مسمومیت های غذایی ناشی از باکتری listeria monocytogenes منجر به مرگ و میر 30 % از افراد مبتلا می شود. با توجه به احتمال بالای آلودگی ماهیان پرورشی به باکتری l. monocytogenes، هدف تحقیق حاضر، بررسی استفاده از اسانس آویشن و باکتریوسین نایسین به تنهایی و توأم با یکدیگر جهت مهار رشد باکتری لیستریا مونوسایتوژنز در گوشت چرخ شده ماهی فیتوفاگ بود. نتایج حاصل از بررسی اثر بازدارندگی اسانس آویشن بر باکتر...
the objective of this study was to isolation and characterization of listeria species and determines listeria monocytogenes serotypes in fresh fish, shrimp, crab and lobster in isfahan and shahrekord, iran. from september 2010 to april 2011, a total of 300 samples of fresh fish, shrimp, crab and lobster were obtained from randomly selected retail stores in isfahan and shahrekord, iran. the samp...
conclusions shedding of l. monocytogenes in different animal species, and different samples are different. due to antibiotic resistance, especially in l. monocytogenes, veterinarians should pay more attention to prescribe antibiotics. we recommend using the real-time pcr for safe, sensitive, and rapid detection of l. monocytogenes in clinical samples, and using the disk diffusion methods to pre...
Background & Objectives: Listeria bacterium resists to the sludge digestion conditions and Listeria monocytogenes is the most important of them. Sludge produced in the north Isfahan wastewater treatment plant is stabilized by anaerobic digesters and is used for fertilizing agricultural lands after drying in the sludge drying beds. Based on the importance of the subject, the objective of this st...
Background and Objectives: Listeria monocytogenes are known as an emerged foodborne pathogen and considered as a severe health risk. In the present study, prevalence and antibiotic resistance of L. monocytogenes isolated from ready-to-eat meat products in Iran were assessed. Materials and Methods: A total of 200 ready-to-eat meat products, including chicken meat (wing, breast, and leg), lamb a...
Background & Objective: Listeria monocytogenes has already established as an important food born pathogen which induce listeriosis in human. Use of bacteriocins to provide food safety has been increased dramatically. Nisin has a wide spectrum inhibitory effect than the other bacteriocins and inhibits food-borne pathogens such as L. monocytogenes and many other Gram-positive spoilage microorg...
endometritis as a risk factor for cystic ovarian disease, anoestrus and other reproductive disorder, is characterized by impact of dairy production performance and causes serious economic losses. listeria monocytogenes can cause endometritis. considering the importance of what mentioned present study was conducted to detection of l. monocytogenes in bovine endometritis from shahrekord, iran. al...
Background & Aims: The ubiquitous nature of Listeria monocytogenes and its ability to grow at refrigerated temperature makes L. monocytogenes a serious threat to the safety of ready-to-eat (RTE) meat products. Lactic acid bacteria (LAB) have been found to be effective in inhibiting L. monocytogenes in food products such as fresh and cooked meats. Prebiotics exist in many foodstuffs such as...
conclusions based on our study, plca and hlya played a key role in the virulence determination of l. monocytogenes. data analysis also showed that l. monocytogenes could be a causative agent of abortion in pregnant women. results out of 96 samples, 16 isolates of l. monocytogenes by pcr (plca and hlya) and four isolates by culture were identified. there was a significant difference between pcr ...
