A total of 480 samples of locally produced processed meats, including chicken franks, chicken bologna, and bacon from brands A and B, was collected from 8 supermarkets across the island of Trinidad over a 1-year period and subjected to a range of microbiological analyses. The results showed that 54.2, 0.4, and 1.7% of the samples exceeded recommended limits for aerobic bacteria, Escherichia col...
The influences of cell-free solutions (CFSs) of lactic acid bacteria (LAB) on cadaverine and other biogenic amines production by Listeria monocytogenes and Staphylococcus aureus were investigated in lysine decarboxylase broth (LDB) using HPLC. Cell free solutions were prepared from Lactococcus lactis subsp. lactis, Leuconostoc mesenteroides subsp. cremoris, Pediococcus acidilactici and Streptoc...
چکیده زمینه و اهداف: گیاه حرا با نام علمی Avicennia marina (Forssk.) Vierh رایج ترین گونه این گیاهان در جنگلهای مانگرو ایران است. با توجه به وجود ترکیبات بیولوژیکی فعال و استفاده سنتی از برگ آن جهت درمان آبله و زخمها، به نظر میرسد این گیاه دارای اثرات ضد میکروبی قابل ملاحظهای باشد. هدف از این پژوهش ارزیابی اثر ضد میکروبی غلظت های مختلف برگ گیاه حرا بر سه میکروارگانیسم شاخص عامل عفونت و مسمو...
BACKGROUND Since ancient times, various infectious diseases have been treated using herbal drugs. Today, efforts regarding the discovery of the effectual components of plants possessing antimicrobial properties are advanced. Herbal essential oils are widely used for treatment of various diseases, and they play an important role in health care considerations. METHODS The antibacterial activity...
Melastoma malabathricum Linn. is a shrub that comes with beautiful pink or purple flowers and has berries-like fruits rich in anthocyanins. This study was carried out with the aim to evaluate the inhibitory activities of different concentrations of the M. malabathricum Linn. flower and fruit crude extracts against Listeria monocytogenes IMR L55, Staphylococcus aureus IMR S244, Escherichia coli ...
In this study, Suillus spp. after determining the dry matter and protein amounts of mushroom, antioxidant antimicrobial activities ethanolic extracts were investigated. Free radical scavenging activity was determined by DPPH method phenolic content HPLC. Antimicrobial against microorganisms that Staphylococcus aureus, Escherichia coli, Salmonella Typhimurium, Listeria monocytogenes Pseudomonas ...
Mobile genetic elements (MGEs) encoding virulence and resistance genes are widespread in bacterial pathogens, but it has remained unclear how they occasionally jump to new host species. Staphylococcus aureus clones exchange MGEs such as S. aureus pathogenicity islands (SaPIs) with high frequency via helper phages. Here we report that the S. aureus ST395 lineage is refractory to horizontal gene ...
Background & Aim: Lactic cheese is traditionally produced from raw milk in some provinces of Iran. Therefore, presence of pathogenic bacteria in these cheeses can be dangerous to human health. The aim of this study was to evaluate the contamination rate of local lactic cheeses produced in Gorgan with Escherichia coli, Staphylococcus aureus and Listeria monocytogenes. Methods: Cheese samples we...
although some venoms and their isolated compounds have been shown to have antibacterial properties, most have not been investigated for such activity. echis carinatus is one of the most venomous snakes in the world and has an effective haematotoxic venom that destroys endothelial cells and causes haemorrhagia. in this study, the antibacterial activity of iranian snake echis carinatus venom agai...
Background: Staphylococcus aureus, Salmonella enterica, Escherichia Coli (E. Coli) and Listeria monocytogenes are considered as important foodborne pathogens. Pistachia atlantica sub sp. Kurdica, called wild pistachio, has been known as an antimicrobial compound. The aim of this study was to determine the antimicrobial activity and chemical composition of this essential oil (EO) on some of food...
