[ 1 ] - Identification of Shigella species and their antibiotic resistance patterns from dysenteric patients in Baradaran Rezaei hospital of Damghan, Northeast of Iran
Shigella is a major cause of dysentery across the world. Appropriate antibiotic treatment of shigellosis depends on resistance patterns. The present study was conducted to identify Shigella species and their antibiotic resistance patterns among dysenteric patients in Rezaei Hospital of Damghan. Isolation of Shigella species was conducted by specific culture medium and biochemical tests. The Shi...
[ 2 ] - بررسی توان تثبیت نیتروژن در اندوفیت های باکتریایی و قارچی جدا شده از گرهک‌های ریشه درختان توسکا و سنجد
نیتروژن یکی از مهمترین عناصر مورد نیاز گیاهان می باشد، اما گیاهان قادر به احیای نیتروژن اتمسفر به آمونیاک و استفاده از آن به طور مستقیم برای رشد نیستند. میکروارگانیسم های تثبیت کننده نیتروژن با فرآیند تثبیت نیتروژن، نیتروژن مورد نیاز را به صورت قابل مصرف در اختیار گیاه قرار میدهند و نقش مهمی در حاصلخیزی خاک دارند. هدف از این مطالعه بررسی تثبیت نیتروژن در میکروارگانیسم های اندوفیت جدا شده از...
[ 3 ] - Isolation and molecular identification of carotenoid-producing bacteria
The production of pigments from bacteria is significant due to the low cost, high yield and ease of extract compared with other sources. Carotenoids are one of the most important pigments with antioxidant properties which are the precursor of vitamin A synthesis and have antibody overproduction ability, anti-tumor activity and inhibitory effect on the cardiovascular disease. The present study a...
[ 4 ] - Phenotypic Investigation of Biofilm Formation and the Prevalence of icaA and icaD Genes in Staphylococcus epidermidis Isolates
Background and Aims: The most important factor for pathogenicity of Staphylococcus epidermidis is the ability to produce biofilm. Identification of biofilm-forming strains using an appropriate method and recognizing the mechanisms of biofilm formation can help understand the proper use of artificial medical equipment and prevent increased drugs resistance . The aim of this study was to 1) evalu...
