Abstract

Over past few years, people are giving more attention to air pollution and its effects on human health. Due to the high population density in Bangladesh, air pollution is a major issue in metropolitan areas, especially in Dhaka city. Present study aims to isolate air-borne microbes from the inside environment of public transport and different types of microbes that are frequently encountered by commuters when they touch the interior surfaces of vehicles used for public transport in Dhaka City. Atmospheric load of microorganisms was measured with petri dish which was kept open for 30 minutes in the sampling locations and swabs were taken from interior surfaces of vehicles. Air samples collected from both bus and railway stations showed a high atmospheric microbial count (total viable bacteria and total fungal count were 140 to 776 CFU/plate/30 min and 27 to 168 CFU/plate/30 min, respectively). A similar outcome was found after analysis of swab samples of the contact surfaces of the vehicles as well. A total of four bacterial pathogens were identified from the interior surfaces of the vehicle including Escherichia coli, Bacillus spp., Pseudomonas spp. and Vibrio spp. which are known to be associated with gastrointestinal tract infection. To manage and control the environmental health risks caused by air pathogens, an authorized governmental agency should do continuous monitoring of air quality to reduce the negative effects and impacts of air pathogens on human and animal health. This research has shown a great concern to health practitioners in developing countries because these are pathogens that are mostly resistant to the commonly available antibiotics used in the treatment of infection associated with these pathogens. Most importantly, we need to raise awareness among the public in order to reduce the load and spread of pathogenic bacteria in the environment. Stamford Journal of Microbiology, Vol.11 (1) 2021: 7-10

公共交通工具空气和接触表面微生物监测及其与人感染风险的相关性
在过去的几年里,人们越来越关注空气污染及其对人体健康的影响。由于孟加拉国人口密度高,空气污染是大都市地区的一个主要问题,特别是在达卡市。本研究旨在分离公共交通工具内部环境中的空气传播微生物,以及达喀市通勤者接触公共交通工具内部表面时经常遇到的不同类型的微生物。用培养皿在采样地点开放30分钟,测量微生物的大气负荷,并从车辆内部表面取拭子。公交车站和火车站采集的空气样本均显示较高的大气微生物计数(活菌总数为140 ~ 776 CFU/平板/30 min,真菌总数为27 ~ 168 CFU/平板/30 min)。在对车辆接触面的棉签样本进行分析后,也发现了类似的结果。从车辆内表面共鉴定出4种已知与胃肠道感染相关的细菌病原体,包括大肠杆菌、芽孢杆菌、假单胞菌和弧菌。为了管理和控制空气病原体造成的环境健康风险,授权的政府机构应持续监测空气质量,以减少空气病原体对人类和动物健康的负面影响和影响。这项研究引起了发展中国家卫生从业人员的极大关注,因为这些病原体大多对用于治疗与这些病原体相关的感染的常用抗生素具有耐药性。最重要的是,我们需要提高公众的认识,以减少环境中致病菌的负荷和传播。微生物学报,Vol.11 (1) 2021: 7-10
