Salmonella enterica serovar Typhi is the etiologic agent of typhoid fever, a major public health problem in the developing world. Moving toward and adhering to the intestinal epithelium represents key initial steps of infection by S. Typhi. We examined the role of the S. Typhi yrbE gene, which encodes an inner membrane phospholipid transporter, in these interactions with epithelial cells. Disruption of yrbE resulted in elevated expression of flagellin and a hypermotile phenotype.

Asian‐origin H5N8 highly pathogenic avian influenza (HPAI) viruses of the H5 Goose/Guangdong/96 lineage, clade 2.3.4.4 group B reached South Africa by June 2017. By the end of that year, 5.4 million layers and broiler chickens died or were culled, with total losses in the poultry industry estimated at US$ 140 million, and thousands of exotic birds in zoological collections, endangered endemic species and backyard poultry and pet birds also perished.

Significance and Impact of the Study: Prevalence, genetic diversity and geographic distribution of SAFV in Italy is currently unknown. This study represents the first detection of SAFV in sewage samples in Italy, suggesting that it is circulating in the population despite lack of clinical reporting. Whether the virus is associated with asymptomatic cases or with undetected gastroenteritis or respiratory illness is unknown.

Texture‐modified foods (TMFs) and thickened fluids have been used as a therapeutic strategy in the management of food intake in the elderly and people with dysphagia. Despite recent advances in describing rheological features of TMFs for dysphagia management, there is still paucity of research regarding the sensory attributes, therapeutic thickness levels, and swallowing safety of these foods.

Postharvest techniques are widely used for the handling and storage of fresh horticultural crops. Some of these techniques are interesting for use with wine grapes to improve the quality of wine. In this review, we consider the postharvest techniques that are already commercially used in the wine sector and others that may be significant in inducing or extracting the aroma from grapes to produce high‐quality wines.

Food safety is a very complex issue. The food that reaches the plate from the farm is exposed to many hazards in processing methods and each of those steps is likely to contribute, indirectly or directly, to contaminants and pathogens that ultimately make the food unsafe. Consumers would always wish for 100% product safety; even regulators want to ensure 100% safety of the product and protect consumers.

Captive and free‐ranging wild bears can carry and transmit several zoonotic pathogens. A review of nearly 90 years of scientific publications concerning confirmed and potential zoonotic diseases that can be present in any of the eight species of bears in the world was conducted. The findings were organized amongst the following disease sections: bacterial, viral, protozoal, mycotic, helminth and arthropod‐borne.

The purpose of this study was to find out the mechanism of quinolone resistance in Shigella sp. isolated from environmental water samples from various parts of Kolkata, India. Out of 196 Shigella sp. isolated from 2014‐17, we selected 32 Shigella isolates for antimicrobial susceptibility tests.

Listeria monocytogenes, the causative agent of listeriosis, is a foodborne pathogen with significant public health and economic impacts. The control of pathogen presence in food requires rapid and sensitive methods. Real-time PCR is considered to be a fast and accurate tool for the detection of foodborne pathogens. A crucial step for the success of a culture-independent PCR-based detection is the template DNA extraction.

In this work, a graphene oxide-based composite (DABP-GO) was prepared by aminating graphene oxide (GO) with the diazonium salt of 4,4′-diaminobiphenyl (DABP). The DABP-GO composite was characterized by scanning electron microscopy, infrared spectroscopy, and nitrogen adsorption-desorption. The DABP-GO showed to be an effective solid-phase extraction (SPE) adsorbent for carbamate pesticides.

With increasing concern related to sustainable chemistry, we investigated the biosorption of Pb2+ ions from aqueous medium using an environmental friendly and economic biosorbent Bougainvillea spectabilis (BS). The BS was modified effectively using citric acid by hydrothermal method.

M. Kaddoura et al. In 2018, a hepatitis A virus outbreak was identified among internally displaced persons in Syria. Sequence analysis based on the viral protein 1/2A junction revealed that the causative virus belonged to genotype IB. A high displacement rate, deteriorated sanitary and health conditions, and poor water quality likely contributed to this outbreak.

Proteus mirabilis is commonly considered to be an opportunistic pathogen causing urinary tract infections (UTIs) in humans. However, some strains of P. mirabilis were found to be associated with food poisoning outbreaks, with the pathogenic mechanism still unclear. In our study, we described a novel strain of P. mirabilis C02011 isolated from patients’ specimens in a food poisoning in China. In order to determine its gastrointestinal pathogenicity, experiments were performed to compare P.
