Isolation and culture of Burkholderia pseudomallei remains the main stay in the diagnosis of melioidosis. Thus, the search for selective and differential media for B. pseudomallei has been ongoing. A number of such media have been reported with varying efficacy. Ashdown medium is the most established selective medium for the isolation of B. pseudomallei. There are no reports of differential media differentiating B. pseudomallei from Burkholderia cepacia. This report documents such a selective and differentiating medium for B. pseudomallei. Of a total of 1042 clinical specimens containing mixed flora and gram-negative isolates that were tested on this medium, 16 of the specimens yielded B. pseudomallei. The isolation rate was found to be 1.5%. This medium was found to be simple and inexpensive, can be made by small laboratories, and called as Francis medium. Based on the colony morphology and color, a preliminary report can be made within 18-24 h for the presence of B. pseudomallei. Our study showed that this medium had an overall sensitivity of 78.4% with a specificity of 92.2%. The use of this medium as an early diagnostic tool will help to reduce mortality and morbidity of melioidosis patients.

D003470 Culture Media Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN. Media, Culture

D012680 Sensitivity and Specificity Binary classification measures to assess test results. Sensitivity or recall rate is the proportion of true positives. Specificity is the probability of correctly determining the absence of a condition. (From Last, Dictionary of Epidemiology, 2d ed) Specificity,Sensitivity,Specificity and Sensitivity
D016957 Burkholderia pseudomallei A species of gram-negative, aerobic bacteria that causes MELIOIDOSIS. It has been isolated from soil and water in tropical regions, particularly Southeast Asia. Pseudomonas pseudomallei
