Failure to detect Helicobacter pylori in tap water sources in Al- Najaf and Babylon provinces by using PCR based on ureB gene.

Abstract

500) sample collected from the study area, divided into (250) from the province of Najaf and (250) from the province of Babylon, and distributed by two models for each sample. I use the first model to estimate the level of free chloride , pH, dissolved substances college and temperature, while the use the other form of the same sample to check for the presence of bacteria in tap water in a PCR study showed a large disparity in the levels of pH, free chlorine, dissolved substances college and the temperature you two provinces were the highest percentages for the Abbasia in Najaf Ashraf and the least in the Alhaidariya in the same province study also demonstrated the existence of significant correlation between the level of free chloride each of the temperature, dissolved substances College and the pH while the highest in the region of Mahaweel in the province of Babylon, and the least in Jordan in the same area of the province and which should be mentioned to him the failure mode (PCR) in detecting the presence of Helicobacter pylori bacteria in tap water in the both provinces . H.pylori :-Helicobacter pylori . T D S :-Total dissolved solids . PCR :-Polymerase chain reaction .
