Journal Title: IOSR Journal of Pharmacy (IOSRPHR) - Year 2015, Vol 5, Issue 4
Abstract
In Pakistan there is not a good awareness about water borne diseases. It is just due to lack of knowledge and infrastructure and it is not a hidden thing that in Pakistan water borne diseases are not different from world. In this study determination of coliforms specially E.coli, P.aeruginosa, Salmonella and H. pylori were isolated and identified by using 100 ml of drinking water sample from common sources. WHO recommendation tells us that any 100 ml water sample used for deinking must not contain any coliforms in it. In this study a total of 90 samples were collected from 3 different cities of Hazara Division (Mansehra, Abbottabad and Haripur). To find out pathogenic bacteria culturing technique was used followed by staining for identification of bacterial specie. In Mansehra 15 samples (16.66%) were found pathogenic, 18 samples (20%) from Abbottabad and 16 samples (17.77%) from Haripur respectively. Four Different bacterial species were found i-e E.coli, P. aeruginosa, Salmonella and H. pylori. Ecoli was mostly isolated specie that was identified in 24 samples (26.66%) followed by P. aeruginosa 11 samples (12.22%), H. pylori 8 samples (8.88%) and Salmonella 6 samples (6.66%). This study concludes that disinfection of water should be implemented to reduce water borne diseases, water supplying departments have to follow WHO standards for better public health and to control disease outbreak by coliforms
