Journal of Food Safety, EarlyView. India is the largest producer and exporter of buffalo (Bubalus bubalis) meat in the world. But there are restrictions on the slaughter of cattle (Bos indicus/Bos taurus) and export of beef (cattle meat) from the country. This led to the incidences of misrepresentation of beef and other low cost meat as buffalo meat during export and hence necessitates reliable techniques for species authentication of buffalo meat.

Letters in Applied Microbiology, Accepted Article. In this study we investigated the incidence of Listeria monocytogenes in the receiving meat, the meat products, the personnel and the environment of a vertically integrated company in Northern Greece owing a processing plant and three trading facilities.

Journal of Applied Microbiology, Accepted Article. Aims
The aim of the study was to develop a microarray-based method for the detection of antibiotic-resistant Campylobacter in broiler farms to decrease the risk of contamination of chicken meat.

Colistin and tigecycline are the last options against carbapenem-resistant hypervirulent Klebsiella pneumoniae (CR-hvKP). Intersecting resistance determinants have been detected between these antibiotics; however, there is only limited evidence of such association.

ABSTRACT High Temperature Requirement A (HtrA) was identified as a secreted virulence factor in many pathogenic bacteria, including Listeria monocytogenes. Recently, it was discovered that Helicobacter pylori and Campylobacter jejuni HtrAs can directly cleave the human cell-adhesion molecule E-cadherin, which facilitates bacterial transmigration. HtrAs also interact with extracellular matrix (ECM) molecules.

Background Klebsiella pneumoniae is a critically important pathogen in the Philippines. Isolates are commonly resistant to at least 2 classes of antibiotics, yet mechanisms and spread of its resistance are not well studied. Methods A retrospective sequencing survey was performed on carbapenem-, extended spectrum beta-lactam-, and cephalosporin-resistant Klebsiella pneumoniae isolated at 20 antimicrobial resistance (AMR) surveillance sentinel sites from 2015 through 2017.

Background Klebsiella species, including the notable pathogen K. pneumoniae, are increasingly associated with antimicrobial resistance (AMR). Genome-based surveillance can inform interventions aimed at controlling AMR. However, its widespread implementation requires tools to streamline bioinformatic analyses and public health reporting.

Background Klebsiella pneumoniae is a World Health Organization high-priority antibiotic-resistant pathogen. However, little is known about Klebsiella lineages circulating in Nigeria. Methods We performed whole-genome sequencing (WGS) of 141 Klebsiella isolated between 2016 and 2018 from clinical specimens at 3 antimicrobial-resistance (AMR) sentinel surveillance tertiary hospitals in southwestern Nigeria.

Phages are strong antibacterial agents commonly used in the food industry, especially phage cocktails that cause much stronger and more stable effects. This study aimed to identify and characterize three absolutely lytic phages of E. coli isolated from poultry farms.

Ringer tablet-based micelle-mediated extraction-solvent back extraction method coupled to HPLC has been investigated for the determination of neonicotinoid pesticides in honey, cucumber, and orange samples. The method employs the entrapment of the analytes in the micelles of non-ionic surfactant (Triton X-114). By ultrasonication, the ringer tablet is dissolved, and the extractant is released into the aqueous phase as very tiny droplets to provide a cloudy solution.

Abstract

Difenoconazole (DIF) and dimethomorph (DIM) are widely used pesticides frequently detected together in environmental samples, so the deleterious effects of combined exposure warrant detailed examination. In this study, the individual and combined effects of DIM and DIF on conventional developmental parameters (hatching rate, deformity rate, lethality) and gene expression were measured in embryonic zebrafish.

Fungal contamination of food, especially by mycotoxigenic fungi, not only reduces the quality of the food, but can also cause serious diseases, thus posing a major food safety challenge to humans. Apart from sound food control systems, there is also a continual need to explore antifungal agents that can inhibit fungal growth and mycotoxin production in food. Many types of fatty acids (FAs) and their oxidized derivatives, oxylipins, have been found to exhibit such effects.

Journal of Food Safety, EarlyView. The aim of the present study was to investigate the antimicrobial mechanism of oregano essential oil (OEO) against Shewanella putrefaciens. Antimicrobial activity of OEO against Shewanella putrefaciens was investigated by the agar disc diffusion method. The change of growth curve, electric conductivity, the integrity of cell membrane, alkaline phosphatase (AKP), and lactate dehydrogenase (LDH) activity were measured to evaluate its antibacterial mechanism.

Staphylococcus aureus (S. aureus) is now regarded as a zoonotic agent. Methicillin-susceptible S. aureus (MSSA) ST398 is a livestock-associated bacterium that is most prevalent in China, but there are currently no data available for Shandong. Therefore, the aim of this study was to investigate the epidemiology and characterization of MSSA ST398 from retail pork and bulk tank milk (BTM) in Shandong. A total of 67 S.

Finafloxacin is a novel fluoroquinolone with optimal antibacterial activity in low pH environments, therefore offering a therapeutic advantage over some traditional antibiotics, in treating bacterial infections associated with acidic foci. Coxiella burnetii, the causative agent of Q fever, is a bacterium which resides and replicates in acidic intracellular parasitic vacuoles.

Many recent pandemics have been recognized as zoonotic viral diseases. While their origins remain frequently unknown, environmental contamination may play an important role in emergence. Thus, being able to describe the viral diversity in environmental samples contributes to understand the key issues in zoonotic transmission.

Urbanization causes alteration in atmospheric, soil, and hydrological factors and substantially affects a range of morphological and physiological plant traits. Correspondingly, plants might adopt different strategies to adapt to urbanization promotion or pressure. Understanding of plant traits responding to urbanization will reveal the capacity of plant adaptation and optimize the choice of plant species in urbanization green.
