Detecting and identifying the origins of foodborne pathogen outbreaks is a challenging. The Next-Generation Sequencing (NGS) panel method offers a potential solution by enabling efficient screening and identification of various bacteria in one reaction.

The present study reports the production, extraction, partial characterization, biological activities and use in textile dyeing of an orange pigment from Metabacillus idriensis strain LipT27 (MN818522.2). Pigment production occurred with 400 µg carotenoid/g biomass yield. Characterization of the methanol extracts of pigment by UV–Visible spectrophotometry, TLC, NMR, and FTIR indicated that the pigment was a carotenoid group pigment.

In recent years, a number of bacterial detection methods have been developed to replace time-consuming culture methods. One interesting approach is to mobilize the ability of phage tail proteins to recognize and bind to bacterial hosts. In this paper, the authors provide an overview of the current methodologies in which phage proteins play major roles in detecting pathogenic bacteria.

The effects of sumac, cumin, black pepper and red pepper diethyl ether extracts on the growth of eight foodborne pathogens (FBP) and their biogenic amine (BA) production were investigated in histidine decarboxylase broth. The antimicrobial effect was determined by the minimum inhibitory (MIC) and minimum bactericidal (MBC) concentrations. Sumac extract showed the highest antimicrobial activity against FBP.

ABSTRACT The human pulmonary environment is complex, containing a matrix of cells, including fibroblasts, epithelial cells, interstitial macrophages, alveolar macrophages and neutrophils. When confronted with foreign material or invading pathogens, these cells mount a robust response. Nevertheless, many bacterial pathogens with an intracellular lifecycle stage exploit this environment for replication and survival.

Unraveling the trends of phage-host versus phage-phage coevolution is critical for avoiding possible undesirable outcomes from the use of phage preparations intended for therapeutic, food safety or environmental safety purposes. We aimed to investigate a phenomenon of intergeneric recombination and its trajectories across the natural populations of phages predominantly linked to foodborne pathogens.

The occurrence of multidrug-resistant pathogenic bacteria, such as methicillin-resistant Staphylococcus aureus (MRSA), multidrug-resistant Acinetobacter baumannii (MDRAB), extended-spectrum β-lactamase (ESBL) Escherichia coli, and Pseudomonas aeruginosa, has become a serious problem in animals and public.

Some biological activities of dihydroquercetin (DHQ), including antioxidative, antibacterial and anticancer activities, and the oxidative stability of butter oil supplemented with DHQ were evaluated. The DPPH* radical‐scavenging activity was high for DHQ, with an IC50 of 63.83 ± 3.11 μg/ml, compared to that of Trolox, which had an IC50 of 117.02 ± 5.19 μg/ml, over the concentrations studied (10–100 μg/ml).

Salmonella enterica, Listeria monocytogenes, Shigella flexneri, Escherichia coli O157:H7, Vibrio parahaemolyticus, Staphylococcus aureus, Vibrio cholerae, Clostridium botulinum type A, Bacillus cereus, Clostridium perfringens Alpha toxin, and Yersinia enterocolitica are 11 common foodborne pathogens. Traditional bacterial culture methods for detecting pathogens are time‐consuming and labor‐intensive.

Abstract

Wild animals can serve as hosts, amplifiers, or reservoirs for various zoonotic diseases. Most species of deer in highly fragmented agricultural landscapes, search out maximum cover from intrusive human activity. Hence, the likelihood of zoonosis transmission is likely to increase the more humans and wildlife interact.
