Profiles of Burkholderia pseudomallei persistence and antibodies in blood, spleen, liver, and lungs of infected BALB/c mice were investigated. Animals were infected intraperitoneally with low (6 colony-forming units) or high (230 colony-forming units) doses of B. pseudomallei. In the high-dose infected group, bacteria were found by culture in 100% of blood, liver, spleen and lung samples at 24 and 48 hours after infections; blood samples were 100% positive by polymerase chain reaction after 60 hours. Antibody responses in the high-dose infected group were low. These responses were detected in the low-dose infected group after 5 days, peaked at 7–14 days, and showed persistence until 28 days post-infection. Bacterial loads and antibody profiles varied according to the level of bacterial infections. This kinetic study, although in animals, provides crucial knowledge that might be useful for the development of a sensitive and specific diagnostic assay for patients with melioidosis.
