  1. Surface-anchored liquid crystal droplets for the semi-quantitative detection of Aflatoxin B1 in food samples

    • Mon, 05/16/2022 - 04:00
    • Food Chemistry
    • Aflatoxin B1 (AFB1) is a common food mycotoxin that can cause various diseases. Therefore, reliable detection methods are required to ensure food safety against mycotoxins. In this study, we design a liquid–crystal (LC)-based assay for rapid detection of AFB1 in food samples. The surface-anchored LC droplets on glass (5CBSADrop) are obtained via a solvent evaporation method.

    • Veterinary Microbiology
    • Campylobacteriosis is a significant public health concern with Campylobacter jejuni and Campylobacter coli as main causative agents. Moreover, there is an increasing recognition of other pathogenic Campylobacter species and Campylobacter-like organisms as Arcobacter.

    • Sun, 05/15/2022 - 04:00
    • Fish & Shellfish Immunology
    • As a kind of environmental pollutant, heavy metal Cadmium (Cd) exists widely in the environment. It is well known that Cd can accumulate and cause damage in liver, kidney and other organs. However, there are few studies on the immune cytotoxicity of Cd to fish. In particular, there are few studies on the toxicity of Cd to the head kidney lymphocytes of common carp. In order to further explore these mechanisms, we established an Cd exposure model in vitro.

  5. Toxoplasma gondii outbreak in southern Brazil: heterogeneity of the serological humoral response in pregnant women and outcomes in newborns

    • Sun, 05/15/2022 - 04:00
    • Diagnostic Microbiology and Infectious Disease
    • The aim of the study was to describe the heterogeneity of the humoral immune response and pregnancy outcomes in infected women during an outbreak of toxoplasmosis. Forty-two pregnant women referred to the University Hospital of Santa Maria (HUSM), RS, Brazil in 2018 and 2019, were evaluated. Clinical symptoms were reported in 33.3% of the patients. The majority (64.3%) of symptomatic pregnant women had anti T. gondii IgM antibodies index >7.0.

  6. The impact of environmental pH on the gut microbiota community structure and short chain fatty acid production

    • Sun, 05/15/2022 - 04:00
    • FEMS Microbiology Ecology
    • Environmental pH is a critical parameter for maintenance of the gut microbiota. Here, the impact of pH on the gut microbiota luminal and mucosal community structure and short chain fatty acid (SCFA) production was evaluated in vitro, and data compiled to reveal a donor-independent response to an increase or decrease in environmental pH. The results found that raising environmental pH significantly increased luminal community richness and decreased mucosal community evenness.

    • Skin and soft tissue inflammatory diseases of bacterial origin occupy a significant part of hospitalizations to emergency departments. One of the most common causes of sepsis is soft tissue infection, which accounts for about a quarter of all nosocomial infections. The aim of this study was to determine the differences in microbial landscape and antibiotic susceptibility of soft tissue infection pathogens among adults and children during the period 2018–2020.

  9. Vibrio cholerae Chromosome Partitioning without Polar Anchoring by HubP

    • Sat, 05/14/2022 - 04:00
    • Genes
    • Partition systems are widespread among bacterial chromosomes. They are composed of two effectors, ParA and ParB, and cis acting sites, parS, located close to the replication origin of the chromosome (oriC). ParABS participate in chromosome segregation, at least in part because they serve to properly position sister copies of oriC. A fourth element, located at cell poles, is also involved in some cases, such as HubP for the ParABS1 system of Vibrio cholerae chromosome 1 (ch1).

  10. Local and Global Protein Interactions Contribute to Residue Entrenchment in Beta-Lactamase TEM-1

    • Sat, 05/14/2022 - 04:00
    • Antibiotics
    • Due to their rapid evolution and their impact on healthcare, beta-lactamases, protein degrading beta-lactam antibiotics, are used as generic models of protein evolution. Therefore, we investigated the mutation effects in two distant beta-lactamases, TEM-1 and CTX-M-15. Interestingly, we found a site with a complex pattern of genetic interactions. Mutation G251W in TEM-1 inactivates the protein’s function, just as the reciprocal mutation, W251G, does in CTX-M-15.

    • New strategies are needed to fight the emergence of multidrug-resistant bacteria caused by an overuse of antibiotics in medical and veterinary fields. Due to the importance of biofilms in clinical infections, antibiofilm peptides have a great potential to treat infections. In recent years, an increased interest has emerged in antimicrobial peptides (AMPs). One of the richest sources of AMPs is represented by amphibian skin.

    • Therapeutic Advances in Infectious Disease
    • Direct-acting antivirals (DAAs) achieve high hepatitis C virus (HCV) cure rates and are forgiving to missed doses, but adherence–efficacy relationships have not been well defined. Traditional adherence measures (e.g. pill counts, self-report and pharmacy refills) over-estimate medication adherence. Newer technology-based tools have been used to provide more objective adherence data.

    • Microbes and Infection
    • As a pathogenic microorganism, Listeria monocytogenes is widely used in the research of bacterial pathogenesis and host defense. The phagosomal escape of Listeria monocytogenes is essential for its replication in the cytoplasm of the host. Here, we reported that the protein abundance of the Six-transmembrane epithelial antigen of the prostate 3 (Steap3) was decreased upon Listeria monocytogenes infection compared to uninfected cells in macrophages.

    • International Journal of Food Microbiology
    • This study was aimed to examine the membrane damage mechanism of gallic acid (GA) on Yersinia enterocolitica BNCC 108930, and to explore whether GA can prolong the shelf life of pork. The minimal inhibitory concentration (MIC) of GA against Y. enterocolitica was determined by adopting the broth microdilution method. Second, an investigation was conducted on the morphological and physiological variations of Y. enterocolitica after the GA treatment.

    • Staphylococcus aureus (S. aureus) is one of the main pathogens in different raw milk and dairy products, which may lead to economic losses. Staphylococcus aureus is a significant and costly public health concern because it may enter the human food chain and contaminate milk causing foodborne illness. This study aimed to investigate the prevalence, antimicrobial susceptibility and virulence genes of S. aureus in raw milks.

    • Olive farming is one of the key agricultural activities in Jordan, where nearly 70% of the cultivated land in Jordan is covered with olive trees. Olive harvesting generates massive quantities of agricultural waste which will be an environmental burden if not managed properly. The present study introduces the use of novel co-processed biomass extracted from the olive tree leaves for the adsorption of lead from contaminated water.
