Unlabelled: Drug resistance remains a global threat, and the rising trend of consuming probiotic-containing foods, many of which harbor antibiotic resistant determinants, has raised serious health concerns. Currently, the lack of accessibility to location-, drug- and species-specific information of drug-resistant probiotics has hampered efforts to combat the global spread of drug resistance. Here, we describe the development of ProbResist, which is a manually curated online database that catalogs reports of probiotic bacteria that have been experimentally proven to be resistant to antibiotics. ProbResist allows users to search for information of drug resistance in probiotics by querying with the names of the bacteria, antibiotic or location. Retrieved results are presented in a downloadable table format containing the names of the antibiotic, probiotic species, resistant determinants, region where the study was conducted and digital article identifiers (PubMed Identifier and Digital Object Identifier) hyperlinked to the original sources. The webserver also presents a simple analysis of information stored in the database. Given the increasing reports of drug-resistant probiotics, an exclusive database is necessary to catalog them in one platform. It will enable medical practitioners and experts involved in policy making to access this information quickly and conveniently, thus contributing toward the broader goal of combating drug resistance.

The lack of precise, real-time analytical tools for monitoring tumor microenvironment changes during treatment hinders advancements in integrated diagnostic and therapeutic platforms. Traditional caspase-3 monitoring strategies are limited by their inability to address drug resistance and newly discovered apoptotic pathways, leading to reduced accuracy and practicality. To overcome these limitations, we developed a fluorescence-based "Trojan horse" nanosystem, PFpR@CM, featuring high-sensitivity Caspase-1 detection, tumor-targeted delivery, and photothermal therapy.

The broth microdilution (BMD) test recommended for detecting colistin sensitivity is labor-intensive and difficult to perform under routine conditions. There is a need for alternative methods that produce fast and reliable results in routine laboratory studies.

This study aimed to determine the prevalence of oxacillinase resistance (OXA) genes in multidrug-resistant (MDR) Gram-negative bacteria.
Methods: One hundred and six clinical isolates were collected from a stock of Gram-negative isolates and were identified and tested for antibiotic susceptibility and presence of OXA genes using polymerase chain reaction (PCR).
Background: The purpose of the study was to understand the distribution and drug resistance characteristics of Enterococcus so as to provide a reliable basis for clinical use of antibiotics and hospital infection control.
Methods: In total, 3,455 strains of Enterococcus, isolated from January 2010 through December 2021, were col-lected. Bruker MALDI biotyper, MICROSCAN walkaway 40 analysis system, and Vitek-2 compact automatic drug sensitivity identification analyzer were used to identify the strains and to test drug sensitivity, and then the results were analyzed.

Introduction: Multi-drug resistance (MDR) is one of the leading reasons that cause the failures of cancer treatment. Novel agents that may reverse MDR and neutralize drug-resistant cancer cells are highly desirable for clinical practice. The targeting of cellular redox homeostasis and/or mitochondria-mediated energy metabolism are promising strategies for the suppression of drug-resistant cancer cells.
