Airborne Staphylococcus aureus Exposure Induces Depression-like Behaviors in Mice via Abnormal Neural Oscillation and Mitochondrial Dysfunction

Environmental Science & Technology, Год журнала: 2025, Номер 59(2), С. 1133 - 1144

Опубликована: Янв. 7, 2025

Airborne Staphylococcus aureus exists widely in the natural environment and is closely related to human health. Growing evidence indicates that environmental air pollution elevates risk of depressive disorders. However, potential role airborne S. development depression remains unclear. This study aims elucidate neurotoxic effects mechanisms associated with caused by aureus. Mice were randomly divided into four groups, experimental groups at 4.89 × 102, 8.89 105, 1.27 108 CFU/m3 during consecutive weeks. exposure contributed depression-like behaviors mice, especially high-concentration group. The electroencephalography signal analysis identified uncoupling theta gamma bands a shift beta rhythm toward delta oscillation medial prefrontal cortex mice. Neuropathological showed uplifted neuroinflammation elevated levels oxidative stress brain. Neuroinflammation resulted mitochondrial dysfunction, which could lead apoptosis. Together, this provides strong basis for understanding adverse outcomes on mental health

The corridor effect in droplet and aerosol pathogens transmission

Physics of Fluids, Год журнала: 2025, Номер 37(3)

Опубликована: Март 1, 2025

This study investigates the effect of natural ventilation on distribution airborne pathogens in narrow, low-ceiling corridors typical hotels, offices, or cruise ships. Two scenarios are examined: a milder cough at 6 m/s and stronger 12 m/s. A reference baseline case with no airflow is compared to cases featuring an incoming velocity 1 (3.6 km/h), examining differences dispersal respiratory droplets from two individuals coughing spaced 5 meters apart. Both direction airflow, assuming one-way traffic minimize pathogen transmission. Findings indicate that accelerates past door, exceeding 3 m/s, gusts reaching 4 due interaction recirculation zones. acceleration affects droplet dispersal. Larger (>150 μm) maintain ballistic trajectory, traveling 2–4 m, potentially increasing transmission risk but suggesting 5-m distancing policy could suffice for protection. Smaller (<150 μm), especially those <100μm, spread extensively regardless strength while containing most viral mass overall. Thus, alone insufficient. The recommends additional safety measures be enforced, such as wearing masks, stricter usage protocols by limiting corridor use one person every 20–30 s, eliminating when feasible effectively mitigate risks environments.

Emission Dynamics and Public Health Implications of Airborne Pathogens and Antimicrobial Resistance from Urban Waste Collection Facilities

Environmental Science & Technology, Год журнала: 2025, Номер unknown

Опубликована: Апрель 14, 2025

Airborne pathogens and antimicrobial resistance (AMR) present significant global health threats. Household waste collection facilities (WCFs), crucial initial nodes in urban management systems, have been understudied regards to their role emitting these hazards. This study investigated the abundance, composition, sources, driving mechanisms, risks associated with AMR originating from WCFs a major city, using culture-based analysis, high-throughput sequencing, risk modeling, respectively. The atmospheric escape rates of culturable bacteria (43.4%), fungi (71.7%), antibiotic-resistant (ARB) (43.7%) were estimated based on concentration differences between interior exterior by SourceTracker2 analysis. Health assessments showed that annual infection for waste-handling workers ranged 0.194 0.489, far exceeding World Organization's acceptable limit 10-4. Community exposure notable up 220 m downwind WCFs, marking maximum extent pathogen dispersion. Our analysis suggests approximately 6.3% megacity's area (equivalent 400 km2) is within potential zones influenced WCF emissions. These results underscore critical need evaluate mitigate public posed airborne emitted megacities globally.
