Association between Land Surface Temperature and Distribution of Burkholderia pseudomallei bacteria in Paddy Soil Using Landsat 8 Satellite Image

Burkholderia pseudomallei bacteria is found in soil and it is cause of melioidosis which is a problem in Public Health. This study aimed to create a distribution map of B. pseudomallei and analyze association between the presences of B. pseudomallei with land surface temperature. The classification of paddy field was performed using Landsat 8 satellite image. Seventy-eight soil samples were collected in paddy field, while soil temperatures were detected by Handheld Measuring Instruments. The sample sites were geo-referenced by Global Positioning System (GPS). Subsequently, the land surface temperature was estimated calibration by Ordinary Co-Kriging between Landsat 8 satellite images and soil temperature field survey. The statistical association between the presences of B. pseudomallei with land surface temperature was analyzed by Mann-Whitney U Test. The Results showed that 32 sites were positive of B. pseudomallei . The land surface temperature showed that maximum and minimum were 36.73 and 29.67 degree Celsius, respectively. The presences of B. pseudomallei were not significantly associated with land surface temperature (p-value 0.699). Keywords : B. pseudomallei ; Land surface temperature ; Landsat 8 satellite images
