BackgroundThe development of antibiotic resistant bacteria stems from a number of factors, including inappropriate use of antibiotics in human and animal health and their prolonged use as growth promoters at sub-clinical doses in poultry and livestock production. We were interested in investigating plants that could be useful in protecting humans or animals against diarrhoea. We decided to work on extracts of nine plant species with good activity against Escherichia coli based on earlier work… 
In Vitro Antibacterial Activities of Various Ethanolic Medicinal Plant Extracts Against Some Human Pathogenic Bacteria
Assessment of the antibacterial effect of five medicinal plant prevailed in Kurdistan region found that the ethanol plant extracts had potential antibacterial activities, however, further studies are required to identify the active compounds which could be used for the preparation of new antimicrobial agents and control the bacterial infectious diseases.
