The aim was to investigate the effect of lotus seed resistant starch (LRS) on lactic acid (LA) conversion to butyric acid (BA) fermented by rat fecal microbiota to construct an acetyl CoA pathway. According to growth curves, the microbiota compositions at 10 and 36 h were further analyzed. The microbiota in the LRS group had higher richness and diversity compared to glucose (GLU) and high amylose maize starch (HAMS).

As antibodies are the main biological binder for hazards in food samples, their performance directly determines the sensitivity, specificity, and reproducibility of the developed immunoassay. The overwhelmingly used mammalian-derived antibodies usually suffer from complicated preparation, high cost, frequent bleeding of animals, and sometimes low titer and affinity.

The goals of this study were to evaluate the persistence and the virulence potential of Listeria monocytogenes isolated from beef carcasses obtained in processing facilities in the Southern region of Rio Grande do Sul, Brazil, based on pulsed field gel electrophoresis (PFGE), invasion ability in human colorectal carcinoma cells (HCT-116), InlA expression by western blot (WB) and identification of mutation points in the inlA . PFGE profiles demonstrated that L.

Toxoplasma gondii is an important intracellular parasitic protozoan with a variety of hosts, including chickens, which poses a potential threat to public health. However, little is known regarding overall T. gondii infection in chickens in China. Herein, the prevalence and risk factors associated with T. gondii infection in chickens in China were investigated using a meta-analysis. Forty studies regarding the prevalence of T.

Abstract

The purpose of this study was to isolate tea saponin from defatted C. oleifera cake and explore its potential antifungal activity and mechanism. UHPLC–MS/MS identified the compounds, and the antibacterial activity of tea saponin was determined by the inhibition zone method and double dilution method. In addition, the influence of tea saponin on the cell membrane, hyphae, and biofilm was studied to explore the antifungal mechanism of tea saponin.

The ethanol extracts of 155 different foodstuffs containing medicinal plants were investigated for their biofilm eradication activities against pathogenic bacteria. A combined method of a colorimetric microbial viability assay based on reduction of a tetrazolium salt (WST-8) and a biofilm formation technique on the 96-pins of a microtiter plate lid was used to screen the biofilm eradication activities of foodstuffs.

Natural hypersaline environments are inhabited by an abundance of prokaryotic and eukaryotic microorganisms capable of thriving under extreme saline conditions. Yeasts represent a substantial fraction of halotolerant eukaryotic microbiomes and are frequently isolated as food contaminants and from solar salterns.

Polycyclic aromatic hydrocarbon (PAHs) is an important organic contaminant substance in the environment. Their concentration monitoring is of great significance for predicting the potential environmental risk and protecting the organism safety. Here, molecularly imprinted polymers (MIPs) coating was prepared on zylon heat-resistant fiber by in situ polymerization, which was packed to a stainless steel needle to develop a needle-type device (NTD) for the analysis of PAHs.

Objective: The gut microecosystem is the largest microecosystem in the human body and has been proven to be linked to neurological diseases. The main objective of this study was to characterize the fecal microbiome, investigate the differences between epilepsy patients and healthy controls, and evaluate the potential efficacy of the fecal microbiome as a diagnostic tool for epilepsy.

Diallyl disulfide (DADS), a garlic extract also known as allicin, has been reported to have numerous biological activities, including anticancer, antifungal, and inflammation-inhibiting activities, among others. Although many studies have assessed whether DADS can treat Candida albicans infection in vitro, its in vivo function and the underlying mechanism are still not clear. Accumulated evidence has implicated the gut microbiota as an important factor in the colonization and invasion of C.

Objective

Brucellosis is a common bacterial zoonotic infection, and greater than half a million new cases are diagnosed annually. This study investigates the expression of Th2 and Th17 immunity-related factors (Th2-LCR lncRNA, IL-25, TRAF3IP2, and IL-17RB) in different stages of Brucella infections.

Material and Methods

In this study, the aim was to investigate the discriminatory power of molecular diagnostics based on mNGS and traditional 16S ribosomal RNA PCR among Nocardia species. A total of fourteen clinical isolates from patients with positive Nocardia cultures and clinical evidence were included between January 2017 and June 2020 in HeNan Provincial People’s Hospital.

Since the implementation of the “treat all” policy in China in 2016, there have been few data on the prevalence of transmitted drug resistance (TDR) in China. In this study, we describe TDR in patients newly diagnosed with human immunodeficiency virus (HIV) infection between 2016 and 2019 in Shenyang city, China. Demographic information and plasma samples from all newly reported HIV-infected individuals in Shenyang from 2016 to 2019 were collected.

The global coronavirus disease-2019 (COVID-19) pandemic has changed the prevalence and management of many pediatric infectious diseases, including acute otitis media (AOM). Coronaviruses are a group of RNA viruses that cause respiratory tract infections in humans.

Background
In the last years, several food alerts have identified high levels of pyrrolizidine alkaloids (PAs) in a wide variety of food products, highlighting their occurrence as a concerning food safety issue.
