We have used Southern hybridization analysis to characterize the extent of fim homology in recognized type 1 fimbriae mutants of Escherichia coli K12, including strains HB101, P678-54, and VL584. We have found extensive homology in strain HB101, and confirm that P678-54 lacks the majority of fim DNA. Strain VL584 contains a deletion of the entire fim region. We have used a new allelic exchange ...
چکیده زمینه و هدف: مورد گیاهی است که خاصیت ضد میکروبی داشته، از رشد باکتری ها ممانعت کرده و مرگ بسیاری از پاتوژن ها را باعث می شود. با توجه به مشخص بودن مکانیسم اثر بسیاری از داروهای ضدمیکروبی ، هنوز مکانی س م اثر ضدمیکروبی این گیاه به درستی مشخص نشده است. در این تحقیق مکانی س م اثر ضدمیکروبی عصاره متانولی مورد ، بر روی باکتری e .coli hb101 مطالعه و بررسی شده است. مواد و روش ها: در این مطالعه آ...

An alcohol dehydrogenase (ADH) gene from Clostridium acetobutylicum was cloned on a recombinant plasmid, pCADH100. Escherichia coli HB101, and an allyl alcohol-resistant mutant, HB101-adh1, containing this plasmid were unable to grow aerobically or anaerobically on agar media containing sublethal concentrations of allyl alcohol. E. coli HB101 and HB101-adh1 transformed with the plasmid pCADH100...
Escherichia coli RNase E is an essential enzyme that forms multicomponent ribonucleolytic complexes known as "RNA degradosomes." These complexes consist of four major components: RNase E, PNPase, RhlB RNA helicase, and enolase. However, the role of enolase in the RNase E/degradosome is not understood. Here, we report that presence of enolase in the RNase E/degradosome under anaerobic conditions...
Recent reports have indicated that small RNAs have key roles in the response of the E.coli to stress and also in the regulating of virulence factors. It seems that some small non-coding RNAs are involved in multidrug resistance. Previous studies have indicated that rprA can increase the tolerance to Kanamycin in RcsB-deficient Escherichia coli K-12 following osmotic shock. The current study aim...
Pyrolysis mass spectrometry (PyMS) and multivariate calibration were used to show the high degree of relatedness between Escherichia coli HB101 and E. coli UB5201. Next, binary mixtures of these two phenotypically closely related E. coli strains were prepared and subjected to PyMS. Fully interconnected feedforward artificial neural networks (ANNs) were used to analyse the pyrolysis mass spectra...
