ABSTRACT
The occurrence of Cryptosporidium spp. in superficial waters at the Metropolitan Region of Recife, PE, was studied. Raw and treated water were analyzed by filtration of the samples on a membrane (47mm, 3µm) under negative pressure, by the direct immunofluorescence assay (IFA), and by the 4'6'-diamidino-2-phenylindole (DAPI) method. The samples were analyzed during drought (September to February) and raining (March to August) seasons. Oocysts were not found in treated water. Cryptosporidium spp. oocysts were found in non-treated water by IFA/DAPI technique in 40% (2/5) of the locations and in 5% (3/60) of the samples investigated, with the number varying from 16 oocysts/l to 40/l, in dry and raining seasons, respectively. This is the first report of Cryptosporidium spp. in surface water in the state of Pernambuco, Northeast of Brazil.
