Abstract |
The distribution of Burkholderia pseudomallei in soil collected from four regions of |
Thailand and the frequency of B.pseudomallei infections in patients attending government |
hospitals throughout Thailand in 1997 were surveyed. A total of 3,585 soil samples collected |
from 896 sites in four regions of Thailand were cultured for B.pseudomallei using selective |
enrichment broth and modified Ashdown’s agar. The organism was recovered in 4.4%, 6.1%, |
20.4%, and 5.9% of the soil samples collected from the northern, central, northeastern, and |
southern regions, respectively, of Thailand (P<0.0001). Burkholderia pseudomallei was cultured |
from 50.1% of the sites in the northeastern region compared with 13.8%, 24.5%, and 18.4% in the |
northern, central, and southern regions, respectively (P<0.0001). The infection rate in patients |
attending government hospitals in the northeastern region (137.9 per 100,000 inpatients) was |
significantly higher than those in the northern (18 per 100,000 inpatients), central (13.4 per |
100,000 inpatients), and southern (14.4 per 100,000 inpatients) regions, respectively (P<0.0001). |
It is suggested that melioidosis, which is endemic in Thailand, is associated with the presence of |
. pseudomallei in soil. |
