Recently, a unique method for bacterial transformation using nanofibers to inoculate DNA has been developed by Naoto Yoshida and colleagues. We have verified the principle, transforming Escherichia coli, Yersinia enterocolitica and Acinetobacter baumannii, and have established a user-friendly protocol. A buffered suspension of sepiolite-an inexpensive, fibrous yet inoffensive mineral-is mixed with bacteria and transforming DNA and the mixture directly spread on selective agar.

Objective: To compare the salivary profiles of smokers (e-cigarette smokers, e-cigarette and former conventional cigarette smokers, dual users, and conventional cigarette smokers) and non-smokers in adolescents, focusing on acidity level, flow rate, viscosity, as well as the quantity of Streptococcus mutans, Porphyromonas gingivalis, and Candida albicans.
Methods: This analytical observational study, with a cross-sectional design, involves collecting saliva samples from five groups through the draining method. Saliva viscosity was assessed visually, while saliva flow rate was monitored over a ten-minute period.

Background: The use of bacterial vaccines as a potential Bacterial-Based Cancer Therapy (BBCT) presents an innovative approach, transforming these vaccines into multifunctional tools capable of serving dual roles in medicine.
Materials And Methods: This study aimed to conduct in vitro, immunity-independent experiments to investigate the anticancer properties of vaccine-derived bacterial toxoids on various cancer cell lines. Six concentrations of the DTP vaccine (5 x 10-4, 25 x 10-5, 125 x 10-6, 625 x 10-7, 312 x 10-7, and 15 x 10-6 µg/ml) were tested on two cancer cell lines (SKG and HCAM) and a normal Rat Embryonic Fibroblast (REF) cell line.

Aim: We aimed to investigate the prevalence and factors associated with C-reactive protein (CRP) and procalcitonin (PCT) discordance in febrile infants with serious bacterial infections (SBIs).
Methods: We performed a retrospective review of febrile infants ≤ 90 days old presenting to the emergency department between December 2018 and June 2023. We compared conservative and pragmatic thresholds for PCT (< 0.

Microbial fuel cell (MFC) technology has received increased interest as a suitable approach for treating wastewater while producing electricity. However, there remains a lack of studies investigating the impact of inoculum type and hydraulic retention time (HRT) on the efficiency of MFCs in treating industrial saline wastewater. The effect of three different inocula (activated sludge from a fish-canning industry and two domestic wastewater treatment plants, WWTPs) on electrochemical and physicochemical parameters and the anodic microbiome of a two-chambered continuous-flow MFC was studied.

Background: Multidrug-resistant bacteria (MDR) represent a significant global health concern and vary in specific settings. Spain reported several annual deaths attributed to MDR bacteria, mainly carbapenemase-producing Enterobacterales.
Objectives: We aimed to characterise the incidence and temporal trends of MDR bacterial infections or colonisations reported within the province of Granada (data from five hospitals), and to investigate factors linked to clinical vulnerability.
