Clostridioides difficile is a Gram-positive, toxin-producing bacteria that major cause of hospital-acquired infection.1Clements A.C. et al.Lancet Infect Dis. 2010; 10: 395-404Abstract Full Text PDF PubMed Scopus (138) Google Scholar During C infection (CDI), the bacterial toxins toxin A (TcdA) and B (TcdB) are produced, which intestinal epithelial injury inflammation symptoms including diarrhea...

In a recent article (3), Norén et al. reported an extensive evaluation of illumigene Clostridium difficile compared with the cell culture cytotoxin B assay (CTBA) and/or toxigenic culture (TC) of cytotoxin-producing C. difficile isolates. The illumigene assay utilizes loop-mediated isothermal DNA amplification (LAMP) technology to detect the pathogenicity locus (PaLoc) of toxigenic Clostridium ...

We have traced the evolution patterns of 2480 transmembrane transporters from five complete genome sequences spanning the entire Hemiascomycete phylum: Saccharomyces cerevisiae, Candida glabrata, Kluyveromyces lactis, Debaryomyces hansenii, and Yarrowia lipolytica. The use of nonambiguous functional and phylogenetic criteria derived from the TCDB classification system has allowed the identifica...

Molecular typing analysis showed that both case-patients had a monoclonal infection caused by C. diffi cile ribotype 027. Both isolates had tcdA, tcdB, and cdtB and had a deletion in tcdC (data not shown). In summary, the described severe cases of C. diffi cile infection in Chile were caused by epidemic C. diffi cile ribotype 027. One of these casepatients required urgent colectomy. These resul...

The transition from G2 phase into mitosis is driven by the kinase activity of the Cdk1/ cyclin B complex. Cdk1 becomes activated in late G2 phase by mitotic kinases, including Aurora A and mitotic Cdc25 phosphatases. About 10 y ago, Jackman and coworkers identified the centrosomes as a scaffold for the activation of Cdk1-cyclinB,1 and Hirota et al. demonstrated that Cdk1 activation is induced b...

Introduction / objectives Clostridium difficile reporting is mandatory in England, numbers have increased since the mid-1990s with over 25 000 reported per year. At Imperial College Healthcare it was observed that isolation of C. difficile from stool did not always reflect clinical disease; particularly when testing was changedto detection of glutamate dehydrogenase (GDH) and the tcdB gene by P...

وراثت مقاومت سفیدبالک گلخانه، Trialeurodes vaporariorum Westwood (Hemiptera: Aleyrodidae)، به دو ترکیب ایمیداکلوپرید و کلرپایریفوس مورد مطالعه قرار گرفت. در این پژوهش، از جمعیت فیلستان ورامین (FL) عنوان والد مقاوم فردیس کرج (FR) حساس استفاده شد. مقدار ترتیب حدودا 62/13 91/14 برابر بود. عدم وجود اختلاف معنی‌دار LC50 روی تلاقی‌های F1 (R♂×S♀) Fʹ1 (R♀×S♂) نشان داد که T. نوع اتوزومی (غیرجنسی) است. ه...
