Abstract Introduction Extended-spectrum β-lactamase-producing Escherichia coli (ESBL-Ec) and Klebsiella pneumoniae (ESBL-Kp) are among the leading cause of hospital-acquired infections globally. Fluoroquinolone-resistant ESBL-Ec ESBL-Kp have limited therapeutic options. This study investigated phenotypic genotypic characteristics plasmid-mediated quinolone resistance (PMQR) genes in circulating hospitalized patients, hospital environment, wastewaters Cameroon. Method A cross-sectional was conducted, from February to June 2024 two healthcare facilities Yaoundé, Clinical, inanimate surfaces wastewater samples were collected. Bacteria identification done using API20E kit. The ESBL phenotype detected double-disk synergy test on CHROMagar™ ESBL. Antimicrobial susceptibility testing performed disc diffusion method. Genes conferring β-lactams fluoroquinolones polymerase chain reaction (PCR). Clonal relatedness assessed enterobacterial repetitive intergenic consensus (ERIC)-PCR. Results overall prevalence across all sources 16% (103/652). 10% (49/495) 27% (38/141) environment 100% (16/16) wastewaters. Nearly (99.5%) multidrug-resistant. blaCTX−M most prevalent β-lactamase gene with ranging 74 85%. main aac-(6’)-Ib varying 57 70%. circulation between both three interfaces as well within evidenced. Conclusion Our results underscore crucial need implement real-time surveillance monitoring antimicrobial stewardship programs curb responsible neonatal sepsis neonatology unit Finally, genomic through One Health approach is needed fully understand transmission dynamics resistant bacteria

Unsafe hospital wastewater (HWW) is a significant concern, especially in low-and middle-income countries (LMICs) where the health impact often underreported. Socio-technical systems (STS) theory, which examines interplay between social and technical elements within complex systems, widely used developed but rarely applied LMIC hospitals. STS theory was employed to evaluate aspects of HWW treatment management Dhaka City, alongside comprehensive assessment WWT processes.

Structured observations assessed availability functionality selected The fieldworkers conducted 30 key-informant interviews across 13 hospitals, including 21 respondents from government nine private were cleaners, key professionals, public works department (PWD) engineers. We also analyzed relevant reports policies. Among hospitals surveyed, 10 had some form system, while remaining three lacked any infrastructure. Of those with WWT, seven utilized anaerobic baffled reactors septic tanks.

The public health issue of bacterial multi-resistance to antibiotics has gained awareness among the public, researchers, and pharmaceutical sector. Nevertheless, spread antimicrobial resistance been considerably aggravated by human activities, climate change, subsequent increased release antibiotics, drug-resistant bacteria, antibiotic genes in environment. extensive use for medical veterinary purposes not only induced increasing but also other problems, including negative effects on patient's microbiome. Preventive strategies, new treatment modalities, surveillance are progressively set up. A comprehensive approach is, however, lacking urgently tackling this adverse situation. To address challenge, we discussed here main causes driving pollution environment factors favorable emergence drug resistance. We next propose some key priorities research, prevention, surveillance, education supervise an effective clinical sustainable response.

The problem of antimicrobial resistance (AMR) is not limited to the medical field but also becoming prevalent on a global scale in environmental field. Environmental water pollution caused by discharge wastewater into aquatic environments has concern context sustainable development modern society. However, there have been few studies focused treatment hospital wastewater, and potential consequences this remain unknown. This study evaluated efficacy inactivation antimicrobial-resistant bacteria (AMRB) genes (AMRGs) model plant (WWTP) effluent based direct ultraviolet (UV) light irradiation provided conventional mercury lamp with peak wavelength 254 nm an light-emitting diode (UV-LED) emission 280 under test conditions which irradiance both was adjusted same intensity. overall results indicated that UV- UV-LED-mediated disinfection effectively inactivated AMRB types (>99.9% after 1-3 min UV 3 UV-LED treatment). Additionally, AMRGs were removed (0.2-1.4 log
