Polymerase chain reaction and nested-PCR approaches for detecting Cryptosporidium in water catchments of water treatment plants in Curitiba, State of Paraná, Brazil
SHORT COMMUNICATION - Occurrence of Cryptosporidial Oocysts and Giardia  Cysts in Bottled Mineral Water Commercialized in the City of Campinas, State of São Paulo, Brazil
The consumption of bottled mineral water has significantly increased in
Brazil so that it is in the interest of public health to determine the
parasitological and microbiological status of some brands of Brazilian
mineral water available in the town of Campinas, São Paulo,
Brazil. For this purpose, detection of protozoa by direct
immunofluorescence technique and microbiological parameters were
determined for each specimen after membrane filtration. Giardia Â
cysts were not present while cryptosporidial oocysts were detected in
two samples. The counts of protozoa varied from 0.2 to 0.5 oocysts/l.
The detected level of Pseudomonas aeruginosa and heterotrophic bacteria
reflected the level of organic enrichment of the water
