Abstract

This study included four aspects:


Collection of 200 samples of patients with four different pathogenic cases: Burns infections, Wound infections, Urinary Tract Infections & diarrhea , for period ( September 2016 – March2017) . 403 bacterial isolates were got. Gram negative bacteria represented  329  isolates (48.9%  E.coli ). The percentages of E.coli  isolates  are different depending on isolation sources and the Urinary Tract Infections have the highest (72.2%).


Antibiotic Susceptibility test was performed for 10  antibiotics, all isolates of  E.coli  showed perfect resistance against  Penicillins & Cephalosporins while they have high sensitivity to Nitrofurantion . The other  6 antibiotics have different effects depending on the isolation sources.


Natural Honey has potential high ability for  E.coli  growth inhibiting without any influence with isolation sources , MIC of Ntural Honey is  15%.


The inhibition activity was tested for Ethanol (95%) Extracts of four Medicinal plants : Allium sativum , Paganum harmala , Nigella sativum & Myrtus communs . All of these extracts have high inhibitory effect on  E.coli  isolates without any influence of the isolation sources. Allium sativum extract has the highest effect with inhibition zone diameters (20.1-32.0) mm.
