Investigation of parasitic contamination in Kufa river water Al-Najaf province

الملخص EN

This study was carried out to estimate the prevalence and potential for human infectivity of parasites in Kufa river.

Samples were collected from three stations across Kufa river from July (2012) to February (2013) at approximately half monthly intervals.

The first two stations represent the location of the most frequent sources for water pollution : Station where sewage and drainage water have discharged and station of slaughterhouse where the animal's residues shed to water.

The third station was the place where Najaf city supply with water Liquefaction of water.

There was a trend to higher concentration and more frequent incidence of parasites in the spring and fall, but positive samples were found in all seasons.

Distribution of parasitic contamination in station one, determining the incidence and prevalence of human enteric protozoan parasites such as Giardia lamblia, Cryptosporidium parvum, Entamoeba coli, Entamoeba histolytica, Balantidium coli, in different parasitic contaminated samples will provide baseline data against the risk factors associated with waterborne pathogenic protozoa transmission.

In the second station worms are the most common distributed parasites which transmitted via water to humans, such as Ascaris lumbricoides, Ancylostoma duodenale, Trichuris trichura, and Taenia saginata, and Fasiola hepatica while the third station were also positive but for protozoa (Giardia lamblia, Entamoeba coli, Entamoeba histolytica and Cryptosporidum parvum).

These are water transmitted protozoa.
