Comparative bacteriological study of different sites on Tigris and Uphrities rivers


study was established to determine and indicate some biological analysis viz; Aerobic bacteria total count (Abtc), Total coli form (Tc), Fecal coli form(Fc), Fecal streptococci(Fs), Pseudomonas aeruginosa and Salmonella Spp for river Tigris and Uphrities rivers water. In addition water chemical measurements have been carried out, viz;total dissolved solid (TDS). Samples were taken from study sites. Tow groups of samples have been taken from each site during the the hot season.The results indicated count that there was an increasing in the investigated bacteria in raw water . The results also showed that there was almost equal in total coli form, fecal streptococci and fecal coli form in the study sites in the hot season .The numbers of pseudomonas aeruginosa bacteria was higher in hot season, However the correlation coefficient between total dissolved solid (TDS) were highly significant negative. The increase of T.D.S decrease the bacteria in the investigated site.
