Abstract
Background: An alarming rise in bacterial strains resistant to existing antimicrobial agents requires a renewed effort to seek agents
effective against pathogenic bacteria resistant to antimicrobials. The new antimicrobial agents are will overcome this problem.
Objective: This study aimed to study the in vitro antimicrobial activity of different concentrations of Honey, petroleum ether extracts
of medicinal plant Nigella sativa (seeds), and the mixture using the cup-plate agar diffusion method.
Materials and Methods: This cross-sectional observational study was carried out among One hundred samples were collected from
urine, wound, ear, and eye swab, 95/100 (95%) showed bacterial growth, from which six types of pathogenic bacteria at Shendi city
hospitals during March to June 2018.
Results: Of the total 95 clinical and standard specimens were confirmed as Staphylococcus aureus 20 (21%), Escherichia coli 20
(21%), Pseudomonas aeruginosa 15 (16%), and Klebsiella pneumoneae 30 (31%). In addition to Candida albicans 10 (11%). These
results showed the activity of antimicrobial Petroleum ether extract of the Nigella sativa, and honey pronounced dose-dependent on
standard strains and clinical isolates, while methanolic extract of Nigella sativa explained no activity.
Conclusion: The activity of Nigella sativa, honey, and the mixture exhibited high antimicrobial activity against all types of tested or ganisms both clinical and standard organisms. Therefore Nigella sativa, honey, and the mixture can be regarded as a broad-spectrum
antimicrobial agent.
