The Impact of Some physical and Chemical Properties on Numbers of Salmonella sp and E. coli Bacteria in Diwaniya River

Abstract

This research has been conducted to determine the effect of environmental conditions (such as Temperature - Hardness - Salts - Turbidity - acidic - Sulfates - Dissolved oxygen - Calcium - Magnesium - TDS) on the number of bacteria Escherichia coli, Salmonella SP in Diwaniya River water. Results have shown that the PH was neutral PH values tend to basal light during the month of February and also showed dissolved oxygen few high-definition because microbiology amounts of dissolved oxygen consumption for the purpose of bio-activity and analysis of organic materials in the river water. As it turns out that Diwaniya River water hardness is very high during the study. As for the conduct bacteriological tests results have shown that the bacteria E.coli bacteria compete Salmonella sp for survival observed that the environmental conditions they are in favor of the bacteria E. coli in terms of increasing their numbers during the study season, the number of E. coli bacteria have ranged from 12000 mg / L in the second station and 700 mg / L in the first station during the month of February As for the bacteria Salmonella SP ranged numbers between 600 mg / L in the third station during month February and 0 mg / L in the first station during the month of march.
