Urban sanitation infrastructure is inadequate in many low-income countries, leading to the presence of highly concentrated, uncontained fecal waste streams densely populated areas. Combined with mechanisms aerosolization, airborne transport enteric microbes and their genetic material possible such settings but remains poorly characterized. We detected quantified pathogen-associated gene targets aerosol samples near open wastewater canals (OWCs) or impacted (receiving sewage wastewater)...
Antibiotic resistance (AR) determinants are enriched in animal manures, a significant portion of which is land-applied as soil amendment or fertilizer, leading to potential AR runoff and microbial pollution adjacent surface waters. To effectively inform monitoring mitigation efforts, thorough understanding description the persistence transport manure-derived flowing waters needed. We used experimental recirculating mesocosms assess water-column removal rates antibiotic genes (ARGs)...
Abstract In India, high rates of antibiotic consumption and poor sanitation infrastructure combine to pose a significant risk the public through environmental transmission antimicrobial resistance (AMR). The WHO has declared extended-spectrum beta-lactamase (ESBL)-positive Escherichia coli key indicator for surveillance AMR worldwide. current study, we measured prevalence bacteria in an urban aquatic environment India by detecting metabolically active ESBL-positive E. coli. Water samples...

Understanding the movement of antimicrobial resistance genes (ARGs) in environment is critical to managing their spread. To assess potential ARG transport through air via urban bioaerosols cities with poor sanitation, we quantified ARGs and a mobile integron (MI) ambient over periods spanning rainy dry seasons Kanpur, India (n = 53), where open wastewater canals (OWCs) are prevalent. Gene targets represented major antibiotic groups-tetracyclines (tetA), fluoroquinolines (qnrB), beta-lactams...
Abstract Lassa Fever, caused by virus (LASV), is endemic to West Africa, where approximately 300,000 illnesses and 5,000 deaths occur annually. LASV primarily spread infected multimammate rats via urine fomites, highlighting the importance of understanding environmental fate LASV. This study evaluated persistence strains on surfaces in aqueous solutions with sodium hypochlorite disinfection. (Josiah Sauerwald) were more stable DI water (k = 0.23 0.34 days -1 ) than primary influent...
Antimicrobial resistance (AMR) is a rapidly growing threat to human health, and wastewater treatment has also proven be hotspot for AMR selection dissemination the environment. Microbial source tracking (MST) targets potentially bridge existing gaps in monitoring during as indicators broad array of antibiotic genes (ARGs). In this study, we compared removal bacterial viral MST (E. coli, enterococci, somatic coliphage, adenovirus, polyomavirus, crAssphage, HF183/BacR287), ARGs (sul1, sul2,...
Lassa fever, caused by virus (LASV), is endemic to West Africa, where ≈300,000 illnesses and ≈5,000 deaths occur annually. LASV primarily spread infected multimammate rats via urine fomites, highlighting the need understand environmental fate of LASV. We evaluated persistence Josiah Sauerwald strains on surfaces, in aqueous solutions, with sodium hypochlorite disinfection. Tested were more stable deionized water (first-order rate constant [k] for Josiah, 0.23 days; Sauerwald, k = 0.34 days)...
