  1. Nivalenol Mycotoxin Concerns in Foods: An Overview on Occurrence, Impact on Human and Animal Health and Its Detection and Management Strategies

    • Toxins
    • Mycotoxins are secondary metabolites produced by fungi that infect a wide range of foods worldwide. Nivalenol (NIV), a type B trichothecene produced by numerous Fusarium species, has the ability to infect a variety of foods both in the field and during post-harvest handling and management. NIV is frequently found in cereal and cereal-based goods, and its strong cytotoxicity poses major concerns for both human and animal health.

  2. Volatiles of antagonistic soil yeasts inhibit growth and aflatoxin production of Aspergillus flavus

    • Microbiological Research
    • Minimizing Aspergillus flavus growth is an effective strategy to mitigate aflatoxin contamination in food and agricultural products. In the present investigation, we attempted to utilize soil-associated yeasts from the Western and Eastern Ghats of India against A. flavus to reduce aflatoxin contamination. Forty-five yeast isolates were screened against A. flavus using overlay and dual plate assays.

  6. Listeria monocytogenes post-outbreak management - When could a food production be considered under control again?

    • International Journal of Food Microbiology
    • In cases of outbreaks, food business operators face inspections, recall actions and delisting by retailers. This could have happened to an Austrian meat processor whose products have been associated with a cluster of seven cases of listeriosis spread over the years 2015–2017. Sequencing of clinical and foodborne isolates by public health specialists raised the suspect of a single source outbreak since all strains were of MLST 155, cgMLST 1234.

  11. Measurement of Fumonisins in Maize Using a Portable Mass Spectrometer

    • Toxins
    • Fumonisins are a group of mycotoxins that routinely contaminate maize. Their presence is monitored at multiple stages from harvest to final product. Immunoassays are routinely used to screen commodities in the field while laboratory-based methods, such as mass spectrometry (MS), are used for confirmation.

  15. Constrained evolution of overlapping genes in viral host adaptation: Acquisition of glycosylation motifs in hepadnaviral precore/core genes

    • PLOS Pathogens
    • by Xupeng Hong, Stephan Menne, Jianming Hu Hepadnaviruses use extensively overlapping genes to expand their coding capacity, especially the precore/core genes encode the precore and core proteins with mostly identical sequences but distinct functions. The precore protein of the woodchuck hepatitis virus (WHV) is N-glycosylated, in contrast to the precore of the human hepatitis B virus (HBV) that lacks N-glycosylation.

    • Frontiers in Cellular and Infection Microbiology
    • Staphylococcus epidermidis is a major causative agent of prosthetic joint infections (PJI). The ability to form biofilms supports this highly selective pathogenic potential. In vitro studies essentially relying on phenotypic assays and genetic approaches have provided a detailed picture of the molecular events contributing to biofilm assembly. A major limitation in these studies is the use of synthetic growth media, which significantly differs from the environmental conditions S.
