Listeria infection inhibits IgE production in regional lymph nodes by suppressing the chemotaxis of basophils to lymph nodes
Abstract
Infection with Listeria induces a dominant shift to the Th1 immune response and inhibits the Th2 response. Papain is frequently utilized in animal models of allergies. Papain administration induces the chemotaxis of basophils to regional lymph nodes (LNs) and the production of interleukin (IL)‐4 by basophils, resulting in a Th2‐dominant status and increased IgE production in LNs. In this model, the production of IgE by LN cells is primarily controlled by IL‐4 produced by basophils. Based on this model, we hypothesized that Lm infection suppresses the IgE production by LN cells. Therefore, we investigated the...

ABSTRACT
Infection with Listeria induces a dominant shift to the Th1 immune response and inhibits the Th2 response. Papain is frequently utilized in animal models of allergies. Papain administration induces chemotaxis of basophils to regional lymph nodes (LNs) and production of interleukin (IL)‐4 by basophils, resulting in a Th2‐dominant status and increased IgE production in LNs. In this model, production of immunoglobulin (Ig) E by LN cells is primarily controlled by IL‐4 produced by basophils. Based on this model, it was postulated that Listeria monocytogenes (Lm) infection suppresses IgE production by LN cells. T...

Fosfomycin in the pediatric setting: Evidence and potential indications.
Abstract
To date, there has been little experience in using fosfomycin in children. However, its broad spectrum of action and excellent safety profile have renewed interest in this antibiotic, especially for treating infections by multidrug-resistant bacteria. The main indication for fosfomycin in pediatrics is currently community-acquired lower urinary tract infection. Given its good activity against bacteria, fosfomycin can also be useful in urinary infections caused by extended-spectrum beta-lactamase-producing enterobacteria. Fosfomycin presents very good dissemination to tissues including bone and is therefor...

Relevant safety aspects of raw milk for dairy foods processing
Adv Food Nutr Res. 2022;100:211-264. doi: 10.1016/bs.afnr.2022.01.001. Epub 2022 May 24.ABSTRACTThe concern with food safety in the milk chain begins with the quality of the raw milk. Due to the health hazard that this food can carry when contaminated, the focus of studies has turned to microbiological and chemical contaminants that may be present in raw milk. There is an essential concern about conventional pathogens (Shiga toxin-producing Escherichia coli, Salmonella spp., Listeria monocytogenes, Campylobacter spp., Salmonella spp., and coagulase-positive Staphylococcus spp.) and emerging pathogens (Arcobacter butzleri, ...
