Recent interest in noninvasive diagnostic approaches has highlighted the potential of urinary microbiota as a novel biomarker for bladder cancer. This study investigated the urinary microbiota of 30 bladder cancer patients and 32 healthy controls using a specific NGS protocol that sequences eight hypervariable regions of the 16S rRNA gene, providing detailed insights into urinary microbiota composition. The relative abundance of microbial compositions in urine samples from cancer patients and healthy controls was analyzed across various taxonomic levels. No notable differences were highlighted at the phylum, class, order, and family levels. At the genus level, 53% of detected genera were represented in either cancer patients or healthy controls. Microbial diversity was significantly lower in cancer patients. The differential analysis identified five genera, Rhodanobacter, Cutibacterium, Alloscardovia, Moryella, and Anaeroglobus, that were significantly more abundant in cancer patients. Notably, Rhodanobacter was present in 20 cancer samples but absent in healthy controls. Conversely, 40 genera, including Lactobacillus, Propionibacterium, and Bifidobacterium, exhibited reduced abundance in cancer patients. These findings suggest that some genera may serve as potential biomarkers for bladder cancer, highlighting the need for further research to explore their roles in disease pathogenesis and their potential applications in diagnostics and therapeutics.

The Mpox (formerly monkeypox) outbreak in 2022 presented unprecedented challenges, including widespread transmission in non‐endemic regions, particularly among men who have sex with men. This study examines Mpox infections in Montpellier, France, focusing on diagnostic testing, serological profiles, and potential asymptomatic cases, based on data from Montpellier University Hospital. We retrospectively analyzed results from 91 patients tested positive for Mpox DNA. Antibody responses were monitored using novel Mpox virus peptide‐based serological assays. Our findings highlight that MPXV antibodies can develop early in infection, peaking within 2 weeks to 3 months, though responses varied by antigen type. Additionally, asymptomatic Mpox infections were suggested, with virus detected in blood, urine, anal, oral and genital swabs screened Sexual Transmitted Infection samples. Notably, viral presence was confirmed in Montpellier samples as early as mid‐May 2022, before the first known symptomatic case in Hospital, in the same period as the first official case in France. This study underscores the need for expanded screening in high‐risk clinics to control Mpox spread and supports the potential utility of serological assays for broad immune profiling. Enhanced diagnostic tools and proactive surveillance in sexual health settings are recommended to improve outbreak response and prevent further transmission.

The measles virus is highly contagious, and efforts to simplify its diagnosis are essential. A reverse transcriptase/recombinase polymerase amplification assay coupled with CRISPR/Cas12a and an immunochromatographic lateral flow detection (RT-RPA-CRISPR-LFD) was developed for the simple visual detection of measles virus. The assay was performed in less than 1 h at an optimal temperature of 42 °C. The detection limit of the assay was 31 copies of an RNA standard in the reaction tube. The diagnostic performances were evaluated on a panel of 27 measles virus RT-PCR-positive samples alongside 29 measles virus negative saliva samples. The sensitivity and specificity were 96% (95% CI, 81–99%) and 100% (95% CI, 88–100%), respectively, corresponding to an accuracy of 98% (95% CI, 94–100%; p < 0.0001). This method will open new perspectives in the development of the point-of-care testing diagnosis of measles.
