The food industry is advancing at a rapid pace and consumer sensitivity to food safety scares and food fraud scandals is further amplified by rapid communication such as by social media. Academia, regulators, and industry practitioners alike struggle with an evolving issue regarding new terms and definitions including food fraud, food authenticity, food integrity, food protection, economically motivated adulteration, food crime, food security, contaminant, adulterant, and others.

This study determines the natural product biosynthesis and full coding potential within the bacterial genus Aquimarina. Using comprehensive phylogenomics and functional genomics, we reveal that phylogeny instead of isolation source [host‐associated (HA) vs. free‐living (FL) habitats] primarily shape the inferred metabolism of Aquimarina species.

While the dynamics of microbial community assembly driven by environmental perturbations have been extensively studied, our understanding is far from complete, particularly for light‐induced perturbations. Extremely halophilic communities thriving in coastal solar salterns are mainly influenced by two environmental factors ‐ salt concentrations and high sunlight irradiation.

In some countries, use of horsemeat as a food is inhibited by ethical and cultural concerns. However, horsemeat has potential health benefits, such as low fat and high unsaturated fatty acid content compared with other meats, as well as attractive sensory properties. Although there are many contradictory data on the dietary value in relation to human health, the effects of horsemeat have not been studied to a large extent.

ABSTRACT Objectives Guidelines recommend antibiotic treatment for every episode of asymptomatic bacteriuria throughout pregnancy in order to reduce maternal and fetal complications. We evaluated intra- and post-partum, as well as puerperal maternal and neonatal outcomes of an untreated group of pregnant women with asymptomatic bacteriuria at term. Methods This was a single center prospective cohort study.

ABSTRACT The incidence of opportunistic yeast infections in humans has been increasing over recent years. These infections are difficult to treat and diagnose, in part due to the large number and broad diversity of species that can underlie the infection.

To successfully colonize host tissues, bacteria must respond to and detoxify many different host-derived antimicrobial compounds, such as nitric oxide (NO). NO has direct antimicrobial activity through attack on iron-sulfur (Fe-S) cluster-containing proteins. NO detoxification plays an important role in promoting bacterial survival, but it remains unclear if repair of Fe-S clusters is also important for bacterial survival within host tissues.

Enteropathogenic Escherichia coli (EPEC) is a leading cause of moderate to severe diarrhea among young children in developing countries, and EPEC isolates can be subdivided into two groups. Typical EPEC (tEPEC) bacteria are characterized by the presence of both the locus of enterocyte effacement (LEE) and the plasmid-encoded bundle-forming pilus (BFP), which are involved in adherence and translocation of type III effectors into the host cells.

Infection with Coxiella burnetii, the causative agent of Q fever, can result in life-threatening persistent infection. Reactogenicity hinders worldwide implementation of the only licensed human Q fever vaccine. We previously demonstrated long-lived immunoreactivity in individuals with past symptomatic and asymptomatic Coxiella infection (convalescents) to promiscuous HLA class II C. burnetii epitopes, providing the basis for a novel T-cell targeted subunit vaccine.

In this study, a novel recombinant attenuated Yersinia pseudotuberculosis PB1+ strain (10069) engineered with yopK yopJ asd triple mutations was used to deliver a Y. pestis fusion protein, YopE amino acid 1 to 138-LcrV (YopENt138-LcrV), to Swiss Webster mice as a protective antigen against infections by yersiniae.

Nontuberculous mycobacteria (NTM) are highly drug-resistant, opportunistic pathogens that can cause pulmonary disease. The outcomes of the currently recommended treatment regimens are poor, especially for Mycobacterium abscessus. New or repurposed drugs are direly needed. Auranofin, a gold-based antirheumatic agent, was investigated for Mycobacterium tuberculosis. Here, we test auranofin against NTM in vitro and ex vivo.

Salmonella genomic island 3 (SGI3) was first described as a chromosomal island in Salmonella 4,[5],12:i:–, a monophasic variant of Salmonella enterica subsp. enterica serovar Typhimurium. The SGI3 DNA sequence detected from Salmonella 4,[5],12:i:– isolated in Japan was identical to that of a previously reported one across entire length of 81 kb.

In the quest for new antibacterial lead structures, activity screening against Mycobacterium tuberculosis identified antitubercular effects of gallic acid derivatives isolated from the Nigerian mistletoe Loranthus micranthus. Structure-activity relationship studies indicated that 3-O-methyl-alkylgallates comprising aliphatic ester chains with four to eight carbon atoms showed the strongest growth inhibition in vitro against M. tuberculosis, with a MIC of 6.25 μM.
