  • Identification of Dihydropyrimidine Dehydrogenase as a virulence factor essential for the survival of Entamoeba histolytica in glucose‐poor environments

    Updated: 2012-09-29 01:41:23
    In this study, we were intrigued to know how this parasite reacts to changes in glucose availability and we addressed this issue by performing a DNA microarray analysis of gene expression. Results show that parasites that were adapted to growth in absence of glucose increased their virulence and altered the transcription of several genes. One of these genes is the dihydropyrimidine dehydrogenase (DPD), which is involved in degradation of pyrimidines. We showed that this gene is crucial for the parasite's growth when the availability of glucose is limited. These data contribute to our understanding of the parasite's ability to survive in glucose‐poor environments and reveal a new role for the DPD enzyme. (Source: Cellular Microbiology)

  • Genetic diversity, virulence genes and antimicrobial resistance of Salmonella Enteritidis isolated from food and humans over a 24-year period in Brazil.

    Updated: 2012-09-28 14:00:11
    In conclusion, the nalidixic acid resistance observed after 1996 is indicative of an increase in the use of this drug. It may be suggested that these 128 strains might have descended from a common ancestor that differed little over 24 years and has been both contaminating food and humans and causing disease for more than two decades in Brazil.

  • Potent effects and mechanisms for modification of the crosstalk between macrophages and adipocytes by lactobacilli

    Updated: 2012-09-28 07:13:38
    ABSTRACT The murine macrophage‐like cell line J774.1 was treated with heat‐killed cells of Lactobacillus GG (LGG) and L. gasseri TMC0356 (TMC 0356). Interleukin (IL)‐6, IL‐12, and tumor necrosis factor‐α were profiled from the J774.1 cells using enzyme‐linked immunoSorbent assay methods. The conditioned medium from cultured J774.1 cells was transferred to the preadipocyte cell line 3T3‐L1 (which is a mouse embryonic fibroblast‐adipose‐like cell line). Growth and differentiation of 3T3‐L1 cells were monitored by analyzing lipid accumulation and expression of peroxisome proliferator‐activated receptor (PPAR)‐γ mRNA. The medium conditioned by 3T3‐L1 cells was added to J774.1 cells and the cytokines in the supernatant were analyzed. Lipid accumulation in 3T3‐L1 ce...

    Updated: 2012-09-28 07:11:39
    In this study, we recruited pneumonia patients with and without pH1N1 infection and characterized their oropharyngeal microbiota by unbiased high‐throughput sequencing method. While there were no significant differences in common bacterial pneumonia‐causative agents – Acinetobacter and Streptococcus species, previously unreported Pseudomonas species equipping with chemotaxis and flagellar assembly genes significantly increased (>20 fold) in pH1N1‐infected group. Bacillus and Ralstonia species that also increased significantly (5‐10 fold) were also found to possess similar signaling and motility genes. In contrast, none of such genes were found in oral commensal Prevotella, Veillonella and Neisseria species that decreased significantly, and in neither Acinetobacter nor 10 out o...

  • Bacterial chemotaxis: the early years of molecular studies.

    Updated: 2012-09-27 10:30:03
    Authors: Hazelbauer GL Abstract This review focuses on the early years of molecular studies of bacterial chemotaxis and motility, beginning in the 1960s with Julius Adler's pioneering work. It describes key observations that established the field and made bacterial chemotaxis a paradigm for the molecular understanding of biological signaling. Consideration of those early years includes aspects of science seldom described in journals: the accidental findings, personal interactions, and scientific culture that often drive scientific progress.

  • Network news: the replication of kinetoplast DNA.

    Updated: 2012-09-27 10:30:02
    Authors: Jensen RE, Englund PT Abstract One of the most fascinating and unusual features of trypanosomatids, parasites that cause disease in many tropical countries, is their mitochondrial DNA. This genome, known as kinetoplast DNA (kDNA), is organized as a single, massive DNA network formed of interlocked DNA rings. In this review, we discuss recent studies on kDNA structure and replication, emphasizing recent developments on replication enzymes, how the timing of kDNA synthesis is controlled during the cell cycle, and the machinery for segregating daughter networks after replication.

