Summary: The study reveals that LA-MRSA is present in the air of pig farms, but at low levels above 50 meters, and the proportion of MRSA-positive soil samples decreases with increasing distance from the farm building. Among individuals working outside the pig farm for a whole day, only one individual's nasal sample tested positive for LA-MRSA, indicating that airborne spread of MRSA from pig farms may not be a significant route for human contamination in such cases.

Summary: Influenza A viruses, including H9 subtype, can be transmitted from avian species to mammals, posing a pandemic concern. The ability of H9N2 viruses to transmit via aerosol in mammalian species is associated with minimal amino acid changes in the HA segment and combinations of surface genes with internal genes of human influenza viruses.

Summary: African swine fever (ASF) is a highly contagious and economically devastating disease in China's pig industry. This study provides the first evidence of aerosol transmission of ASFV under field conditions, highlighting the importance of studying aerosol transmission and developing strategies for creating low-risk environments for pig herds.

Summary: This paper provides a comprehensive review of the transmission characteristics, influential factors, and preventive strategies of common swine viral aerosols. It discusses the potential risks of long-distance transmission and short-distance transmission for different viruses. Various factors including aerosol particle sizes, viral strains, host sensitivity, weather conditions, and environmental conditions influence the transmission of viral aerosols. The paper proposes preventive and control strategies such as early warning models, viral aerosol detection, and air pretreatment.

Summary: The primary aim of this study was to assess the prevalence of fungi in selected hospital wards and evaluate the susceptibility of Aspergillus fumigatus isolates to triazoles. Air samples were collected and cultured on Sabouraud agar. The study found that protected rooms with sterile air circulation and air disinfection devices had significantly lower amounts of cultured fungi compared to unprotected rooms. The most contaminated areas were corridors and bathrooms, with Cladosporium and Penicillium being the dominant species. A rare outbreak of A. fumigatus spores was noted in a hospital for lung diseases but no triazole-resistant isolates were detected. Regular microbiological testing of the hospital environment can help detect spore outbreaks and enable corrective procedures.

Summary: Influenza A viruses have the ability to infect a wide range of bird and mammal species. They constantly evolve due to low proofreading activity and genomic reassortment, posing a threat to human and animal health. This study found that vaccination can reduce the likelihood of genomic reassortment and may influence the evolution of swine influenza viruses.

Summary: The COVID-19 pandemic has exposed critical knowledge gaps in our understanding of traditional respiratory virus transmission pathways, highlighting the need for updates. Improved understanding of aerosol transmission through studies of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection calls for a reassessment of major transmission pathways for other respiratory viruses, enabling better control measures to reduce airborne transmission.

Summary: The study demonstrates that vaccinating pigs against influenza can significantly reduce the risk of influenza virus transmission. Observations on pigs vaccinated with live-attenuated influenza virus or killed influenza virus, as well as corresponding ferret exposure groups, show improved outcomes on both sides of the interface. Pigs vaccinated with live-attenuated virus also show a significant delay in onset of infection among exposed ferrets.

Summary: We conducted a pilot study to investigate air quality in a California community with historically high PM2.5 levels. Combining computer-controlled scanning electron microscopy and continuous sensor data, we identified major PM types and their sources, providing valuable insights into community exposure assessment. The study findings suggest the effectiveness of air cleaners in reducing indoor PM concentrations.

Summary: This study demonstrates that direct sample introduction to ICPMS by laser ablation (LA-ICPMS) provides significant advantages in terms of simplifying sample preparation procedures and avoiding the generation of chemical waste. The research shows that LA-ICPMS can successfully be applied for the determination of the elemental composition of quartz fibre filter samples.

Summary: This study evaluated the genetic diversity of IAV in pigs at weaning in farms in the Midwestern USA. Multiple lineages of HA and NA were found to co-circulate in both piglets and farms, indicating significant genetic variability of IAV. The results underscore the need for novel strategies to prevent and control the spread of IAV within and between farms.
