Abstract

Antibiotic resistance, a significant public health hazard, is predicted to cause 10 million deaths worldwide by 2050. The study aimed to identify culturable bioaerosols in the indoor air of dental units in Lahore and assess their antibiotic resistance. Air samples were collected from 10 dental unit locations at different distances, with average concentrations of fungi and bacteria falling within intermediate ranges, per the Global Index of Microbial Contamination (GIMC/m3) index. The study found higher antibiotic-resistant strains in hospital dental units, particularly during winter. The most vigorous strain, S.aureus-NAJIH18, exhibited 70% resistance to ceftazidime. The research highlights the importance of quantifying microbial pollutants for evaluating their source and complexity. It suggests proactive mitigation techniques, such as focused cleaning and air filtration, to improve indoor air quality can mitigate the spread of antibiotic-resistant strains. These insights offer hope in combating the growing public health threat of antibiotic resistance.

室内生物气溶胶的时间趋势：对牙科保健环境的影响。

抗生素耐药性是一个重大的公共卫生隐患，预计到 2050 年将导致全球 1000 万人死亡。这项研究旨在确定拉合尔牙科诊所室内空气中可培养的生物气溶胶，并评估其抗生素耐药性。研究人员从不同距离的 10 个牙科诊所收集了空气样本，根据全球微生物污染指数（GIMC/m3），真菌和细菌的平均浓度处于中等水平。研究发现，医院牙科单位的抗生素耐药菌株较高，尤其是在冬季。最活跃的菌株金黄色葡萄球菌-NAJIH18 对头孢他啶的耐药性高达 70%。这项研究强调了量化微生物污染物对评估其来源和复杂性的重要性。研究表明，通过集中清洁和空气过滤等积极的缓解技术来改善室内空气质量，可以减少抗生素耐药菌株的传播。这些见解为应对抗生素耐药性这一日益严重的公共卫生威胁带来了希望。

期刊介绍： International Journal of Environmental Health Research ( IJEHR ) is devoted to the rapid publication of research in environmental health, acting as a link between the diverse research communities and practitioners in environmental health. Published articles encompass original research papers, technical notes and review articles. IJEHR publishes articles on all aspects of the interaction between the environment and human health. This interaction can broadly be divided into three areas: the natural environment and health – health implications and monitoring of air, water and soil pollutants and pollution and health improvements and air, water and soil quality standards; the built environment and health – occupational health and safety, exposure limits, monitoring and control of pollutants in the workplace, and standards of health; and communicable diseases – disease spread, control and prevention, food hygiene and control, and health aspects of rodents and insects. IJEHR is published in association with the International Federation of Environmental Health and includes news from the Federation of international meetings, courses and environmental health issues.
