Introduction: This study was intended to determine the presence and distribution of Listeria monocytogenes in various meat and dairy products from Qazvin Province by culture followed by biochemical and morphological assays. The identity of the isolates was further obtained by amplification of prfA gene in bacteria isolates. This gene is a transcriptional activator of virulence gene ex...

listeria monocytogenes can cause serious infection and recently, relapse of listeriosis has been reported in leukemia and colorectal cancer, and the patients with klebsiella pneumoniae are at increased risk of colorectal cancer. translation initiation codon recognition is basically mediated by shine-dalgarno (sd) and the anti-sd sequences at the small ribosomal rna (ssu rrna). in this research,...

the purpose of this preliminary study was to determine the prevalence of raw milk contamination with listeria monocytogenes. in this study, 100 bulk tank milk samples were collected randomly and delivered to pegah pasteurization factory in mashhad.for isolation and identification of l. monocytogenes, the samples were first enriched using cold enrichment method in listeriaenrichment broth, follo...

conclusions probable mechanism of suppression of energy generation is suppression of the rise in glucose. results listeria monocytogenes was controlled using 2 mm of osthole. treatment of l. monocytogenes by 2 mm osthole had no effect on the atp level. objectives osthole has antibacterial properties, but its mechanisms of action is still unknown. materials and methods two millimoles of osthole ...

discussion l. monocytogenes can cause progressive and rapidly fatal infections in the vulnerable persons, with multisystem involvement. since this bacterium is not susceptible to cephalosporines, it will be better to consider effective antimicrobials in the treatment of the possible cases. case presentation a 70-years-old patient with chronic renal failure was admitted to the infectious disease...

in this study, the effects of various concentrations of nacl and kcl and partial replacement of nacl withkcl on the growth characteristics of l. monocytogenes were evaluated. it was found that l. monocytogenescan grow in the presence of 1-9% nacl and 1-11% kcl. the higher the concentration of salt used, the longerthe lag phase induced. in addition, it was observed that l. monocytogenes tolerate...