  • Reduced Incidence of Pneumonia in Influenza Vaccinated Solid Organ Transplant Recipients with Influenza Disease

    Updated: 2012-09-27 04:00:00
    Abstract: Whether influenza vaccination influences the severity of illness in cases of clinical failure in solid organ transplant recipients (SOTR) receiving influenza vaccine has not been extensively studied. Our goal was to evaluate the frequency of influenza vaccination among SOTR with influenza disease and its impact on the illness severity during the 2010‐2011 season. Adult SOTR with confirmed influenza infection were included from December‐2010 to April‐2011. Follow‐up data were recorded and antibody titers determined using a microneutralization assay. Sixty‐four SOTR were included in the study, 10 (15.6%) with severe disease, requiring ICU admission, of which 4 (6.3%) died. Of them, 34 (53.1%) received the 2010‐2011 seasonal influenza vaccine and 32 (50.0%) the 2009‐H1...

  • Topology of the microsomal glycerol‐3‐phosphate acyltransferase Gpt2p/Gat1p of Saccharomyces cerevisiae

    Updated: 2012-09-27 04:00:00
    Summary All glycerophospholipids are made from phosphatidic acid, which, according to the traditional view, is generated at the cytosolic surface of the ER. In yeast, phosphatidic acid is synthesized de novo by two acyl‐CoA dependent acylation reactions. The first is catalyzed by one of the two homologous glycerol‐3‐phosphate acyltransferases Gpt2p/Gat1p and Sct1p/Gat2p, the second by one of the two 1‐acyl‐sn‐glycerol‐3‐phosphate acyltransferases Slc1p and Ale1p/Slc4p. To study the biogenesis and topology of Gpt2p we observed the location of dual topology reporters inserted after various transmembrane helices. Moreover, using microsomes, we probed the accessibility of natural and substituted cysteine residues to a membrane impermeant alkylating agent and tested the protease...

  • Analysis of transmitted drug resistance in Spain in the years 2007–2010 documents a decline in mutations to the non‐nucleoside drug class

    Updated: 2012-09-27 04:00:00
    Clin Microbiol Infect AbstractWe have studied transmitted drug resistance (TDR) in 1.864 antiretroviral‐naïve patients entering CoRIS (Spain) during 2007–2010. An overall 8.58% TDR was observed (3.92%, nucleoside reverse transcriptase inhibitors (NRTIs); 3.86%, non‐nucleoside reverse transcriptase inhibitors (NNRTIs); 2.31%, protease inhibitors), with a significant decreasing trend over time for NNRTIs (5.53%, 2007; 2.45%, 2010; p for trend = 0.044). Non‐B subtype prevalence was 15.93%, with a significant increase (11.95%, 2007; 18.14%, 2010; p for trend = 0.018), mainly related to immigration. Having no formal education increased the risk of TDR to NNRTIs (OR, 7.26), and carrying a non‐B subtype reduced the risk of TDR to NRTIs (OR, 0.27). These findings may have import...

  • Determinants of substrate specificity and biochemical properties of the sn‐glycerol‐3‐phosphate ATP binding cassette transporter (UgpB–AEC2) of Escherichia coli

    Updated: 2012-09-27 04:00:00
    Summary Under phosphate starvation conditions, Escherichia coli can utilize sn‐glycerol‐3‐phosphate (G3P) and G3P diesters as phosphate source when transported by an ATP binding cassette importer composed of the periplasmic binding protein, UgpB, the transmembrane subunits, UgpA and UgpE, and a homodimer of the nucleotide binding subunit, UgpC. The current knowledge on the Ugp transporter is solely based on genetic evidence and transport assays using intact cells. Thus, we set out to characterize its properties at the level of purified protein components. UgpB was demonstrated to bind G3P and glycerophosphocholine with dissociation constants of 0.68 ± 0.02 μM and 5.1 ± 0.3 μM, respectively, while glycerol‐2‐phosphate (G2P) is not a substrate. The crystal structure...

