Foodborne zoonotic trematode (FZT) infections are common neglected tropical diseases in Southeast Asia. Their complicated life cycles involve freshwater snails as intermediate hosts. A cross-sectional study was conducted in Yen Bai and Thanh Hoa provinces in North and Central Vietnam, to investigate the diversity of cercariae of potential FZT and to construct the phylogenetic relationship of trematode cercariae based on the Internal Transcribed Spacer 2 (ITS2) region.

The emerging spread of carbapenemase-producing Enterobacterales (CPE) strains, in particular, Klebsiella pneumoniae and Escherichia coli, has become a significant threat to hospitalized patients. Carbapenemase genes are frequently located on plasmids than can be exchanged among clonal strains, increasing the antibiotic resistance rate. The aim of this study was to determine the prevalence of CPE in patients upon their admission and to analyze selected associated factors.

Exudative epidermatitis (EE) or greasy pig disease (GPD) is a contagious disease of pig and endemic worldwide caused by toxigenic strains under genus Staphylococcus. The present study reported an outbreak of GPD in Champhai district of Mizoram adjoining to the southern border of Myanmar. A total of 60 samples were collected from 22 clinically affected animals and processed for isolation and identification of Staphylococcus spp.

BACKGROUND Fermentation, a traditional food preserving technique and an effective process, widely used to enrich the nutrients diversity and bioactivity of the fermented foods since ancient times. This study aimed at investigating the effects of various fermentation starters on the physicochemical, antioxidant, antimicrobial, and antidiabetic properties of the blueberry juices.

Background In recent years high‐pressure processing (HPP) of fruit products has steadily increased due to antimicrobial effectiveness and the retention of nutritional and quality attributes compared to conventional thermal technologies. Edible coatings are already being used to enhance the quality of minimally processed fruits. Thus, apple cubes (AC) and alginate‐vanillin coated apple cubes (AVAC) were high‐pressure processed (HPP, 400 MPa/5 min/35 °C).

To cope with the presence of unfavorable compounds, plants are capable to biotransform xenobiotics, translocate both parent compounds and metabolites, perform compartmentation and segregation at cellular or tissue level. Such a scenario also applies to mycotoxins, fungal secondary metabolites with a preeminent role in plant infection. In this work, we aimed to describe the effect of the interplay between Zea mays and aflatoxin B1 (AFB1) at the tissue and organ level.

The porcine respiratory tract harbours multiple microorganisms, and the interactions between these organisms could be associated with animal health status. Pasteurella multocida is a culturable facultative anaero...

Polyaromatic hydrocarbons are highly stable and can easily permeate through biological membranes due to their lipophilic nature. They are characterized by their ability to act at the site of application and even at sites distant to the zone of application. Any contamination associated with aquatic bodies due to the presence of PAHs can be assessed by investigating biochemical changes.

Selenium is a trace element necessary for the growth of organisms. Moreover, selenium supplementation can improve the immunity and fertility of the body, as well as its ability to resist oxidation, tumors, heavy metals, and pathogenic microorganisms. However, owing to the duality of selenium, excessive selenium supplementation can cause certain toxic effects on the growth and development of the body and may even result in death in severe cases.

Postharvest preservation and storage have a crucial impact on the technological quality and safety of grain. The important threat to stored grain quality and nutritional safety of cereal products is mould development and their toxic metabolites, mycotoxins.

Mycotoxin contamination causes significant economic loss to food and feed industries and seriously threatens human health. Aflatoxins (AFs) are one of the most harmful mycotoxins, which are produced by Aspergillus flavus, Aspergillus parasiticus, and other fungi that are commonly found in the production and preservation of grain and feed. AFs can cause harm to animal and human health due to their toxic (carcinogenic, teratogenic, and mutagenic) effects.

This study aimed to detect and quantify mycotoxins on building materials using innovative laser mass spectroscopy methods—silver-109/silver/gold nanoparticle-enhanced target surface-assisted laser desorption/ionisation mass spectrometry (109AgNPs, AgNPs and AuNPs SALDI). Results from SALDI-type methods were also compared with commonly used matrix-assisted laser desorption/ionization (MALDI) mass spectrometry.

The aim of this study was to investigate the opinions of meat consumers (n = 1780) on on-farm management of unhealthy pigs, whether support for treatment with antibiotics varies according with chance of recovery, and the effect of knowledge on the use of antibiotics on these opinions. Most participants believed that the use of antibiotics was the best solution for unhealthy pigs, and this was associated with a low level of knowledge about antibiotics.

Aims A. hydrophila is a zoonotic pathogen displaying resistance to multiple antibiotics. Here we aim to develop a candidate biocontrol agent against A. hydrophila. Methods and results In this study, we isolated and characterized the phage vB‐AhyM‐AP1 from sewage. It showed lytic activity against A. hydrophila strains. One‐step growth curve revealed that the latent period lasted for 40 min. The burst size of one lytic cycle was 1413 PFU/infected cell.

ABSTRACT Background Nanoscale tapioca starch (NTS) was successfully developed by high speed jet in our previous study. In this study, the adsorption capacity of Cu2+ onto NTS was further discussed. The optimal adsorption conditions ( pH, contact time, contact temperature, Initial Cu2+ concentration, and adsorbent concentration), adsorption kinetics, isotherms and thermodynamic were also evaluated.

BACKGROUND α‐lactalbumin (α‐La) was of great interest to the industry due to its excellent functional properties and nutritional value. Aqueous two‐phase flotation (ATPF) of thermo‐sensitive polymer poly (ethylene glycol‐ran‐propylene glycol) monobutyl ether (UCON) and KH2PO4 was applied to directly separate and purify α‐La from milk whey, which was purposed to simplify the production process and reduced cost of production.

ABSTRACT Biofilm is a predominant lifestyle of bacteria that comprises of cells as collectives enmeshed in a polymeric matrix. Biofilm formation is vital for bacterial species as it provides access to nutrients and protects the cells from environmental stresses. Here we show that interference in biofilm matrix production is a strategy by the competing bacterial species to reduce the ability of the other species to colonize a surface.
