The study was conducted in the laboratories of the
department of Biology - Faculty of Science, which
cope with the effect of different concentrations of
silver nanoparticles in inhibiting the growth of
pathogenic bacteria species isolated from
thechildren with diarrhea aged (2-4) years. The
results of this study proved the efficiency in
inhibiting growth of E. coli by silver nanoparticles
where diameters of the inhibition zone (12.21,
16.24, 23.11, 26.38 mm) at concentrations 25, 50,
75and 100 (µl)respectively, the inhibiting efficacy
of the silver nanoparticles in inhibition of the
growth of Proteus mirabilis(10.76,13.32,17.44,
20,33 mm) , the inhibiting ability on the Shigella
flexnerigrowth (8.32, 10.32, 11.07, 13.58) mmat
the same concentrations , the inhibiting efficacy of
the silver nanoparticles in inhibition of the growth
of Staphylococcus aureus wherediameters of the
inhibition zone (11.72, 13.42, 15.31, 17,12 mm) at
the same concentration , also The results exposed
that silver nanoparticles were able to inhibit
Enterobacter cloacae growth wherediameters of the
inhibition zone (10.31, 12.43, 14.71, 15.68 mm) at
concentrations 25, 50, 75and 100 (µl)respectively
