Abstract Water quality assessment of River Nile, treated tap water and groundwater has been studied in the Upper Egypt region (Sohag governorate) between April 2011 and March 2012 to identify the relationship between the physicochemical parameters and microbiological characteristics. One hundred and twenty water samples were collected during hot and cold seasons along the area extending from Tima to Dar-Elsalam cities along Sohag governorate, Egypt. Results indicated that the physicochemical parameters in all samples increase significantly in the hot season than cold season. In addition, the bacteriological assessment for River Nile water and groundwater samples indicated that most of locations were polluted with faecal coliform and pathogenic bacteria which were identified as E. coli, Salmonella spp., Pseudomonas aeruginosa and Shigella spp. Treated tap water samples were free from the pathogenic microorganisms. Antibiotic susceptibility was carried out on all isolated strains which had shown different resistance between the strains to the different antibiotics. Plasmid was isolated and detected in most strains especially in Salmonella spp and shigella spp which were contained a large plasmids. Also, strains which were contained plasmids were mostly resistant to antibiotics. MRSAPCR was carried out on all strains and the obtained results proved that all strains did not contain methicillin gene which was present in Staphylococcus aureus. |
