  1. Prevalence of Carriage of Shiga Toxin-Producing Escherichia coli Serotypes O157:H7, O26:H11, O103:H2, O111:H8, and O145:H28 among Slaughtered Adult Cattle in France [Public and Environmental Health Microbiology]

    • Applied and Environmental Microbiology

    • The main pathogenic enterohemorrhagic Escherichia coli (EHEC) strains are defined as Shiga toxin (Stx)-producing E. coli (STEC) belonging to one of the following serotypes: O157:H7, O26:H11, O103:H2, O111:H8, and O145:H28. Each of these five serotypes is known to be associated with a specific subtype of the intimin-encoding gene (eae).

  2. Individual Predisposition to Staphylococcus aureus Colonization in Pigs on the Basis of Quantification, Carriage Dynamics, and Serological Profiles [Public and Environmental Health Microbiology]

    • Applied and Environmental Microbiology

    • Previous research on Staphylococcus aureus in pigs focused on livestock-associated methicillin-resistant S. aureus (MRSA) and had a qualitative cross-sectional design. This study aimed to elucidate the frequency, load, and stability of S. aureus nasal carriage in pigs over time and investigated possible associations between carriage and immune response. Nasal swabs were collected three times weekly from 480 tagged adult pigs in 20 Danish production farms. S.

  6. Chloramphenicol and tetracycline decrease motility and increase invasion and attachment gene expression in specific isolates of multidrug-resistant Salmonella enterica serovar Typhimurium

    • Frontiers in Microbiology

    • Brian William Brunelle, Bradley L. Bearson and Shawn M.D. Bearson Salmonella enterica serovar Typhimurium is one of the most common serovars isolated from humans and livestock, and over 35% of these isolates are resistant to three or more antibiotics.

  7. A D, D-carboxypeptidase is required for Vibrio cholerae halotolerance

    • Environmental Microbiology

    • The biological roles of low molecular weight penicillin-binding proteins (LMW PBP) have been difficult to discern in Gram-negative organisms. In E. coli, mutants lacking these proteins often have no phenotype, and cells lacking all 7 LMW PBPs remain viable. In contrast, we report here that Vibrio cholerae lacking DacA-1, a PBP5 homolog, displays slow growth, aberrant morphology, and altered peptidoglycan (PG) homeostasis in LB medium, as well as a profound plating defect.

  8. Multistate foodborne hepatitis A outbreak among European tourists returning from Egypt- need for reinforced vaccination recommendations, November 2012 to April 2013

    • Eurosurveillance

    • A multistate outbreak of hepatitis A virus (HAV) among European travellers returning from Egypt occurred between November 2012 and April 2013. A total of 14 European Union (EU)-European Free Trade Association (EFTA) countries reported 107 cases. Twenty-one cases from six countries were affected by strains of sub-genotype IB harbouring identical RNA sequences, suggesting a common source outbreak.

    • World Mycotoxin Journal

    • Since the discovery of aflatoxins in the 1960s, much research has focused on detecting the toxins in contaminated food and feedstuffs in the interest of public safety. Most traditional detection methods involved lengthy culturing and/or separation techniques or analytical instrumentation and complex, multistep procedures that required destruction of samples for accurate toxin determination.

  13. No Evidence for a Culturable Bacterial Tetrodotoxin Producer in Pleurobranchaea maculataGastropoda: Pleurobranchidae) and Stylochoplana sp. (Platyhelminthes: Polycladida)

    • Toxins

    • Tetrodotoxin (TTX) is a potent neurotoxin found in the tissues of many taxonomically diverse organisms. Its origin has been the topic of much debate, with suggestions including endogenous production, acquisition through diet, and symbiotic bacterial synthesis. Bacterial production of TTX has been reported in isolates from marine biota, but at lower than expected concentrations. In this study, 102 strains were isolated from Pleurobranchaea maculata (Opisthobranchia) and Stylochoplana sp.

    • World Mycotoxin Journal

    • Ochratoxin A (OTA), which is found in a variety of food products, is associated with the development of nephrotoxicity and carcinogenicity in rats and has raised public health concerns. A previous study in our laboratory indicated that OTA exposure induced cytotoxicity by decreasing global DNA methylation in vitro. However, the relationship between OTA-induced nephrotoxicity and DNA methylation changes in vivo remains unclear.

  25. Rapid Multiple Immunoenzyme Assay of Mycotoxins

    • Toxins

    • Mycotoxins are low molecular weight fungal metabolites that pose a threat as toxic contaminants of food products, thereby necessitating their effective monitoring and control. Microplate ELISA can be used for this purpose, but this method is characteristically time consuming, with a duration extending to several hours. This report proposes a variant of the ELISA method for the detection and quantification of three mycotoxins, ochratoxin A, aflatoxin B1 and zearalenone, in the kinetic regime.
