The aim of the experiment was to investigate the efficacy of a smectite-based clay binder (Toxo-MX) in reducing the toxicological effects of aflatoxin B1 (AFB1) in commercial broiler chickens. A total of 450 one-day old male broiler chickens were randomly allocated into three treatment groups with ten replicates of 15 birds each in a 42-day feeding experiment.

The current study investigated the fungal diversity in freshly harvested oat samples from the two largest production regions in Brazil, Paraná (PR) and Rio Grande do Sul (RS), focusing primarily on the Fusarium genus and the presence of type B trichothecenes. The majority of the isolates belonged to the Fusarium sambucinum species complex, and were identified as F. graminearum sensu stricto (s.s.), F. meridionale, and F. poae. In the RS region, F.

The aim of this study is to describe the features, the outcomes, and the clinical issues related to Remdesivir administration of a cohort of 220 patients (pts) with COVID-19 hospitalized throughout the last two pandemic waves in Italy. One hundred and nine pts were enrolled from 1 September 2020, to 28 February 2021 (Group A) and 111 from 1 March to 30 September 2021 (Group B). Notably, no differences were reported between the two groups neither in the timing of hospitalization.

Transboundary and Emerging Diseases, Accepted Article. Enteropathogenic parasites can infect a wide range of mammals, including humans, supposing an important zoonotic risk. Hepatitis E virus (HEV) is an emerging foodborne pathogen of increasing public health relevance, affecting both human and animal populations. Because both microorganisms share faecal-oral transmission route they may constitute an excellent model to evaluate the interplay between them.

Journal of Food Safety, EarlyView. Ultrafine bubble technology is a novel concept in food safety that can improve the potency of antimicrobials against biofilms. This study was conducted to evaluate the impact of gas (air, CO2, or N2) ultrafine bubbles incorporation in 100 and 200 ppm chlorine (Cl2) solutions to inactivate fresh Listeria monocytogenes biofilms on stainless steel.

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.
