Occurrence of cryptosporidium spp., giardia spp. and other pathogenic intestinal parasites in the beberibe river in the State Of Pernambuco, Brazil

Abstract

Introduction: Transmission of pathogenic protozoa and helminths by water is a serious public health problem. In this study, we analyzed the presence of these organisms in the Beberibe River in Pernambuco, Brazil. Methods: Parasite analysis was performed using the Hoffman, Pons, & Janer method followed by centrifugation and preparation of slides by staining with acetic acid and Lugol’s solution. Protozoan oocysts were isolated by the modifi ed Ziehl Neelsen method. Results: Cryptosporidium spp., Giardia spp. and other parasites were found in the Beberibe River. Conclusions: Sanitation companies must assess pathogenic intestinal parasites in water basins providing public water and subsequently develop improved treatment systems for removal of such parasites.
