Abstract There are several reports on the detection of Listeria monocytogenes in Iran, which has been identified as a major public health problem. In addition, due to drug resistance and strong biofilm formation of this pathogen, new approaches such as using probiotics are needed to combat this bacterium. The aim of this study was to investigate the effect of spore-forming probiotics on the expression of virulence genes hly, plc, inlA, and invasion of L. monocytogenes. Spore-forming probiotics were co-cultured with L. monocytogenes at different time points and following cell count, the expression level of virulenc...

ConclusionListeria is difficult to isolate and it is not susceptible to first-line treatment for bacterial meningitis with extended-spectrum cephalosporins. Early recognition is therefore crucial for a positive outcome. Pediatricians have to perform close clinical monitoring of these children and be aware of possible complications.A review of all cases of Listeria meningitis complicated by hydrocephalus in healthy children has been performed, to provide an overview on clinical features, treatment options and outcome.

Listeriosis is a severe food-borne infection caused by the Gram-positive rod, Listeria monocytogenes. Despite the low incidence (3 –8 cases per million), Listeriosis has a case fatality rate of 20–30% as it occurs...

Surface water used for produce production is a potential source of pre-harvest contamination with foodborne pathogens. Decisions on how to mitigate food safety risks associated with pre-harvest water use currently rely on generic Escherichia coli-based water quality tests, although multiple studies have suggested that E. coli levels are not a suitable indicator of the food safety risks under all relevant environmental conditions. Hence, improved understanding of spatiotemporal variability in surface water microbiota composition is needed to facilitate identification of alternative or supplementary indicators that co-occur ...

This article includes detailed instructions for use of either foodborne or i.v. inoculation of mice and discusses the rationale for choosing either model. Additionally, a protocol is provided for enrichment of neutrophils and monocytes from the infected liver in a manner that allows for determination of bacterial burden while still providing sufficient cells for use in flow cytometric analysis or in vitro assays. © 2020 Wiley Periodicals LLC.

There is grave necessity to counter the menace of drug-resistant biofilms of pathogens using nanomaterials. Moreover, we need to produce nanoparticles (NPs) using inexpensive clean biological approaches that demonstrate broad-spectrum inhibition of microbial biofilms and cytotoxicity against HepG2 cell lines. In the current research work, titanium dioxide (TiO2) NPs were fabricated through an environmentally friendly green process using the root extract of Withania somnifera as the stabilizing and reducing agent to examine its antibiofilm and anticancer potential. Further, X-ray diffraction (XRD), Fourier transform infrare...
