Background:
One of the major health causing problems, is contamination of drinking water sources with human pathogenic bacteria. The enteric bacteria such as Shigella, Salmonella, E. coli are the much enteric bacteria causing serious health problems. Occurrence of such these bacteria which may resist antibiotics, increase the seriousness of the problem. Objective:
Physical properties of oil, gas and connate water – porosity and permeability and the effect of diagenesis – origin, migration and accumulation of oil – oil traps and seals – drilling methods - oil exploration – formation evaluation – chemistry and grades of crude oil – reserve estimation - oil in Saudi Arabia
Bachground :Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterium responsible for several difficult-to-treat infections in humans. MRSA strains has developed, through the process of natural selection, resistance to beta-lactame antibiotics. MRSA infection are more difficult to be treated with standard types of antibiotics and thus more dangerous to human health. Objectives : To evaluate the bactericidal and antibiotic synergistic effect of silver Nanoparticles (Ag-NPs)product, against MRSA.
Synthesis of silver nanoparticles (AgNPs) has become a necessary field of applied science. Biological method for synthesis of AgNPs by Rhizopus stolonifer aqueous mycelial extract was used. The AgNPs were identified by UV–visible spectrometry, X-ray diffraction (XRD), transmission electron microscopy (TEM) and Fourier transform infrared spectrometry (FT-IR). The presence of surface plasmon band around 420 nm indicates AgNPs formation. The characteristic of the AgNPs within the face-centered cubic (fcc) structure are indicated by the peaks of the X-ray diffrac-
