| + | ==Overview== |
| + | ''Burkholderia pseudomallei'' is a species of the ''[[Burkholderia species - Overview|Burkholderia]]'' genus. ''B.pseudomallei'' causes melioidosis, an opportunistic infection which is endemic in Asia and Australia. It primarily infects rodents. |
| + | |
| + | ==Pathogenesis== |
| + | Infection occurs via ingestion, inhalation or via skin wounds from the environment. The bacteria contains an exotoxin, dermonecrotic protease and lecithinase which is implicated in pathogenicity. Strain virulence and host immunosuppression is important. ''Burkholderia pseudomallei'' is also motile, by polar flagellae. |
| + | |
| + | ==Diagnosis== |
| + | Diagnosis of the ''B.pseudomallei'' bacteria can be made via specimens, including; pus from abscesses, affected tissues and blood. |
| + | The fluorescent antibody technique can be done on tissue smears. ''B.pseudomallei'' grows on blood agar and MacConkey agar plates, incubated aerobically. The colonies have a musty smell and you see lactose fermentation on MacConkey. Slide agglutination, ELISA, complement fixation and indirect haemagglutination tests for serum antibodies are also all diagnostic of ''B.pseudomallei.'' |
