Salmonella enterica serovar Typhimurium (S. Typhimurium) is exposed to biotic and abiotic stresses. The survival of Salmonella in nature depends on the global regulators like cAMP receptor protein (CRP). The role of CRP in the phenotypic characteristics and stress tolerance was elucidated in S. Typhimurium using a crp gene null mutant (Δcrp). A 1.6‐fold decrease in the cell size, a two‐fold...

Waste Printed circuit boards (PCBs) are one of the most valuable and recycled components of electronic waste due to the presence of precious metals such as copper, silver, gold and palladium. The rejects of the PCB recycling process, named non-metal fraction (NMF) have continuously been sent to landfills. Several researchers have proposed alternative use of NMF as secondary materials such as...

Authentication of dairy and meat products is important to ensure fair competition, consumer benefit, and food safety. The large difference in price between camel and cow milk may be an incentive to adulterate camel dairy products with cow-derived foodstuffs. However, no studies so far have used triplex real-time PCR with an endogenous control to identify camel and cow origins in dairy and meat...

Non-aureus staphylococci (NAS) are predominantly isolated from bovine milk samples of quarters suffering from subclinical mastitis. They are also abundantly present on dairy cows' teat apices and can be recovered from bovine fecal samples, as recently described. Differences in ecology, epidemiology, effect on udder health, and virulence or protective traits have been reported among the species...

Predictions of drug residues in milk are critical in food protection and are a major consideration in the economics of treatment of mastitis in dairy cows. Nonlinear mixed-effects modeling (NLME) has been advocated as a suitable pharmaco-statistical method for the study of drug residues in milk. Recent developments in physiologically based pharmacokinetic (PBPK) modeling of intramammary drugs...

Author(s): Xu Zhang, Li Ling, Zhiyong Li, Jufang Wang Worldwide, Listeria monocytogenes is a common foodborne pathogen and serotyping is necessary for traceability and surveillance. Due to high accuracy and speed, PCR is commonly used for serotyping by targeting specific genes, such as lmo1118 and ORF2110 for 1/2c-3c and 4b-4d-4e, respectively. Single nucleotide polymorphisms (SNPs) are single...

Staphylococcal enterotoxins are the most common cause of foodborne intoxications (staphylococcal food poisoning) and cause a wide range of diseases. With at least six variants staphylococcal enterotoxin C (SEC) stands out as particularly diverse amongst the 25 known staphylococcal enterotoxins. Some variants present unique and even host-specific features. Here, we review the role of SEC in human...

Over the years the growth and health of food-producing animals have been enhanced by the use of antibiotics. These have helped reduce on-farm mortalities, lower incidences of diseases and more importantly improve productivity. Generally, the utilization of antibiotics in feed has been reevaluated since bacterial pathogens have established and shared a variety of antibiotic resistance mechanisms...

In the last years, multidimensional liquid chromatography technique became very widespread for the complete separation of non‐volatile analytes in complex matrices. The main advantage of these techniques, especially when coupled with mass spectrometry, is the enhancement of separation power or peak capacity, due to an increase in selectivity and sensitivity of the two systems. With respect to...

Hepatitis C is a liver disease caused by the hepatitis C virus (HCV). The treatment of HCV infection has become more complicated due to various genotypes and subtypes of HCV. Treatment of HCV has made significant advances with direct‐acting antivirals. However, for the choice of medicine or the combination of drugs for hepatitis C, it is imperative to detect and discriminate the crucial HCV...

Shiga‐toxigenic Escherichia coli (STEC) is a major bacterium responsible for disease resulting from foodborne infection, including bloody diarrhea and hemolytic uremic syndrome (HUS). STEC produces important virulence factors such as Shiga toxin (Stx) 1 and/or 2. In the STEC family, some Locus for Enterocyte Effacement (LEE)‐negative STEC produce two different types of cytotoxins, Stx2 and...
