Abstract AR

في هذه الدراسة، مم اختبار تركيزات مختلفة (0.5، 1، و2%) من المتخلص الميثانولي (Usnea barbata) في المختبر كمضاد للبكتيريا ضد اثنين من البكتيريا المسبية للأمراض هما الإشريكية القولونية Escherichia coli والمكورات العنقودية الذهبي Staphylococcus aureus، وذلك باستخدام طريقة انتشار القرص.

من ناحية أخرى، تم استخدام الأريثروميسين والفلورفينيكول كيسطرة موجية بينما كانت السيطرة السلبية لزيت القطن.

أشارن النتائج بأنه لا توجد أي تأثيرات مضادة للجراثيم لمستخلص (Usnea barbata) المستخدم في هذه الدراسة.

Abstract EN

In this present study, various concentrations (0.5, 1, and 2%) aqueous methanolic extract of lichen (usnea barbata) was tested in vitro for their antibacterial activities against two pathogenic bacteria Escherichia coli and staphylococcus aureus, using the disk diffusion method.

on the other hand, erythromycin and florfenico were used as a positive control while the negative control was cotton oil.

in this study, there are no antibacterial effects of the extract of Lichen (Usnea barbata) used in this study.
