Contamination of Groundwater Sources with Common Waterborne Pathogens and Heficobacter pylori in the West Bank： Case Study of Wadi AI Arroub, Tulkarem and Jericho
Contamination of Groundwater Sources with Common Waterborne Pathogens and Heficobacter pylori in the West Bank： Case Study of Wadi AI Arroub, Tulkarem and Jericho
摘要
Detection of waterborne pathogens in drinking water via rapid DNA amplification assays is an important and crucial public health method. The aim of this study is to investigate the presence of waterborne pathogens in groundwater resources in Al Arroub, Tulkarem and Jericho areas using direct PCR （polymerase chain reaction） analysis. Forty-six groundwater samples were collected. The total DNA was extracted from each sample and subjected to PCR analysis directed to specific genes of enteric bacteria, β-lactamases producing bacteria, L. pneumophila （Legionella pneumophila） and H. pylori （Helicobacter pylori）. Enteric bacteria were detected with high frequency in Palestinian water sources followed by 13% occurrence of β-lactamases producing bacteria, 9% of H. pylori and 4% of L. pneumophila. The study shows that shallow groundwater wells and water taped from karstic aquifer is potential for contamination and could not be reliable sources of potable water.
