Background: Acinetobacter baumannii is an opportunistic multidrugresistant, aerobic, glucose non-fermentative, and oxidative-negative coccobacilli bacteria. This life-threatening nosocomial infection is associated with immunocompromised patients.
Objective: This review aims to investigate the multiple drug resistance mechanisms and new emerging diagnostics & treatments for Acinetobacter baumannii.
Methods: All the articles that were most relevant to A. baumannii virulence and drug resistance mechanisms were founded by a literature search on PubMed. Google Patents were used to find discoveries related to diagnostics and treatment.
Results: Efflux pumps, β-lactamases, aminoglycosides, outer membrane proteins, and alteration of the target sites were identified in the Acinetobacter baumannii pathogen as the most prevalent drug resistance mechanisms. Gene detection, peptide detection, and antigen-antibody-associated detection were the latest diagnostics. Novel antimicrobial peptides, sterilization techniques using blue light, and combination therapies are being developed to effectively treat A. baumannii infections.
Conclusion: This review concludes that new drugs and formulations with high efficiency, low cytotoxicity, and no nephrotoxicity are in absolute need. In the near future, we can expect omics technology to play a significant role in discovering new drugs and potential targets.

High prevalence of reverse transcriptase inhibitors associated resistance mutations among people living with HIV on dolutegravir-based antiretroviral therapy in Francistown, Botswana.

Objectives: We assessed HIV-1 drug resistance profiles among people living with HIV (PLWH) with detectable viral load (VL) and on dolutegravir-based antiretroviral therapy (ART) in Botswana.
Methods: The study utilised available 100 residual HIV-1 VL samples from unique PLWH in Francistown who had viraemia at-least 6 months after initiating ART in Botswana's national ART program from November 2023 to January 2024. Viraemia was categorized as low-level viraemia (LLV) (VL: 200-999 copies/mL) or virologic failure (VF) (VL ≥1000 copies/mL).
Charge Regulation-Enhanced Type I Photosensitizer-Loaded Hydrogel Dressing for Hypoxic Bacterial Inhibition and Biofilm Elimination.

Biofilm-induced chronic bacterial infections represent a significant challenge in modern medicine due to their resistance to conventional antibiotic treatments. Although photodynamic therapy (PDT) has emerged as a promising antibiotic-free antibacterial strategy, the hypoxic condition within biofilms and the lack of an effective local drug delivery system have limited the clinical effectiveness of photosensitizer (PS) agents. Herein, we propose a type of charge regulation-enhanced type I PS-loaded hydrogel dressing for treating biofilm infection.

Previous studies have demonstrated that ac4C plays a pivotal role in viral infections. Despite numerous studies highlighting the strong correlation between ac4C modification and cancer progression, its detailed roles and molecular mechanisms in normal physiological processes and cancer progression remain incompletely understood.

Background: Leprosy is a chronic infectious disease caused by () However, the emergence of drug-resistant strains of this bacterium, especially multidrug-resistant (MDR) strains, is a serious concern. This study aimed to evaluate the global prevalence of MDR and its implications.
Methods: Using PRISMA guidelines, we systematically reviewed ISI Web of Science, MEDLINE, and EMBASE up to August 2023 to assess the prevalence of MDR .

Abortusequi ( Abortusequi) is the primary cause of abortions in equine animals, and can cause serious foodborne illness. Thus, effective biocontrol strategies are needed to decontaminate and control the emergence of foodborne diseases. In recent years, phages have been used as a new strategy for modulating foodborne pathogens and food safety.