  • Structure of WbdD: a bifunctional kinase and methyltransferase that regulates the chain length of the O antigen in Escherichia coli O9a

    Updated: 2012-09-27 04:00:00
    Summary The Escherichia coli serotype O9a O‐antigen polysaccharide (O‐PS) is a model for glycan biosynthesis and export by the ATP‐binding cassette transporter‐dependent pathway. The polymannose O9a O‐PS is synthesized as a polyprenol‐linked glycan by mannosyltransferase enzymes located at the cytoplasmic membrane. The chain length of the O9a O‐PS is tightly regulated by the WbdD enzyme. WbdD first phosphorylates the terminal non‐reducing mannose of the O‐PS and then methylates the phosphate, stopping polymerization. The 2.2 Å resolution structure of WbdD reveals a bacterial methyltransferase domain joined to a eukaryotic kinase domain. The kinase domain is again fused to an extended C‐terminal coiled‐coil domain reminiscent of eukaryotic DMPK (Myotonic Dystrophy P...

  • Mycoredoxin‐1 is one of the missing links in the oxidative stress defence mechanism of Mycobacteria

    Updated: 2012-09-27 04:00:00
    We report a novel mycothiol‐dependent reductase (mycoredoxin‐1) with a CGYC catalytic motif. With mycoredoxin‐1 and mycothiol deletion strains of Mycobacterium smegmatis, we show that mycoredoxin‐1 and mycothiol are involved in the protection against oxidative stress. Mycoredoxin‐1 acts as an oxidoreductase exclusively linked to the mycothiol electron transfer pathway and it can reduce S‐mycothiolated mixed disulphides. Moreover, we solved the solution structures of oxidized and reduced mycoredoxin‐1, revealing a thioredoxin fold with a putative mycothiol‐binding site. With HSQC snapshots during electron transport, we visualize the reduction of oxidized mycoredoxin‐1 as a function of time and find that mycoredoxin‐1 gets S‐mycothiolated on its N‐terminal nucleophili...

  • Cross‐reactive Antibody Response to the Pandemic A (H1N1) 2009 Influenza Virus induced by vaccination with a seasonal trivalent influenza vaccine: A Longitudinal Study of Three Influenza Seasons in Japan.

    Updated: 2012-09-26 17:42:41
    ABSTRACT The cross‐reactivity of antibody to the swine‐origin pandemic influenza A (H1N1) 2009 virus induced by vaccination with a seasonal trivalent influenza vaccine was studied. Paired sera from a cohort of adult volunteers vaccinated with a trivalent seasonal influenza vaccine every year from 2006 to 2008 were collected each year and tested by hemagglutination inhibition (HI) for antibody against the pandemic influenza A (H1N1) 2009 virus. There was little increase in the geometric mean titer overall; a slight increase was detected in the sera obtained in the 2007–2008 season but not in the other two seasons. The proportion of individuals with HI antibody titer ≥1:40 did not change significantly from year to year. These results indicated that cross‐reactivity of the antibodie...

  • A novel function for the competence inducing peptide, XIP, as a cell death effector of Streptococcus mutans

    Updated: 2012-09-26 04:00:00
    Abstract In Streptococcus mutans, ComX, an alternative sigma factor, drives the transcription of the ‘late‐competence genes’ required for genetic transformation. ComX activity is modulated by inputs from two signaling pathways, ComDE and ComRS, that respond to the competence‐stimulating peptide (CSP) and the SigX‐inducing peptide (XIP), respectively. In particular, the comRS, encoding the ComR regulatory protein and the ComS precursor to XIP, functions as the proximal regulatory system for ComX activation. Here, we investigated the individual and combinatorial effects of CSP and XIP on genetic transformation and cell killing of S. mutans. Our transformation results confirm the recent reports by Mashburn‐Warren et al. and Desai et al. that XIP functions optimally in a chemica...
