  1. Cellular Uptake of Clostridium botulinum C2 Toxin Requires Acid Sphingomyelinase Activity [Cellular Microbiology: Pathogen-Host Cell Molecular Interactions]

    • Infection and Immunity

    • Clostridium botulinum C2 toxin consists of an enzyme component (C2I) and a binding component (C2II). Activated C2II (C2IIa) binds to a cell receptor, giving rise to lipid raft-dependent oligomerization, and it then assembles with C2I. The whole toxin complex is then endocytosed into the cytosol, resulting in the destruction of the actin cytoskeleton and cell rounding. Here, we showed that C2 toxin requires acid sphingomyelinase (ASMase) activity during internalization.

  2. OxyR2 Modulates OxyR1 Activity and Vibrio cholerae Oxidative Stress Response [Molecular Pathogenesis]

    • Infection and Immunity

    • Bacteria have developed capacities to deal with different stresses and adapt to different environmental niches. The human pathogen Vibrio cholerae, the causative agent of the severe diarrheal disease cholera, utilizes the transcriptional regulator OxyR to activate genes related to oxidative stress resistance, including peroxiredoxin PrxA, in response to hydrogen peroxide. In this study, we identified another OxyR homolog in V.

  3. The Tat Substrate SufI Is Critical for the Ability of Yersinia pseudotuberculosis To Cause Systemic Infection [Bacterial Infections]

    • Infection and Immunity

    • The twin arginine translocation (Tat) system targets folded proteins across the inner membrane and is crucial for virulence in many important human-pathogenic bacteria. Tat has been shown to be required for the virulence of Yersinia pseudotuberculosis, and we recently showed that the system is critical for different virulence-related stress responses as well as for iron uptake. In this study, we wanted to address the role of the Tat substrates in in vivo virulence.

  8. Listeria monocytogenes CadC Regulates Cadmium Efflux and Fine-tunes Lipoprotein Localization to Escape the Host Immune Response and Promote Infection

    • The Journal of Infectious Diseases

    • AbstractListeria monocytogenes is a major intracellular human foodborne bacterial pathogen. We previously revealed L. monocytogenes cadC as highly expressed during mouse infection. Here we show that L. monocytogenes CadC is a sequence-specific, DNA-binding and cadmium-dependent regulator of CadA, an efflux pump conferring cadmium resistance. CadC but not CadA is required for L. monocytogenes infection in vivo.

  9. Interventions to reduce the bacterial load in recycled broiler litter

    • Poultry Science

    • Two experiments were undertaken to evaluate the bacterial load in recycled litter between broiler flocks following addition of quicklime (T1), windrowing (T2), shallow fermentation (T3), and control (no intervention, T4). The first experiment was developed in field conditions in which the broiler houses were accompanied by 6 consecutive flocks and the effect of the treatments was assessed on enterobacteria and aerobic mesophiles.

  10. Reduction of Salmonella in ground chicken using a bacteriophage

    • Poultry Science

    • This study’s goal was to ascertain the effectiveness of a commercially available Salmonella bacteriophage during ground chicken production focusing on: water source, different Salmonella serovars, and time. Salmonella-free boneless, skinless chicken meat was inoculated with 4.0 Log CFU/cm2 of either a cocktail of 3 Salmonella isolates derived from ground chicken (GC) or a cocktail of 3 Salmonella strains not isolated from ground chicken (non-GC).

  11. Toxins, Vol. 9, Pages 113: A Review: Epigenetic Mechanism in Ochratoxin A Toxicity Studies

    • Toxins

    • Ochratoxin A (OTA) is a natural contaminant that has displayed nephrotoxicity and hepatotoxicity in mammals. It contaminates a great variety of foodstuffs and threatens people’s lives. The molecular mechanism of OTA-induced toxicity has been studied since 1965. Moreover, epigenetic mechanisms are also studied in OTA-induced toxicity. Additionally, the mode of OTA epigenetic research has been advanced in research hotspots. However, there is still no epigenetic study of OTA-induced toxicity.

      LacZ (β-galactosidase) is used to monitor the transcription of genes in reporter strains carrying the lacZ gene under the control of a promotor of interest. This protocol for LacZ activity determinations in Vibrio cholerae following detergent lysis results in 2.5-fold increase of LacZ activities compared to lysis with chloroform.

    • Journal of Bacteriology

    • Bacterial lipoproteins are embedded in the cell membrane of both Gram-positive and Gram-negative bacteria where they serve numerous functions central to cell envelope physiology. Lipoproteins are tethered to the membrane by an N-acyl-S-(mono/di)-acyl-glyceryl-cysteine anchor that is variably acylated depending on genera.
