Environmental has been postulated to be aerosolized during ploughing and heavy rain, and could result in inhalational melioidosis. Here, we determined the presence of in soil, paddy field water (PFW), air, and rainwater samples in a single rice paddy field in Ubon Ratchathani, northeast Thailand. In 2012, we collected 100 soil samples during the dry season, 10 PFW samples during the monsoon season, 77 air samples during ploughing ( = 31) and heavy rains ( = 46), and 60 rainwater samples during 12 rain events. We found that 32 soil samples (32%), six PFW samples (60%), and none of the air and rainwater samples were culture positive for . Other soil bacteria were isolated from air and rainwater samples. Mean quantitative count of estimated from two culture-positive PFW samples was 200 colony forming units/mL. Our findings suggest that the risk of melioidosis acquisition by inhalation in Thailand might be low.
据推测，环境中的在耕作和暴雨期间会被气溶胶化，可能导致吸入性类鼻疽。在此，我们测定了泰国东北部乌汶叻差他尼一个单一稻田土壤、稻田水（PFW）、空气和雨水样本中的存在情况。2012年，我们在旱季采集了100份土壤样本，在季风季节采集了10份PFW样本，在耕作（n = 31）和暴雨（n = 46）期间采集了77份空气样本，以及在12次降雨事件期间采集了60份雨水样本。我们发现32份土壤样本（32%）、6份PFW样本（60%）对呈培养阳性，而空气和雨水样本均未培养出阳性。从空气和雨水样本中分离出了其他土壤细菌。从两份培养阳性的PFW样本估计的平均定量计数为200菌落形成单位/毫升。我们的研究结果表明，在泰国通过吸入感染类鼻疽的风险可能较低。
