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.
