluorocult supplemented TSC-agar): prepared from Tryptose Sulfite Cycloserine Agar Base (Merck), D-cycloserine (Fluka Chemika, USA), and fluorocult TSC-Agar supplement (Merck)) for detecting spores of Clostridium perfringens in water, we analyzed groundwater samples, pretreated by heating to 80 degrees C/5 min, using this fluorogenic medium together with five other media: mCP agar (Panreac; Cultimed), TSC agar (Merck, Germany), TSN agar (Merck), and SPS agar (BBL, USA) by the membrane filtration technique, and Wilson-Blair agar (WB) following the still-in-force Spanish official method. Variance analysis of the data obtained shows statistically significant differences in the counts obtained between media employed in this work. The C. perfringens spore counts on mCP agar were significantly lower (P
