Ecological Studies on Prevalence of Certain Parasites in Some Egyptian Governorates and Their Control by Using Nanoparticles

Abstract

In the present study, the prevalence of some parasites in certain water bodies found in Cairo, Giza and Qaluobyia governorates was evaluated during successive four seasons in 2014. These water bodies included River Nile, Ismailia canal, El-Sharkawia canal, Bahtem canal, El-Gizawia canal, El-Saff canal and El-Mansoureya canal.

Results of the present review described that eight parasites were identified in collected water samples (108 samples). Moreover, the most prevalent parasites were Entamoeba coli, Cryptosporidium parvum, nematode larva, Entamoeba histolytica, where they recorded 28.2%, 20.0%, 19.5% and 15.4% of total number of positive samples, respectively, while Giardia lamblia, Schistosoma haematobium eggs, Ascaris sp. eggs and Isospora sp. were 9.2%, 5.6%, 1.5% and 0.5%, respectively.

Water samples collected from Cairo and Giza governorates were more contaminated than those of Qaluobyia. However, the percentages of positive water samples for parasites were 38.5%, 37.4% and 24.1% fo
