Background and purpose: Staphylococcus aureus is an important nosocomial pathogen which causes some diseases such as endocarditis, osteomyelitis, pneumonia, toxic shock syndrome, and food poisoning. The excessive and inappropriate use of antibiotics in the treatment of these diseases causes resistance to many antibiotics. Lysostaphin is an effective agent in the treatment of staphylococcal infe...
Background: The radiation emitted from electromagnetic fields (EMF) can cause biological effects on prokaryotic and eukaryotic cells, including non-thermal effects. Objective: The present study evaluated the non-thermal effects of wireless fidelity (Wi-Fi) operating at 2.4 GHz part of non-ionizing EMF on different pathogenic bacterial strains (Escherichia coli 0157H7, Staphylococcus aureu...
Background and objectives: Despite the vast production of new antibiotics in the last three decades, resistance to these drugs by microorganisms has increased and essential oils (EOs) have been recognized to possess antimicrobial properties. Methods: In the present study, EOs obtained from aerial parts of Thymus vulgaris L., Lavandula angustifolia Mill., Rosmarinus offici...
background: many efforts have been done to find effective agents against resistant pathogens. cuminum cyminum l. (cumin) is an aromatic plant within the apiaceae family. it has a variety of purposes and demonstrates antimicrobial and antioxidant properties. this study evaluated the activity of c. cyminum extract and essential oil against bacterial isolates which cause urinary tract infection, i...
Background and Objective: This study aimed to determine the antibacterial activity of either zinc oxide or copper oxide nanoparticles alone or combined against Gram-positive and Gram-negative bacteria. Materials and Methods: In this experimental study Escherichia coli (E. coli ATCC 25922), Staphylococcus aureus (S.aureus ATCC 25923), Pesudomonas aueroginosa (P. aueroginosa ATCC 27853) and Staph...
Staphylococcus aureus, as a foodborne pathogen causing significant harm worldwide, was studied to assess the effectiveness of probiotic strains Lactobacillus casei, plantarum, and Bifidobacterium bifidum individually collectively (as consortia) in controlling its growth. The growth patterns S. aureus were observed when co-cultured with each strain consortium all three over 72 hours. Additionall...
Regarding increasing rate of drug resistance among microbial pathogens, a global search to find new antimicrobial agents from natural compounds with fewer side effects has been considered by many researchers worldwide. Bioactive compounds with good antimicrobial activity have been isolated from different algae and cyanobacteria. The current study was performed to determine antimicrobial potenti...
nepeta depauperata belongs to the lamiaceae family and is one the persian endemic plants which has not been investigated biologically. in the present paper we had focused on the assessment of the antibacterial and antifungal activities of the total methanolic extract and different sub-fraction of the flowering aerial parts of it. the antibacterial and antifungal activities were investigated by ...
abstract the purpose of this study is twofold: on the one hand, it is intended to see what kind of noticing-the –gap activity (teacher generated vs. learner generated) is more efficient in teaching l2 grammar in classroom language learning. on the other hand, it is an attempt to determine which approach of the noticing-the-gap- activity is more effective in the long- term retention of grammar...
Gallium is a trivalent semi-metallic element that has shown antimicrobial activity against several important human pathogens. This antimicrobial activity is likely related to its substitution in important iron-dependent pathways of bacteria. The genus Staphylococcus, which includes human and animal pathogens that cause significant morbidity and mortality, requires iron for growth and colonizati...
