Bacterial-mediated cancer therapy (BMCT) has become a hot topic in the area of antitumor treatment. Salmonella has been recommended to specifically colonize and proliferate inside tumors and even inhibit tumor growth. Salmonella typhimurium (S. typhimurium) is one of the most promising mediators, which can be easily manipulated. S. typhimurium has been engineered and designed as cancer-targeting therapeutics, and can be improved by combining with other therapeutic methods, e.g. chemotherapy and radiotherapy, which regulate the tumor microenvironment synergistically. In view of all these strengths, the engineered attenuated...

Typhimurium) is an important intracellular pathogen, causing gastroenteritis or severe systemic infection in a variety of hosts. During infection, S. Typhimurium must survive and replicate in host macrophages, which produce abundant oxidative compounds. SoxRS regulon is a well-known regulator that is activated in response to oxidative stress and promotes bacterial tolerance to o...

(European Centre for Disease Prevention and Control (ECDC)) Nearly one in three foodborne outbreaks in the EU in 2018 were caused by Salmonella. This is one of the main findings of the annual report on trends and sources of zoonoses published by the European Food Safety Authority (EFSA) and the European Centre for Disease Prevention and Control (ECDC). West Nile virus and STEC infections were reported at unusually high levels.

Many Gram-negative bacteria use type III secretion systems (T3SSs) to inject virulence effector proteins into eukaryotic cells. The T3SS apparatus (T3SA) is structurally conserved among diverse bacterial pathogens and consists of a cytoplasmic sorting platform, an envelope-spanning basal body, and an extracellular needle with tip complex. The sorting platform is essential for effector recognition and powering secretion. Studies using bacterial “minicells” have revealed an unprecedented level of structural detail of the sorting platform; however, many of the structure-function relationships within this complex r...

This study evaluated the efficacy of low-energy X-ray with cut-off energy of 150 KeV to inactivate two of the most prevalent foodborne pathogens in dry edible bird's nest (EBN). The X-ray irradiation at 350 and 400 Gy decreased E. coli O157:H7 and S. Typhimurium from 6.35 ± 0.56 and 5.84 ± 0.67 log CFU/g, respectively, to undetectable level. The low-energy X-ray irradiation yielded the tR1 value of 37.6 ± 6.9 and the D10 value of 83.3 ± 7.0 Gy for E. coli O157:H7 and S. Typhimurium, respectively, which indicates that S. Typhimurium exhibited...

Authors: Abraham A, Ifeanyi SS, Muinah F, Ibidunni Oreoluwa BS, Coulibaly KJ, Adeyemi AI Abstract Infections caused by non-typhoidal Salmonella (NTS) are common around the world, with high morbidity and mortality rates recorded annually. Salmonella serovars harbor plasmids of various sizes which may play roles in antibiotic resistance and virulence. The aim of this study was to profile and determine the role of plasmids in ciprofloxacin resistance and virulence of Salmonella serovars. Using alkaline lysis method 25 NTS serovars from food animals and humans were assayed for plasmids. Isolates ability to resist healt...
