[ 6 ] - شناسایی سروتایپ های سالمونلا در طغیان های غذایی با استفاده از سکانس ناحیه ی ITS ژن 16S-23S rRNA
زمینه و هدف: بیماری های منتقله از غذا یکی از مشکلات جامعه ی امروزی است. در بسیاری نقاط جهان˓ بررسی های اپیدمیولوژی نشان داده است که عفونت های ناشی از سرووارهای سالمونلا افزایش یافته است. بدین منظور شناسایی سویه های سالمونلا در سطح سرووار از اهمیت خاصی برخوردار است. ظهور سویه های مقاوم در این سرووارها به یک نگرانی جهانی تبدیل شده است، بنابراین آگاهی از الگوی مقاومتی در سالمونلاها می تواند به در...
[ 7 ] - بررسی خاصیت آنتی باکتریال کوکتل باکتریوفاژ نسبت به برخی سروتیپ های باکتری سالمونلا انتریکا (انتریتیدیس، تیفی موریوم، اینفنتیس) در مقایسه با سیپروفلوکساسین درشرایط in vitro برای اولین بار در ایران
Background: Salmonellosis is a gastroenteritis caused by the infection with different serotypes of Salmonella. Salmonella enterica is an enterica subtype, enteritidis, typhimurium, and infantis are the most important factors of gastroenteritis in humans. In recent years, increasingly commonly used antibiotics and treatments are resistant. The main purpose of this study was to compare the antiba...
[ 8 ] - Antimicrobial resistance pattern of citrobacter species isolated from food outbreaks
Background: Foodborne diseases and resistance to antimicrobial agents are two of the world's most widespread global issues. Also, the excessive use of antibiotics has led to the resistance of bacteria belonging to the Enterobacteriaceae family to antibiotics, especially in carbapenems. Citrobacter is an opportunistic bacterium that is resistant to antibiotics in the emerging bacteria and has ...
[ 9 ] - Prevalence of Staphylococcus Aureus Isolated from Hamburger Samples in Tehran and their Antibiotic Susceptibility
Introduction:Staphylococcal food poisoning is one of the most common food-borne diseases. The antibiotic resistance of Staphylococcus aureus has been reported globally. Today, strains of Staphylococcus aureus in food have become a problem in clinical infections and are considerde as a serious public health concern. Methods: A total of 100 samples were tested in the laboratory; including 75 han...
[ 10 ] - Effect of Bacteriocin Produced by Lactobacillus casei with Probiotic Potential Isolated from Milk on the Ability of Biofilm Production by Streptococcus salivarius Obtained from Dental Plaque
Background and purpose: Dental plaque is a biofilm that is formed on the surface of the tooth. Carious lesions are caused by inappropriate ecological changes in microbial flora of the plaque biofilm. In this study, the effect of Lactobacillus casei bacteriocin, isolated from dairy products, was investigated on Streptococcus salivarius biofilm formation. Materials and methods: In this experimen...
[ 11 ] - Evaluation of Specific Bacteriophage Against Salmonella infantis and Its Antibacterial Effects Compared to Ciprofloxacin in In Vitro Conditions
Background and Objective: Phage therapy could be used as an alternative method to antibiotic treatments. The purpose of this study was to evaluate the antibacterial activities of isolated lytic bacteriophage against ciprofloxacin-resistant strain of Salmonella infanits in vitro conditions. Materials and Methods: The standard strain of Salmonella infantis and its specific bacteriophage was iso...
[ 12 ] - Evaluation of Probiotic Properties of Lactobacilli in Breast Milk and Their Inhibitory Effect on Pathogenic Bacteria of the Gastrointestinal Tracts
Background and Objective: Breast milk contains nutrients such as carbohydrates, essential fatty acids, proteins, vitamins, minerals, and a source of communal bacteria with probiotic potential that is very effective in the prevention and treatment of neonatal infections.
