- 1Describe microscopic appearance of BurkholderiaGram -
Medium sized Rods
Motile with one or more bipolar flagella(not B.mallei)
DOES not produce any pigments - 2What are its optimal growth conditions?Aerobic conditions
No special requirements
Grow well on MacConkey agar
!B.mallei!needs glycerol in medium to grow - 3Catalase and Oxidase test resultsBoth positive
- 4What are the virulent mechanisms of B.mallei?+A capsule and type III and type IV secretion systems
+A quorum antigenic variation system
Capable of intracellular survival/spread can utilize actin based motility
=Its presence causes a hypersensitivity reaction(crucial for its reaction) - 5What does the acute form of Glanders disease cause?Forms yellow or grey nodules and ulcers in the respiratory tract or the skin.
Its acute septicemic form
->Fever,mucopurulent nasal discharge and respiratory signs

- 8Manifestation of Farcy diseaseA lymphangitis
->where nodules start to develop through lymphatic vessels of the limbs
->Ulcers later on develop and release a yellowish pus - 9Is Glanders treatable?Yes,but there is always the possibility of atb resistance
(Chronically affected animals may survive for months or may recover and shed through the respiratory tract or skin) - 10Which form of the disease can show regional lymphadenopathy?Nasal form:With ulcerative nodules on the mucosa of the nasal septum and lower part of the turbines
- 11The ulcers in the nasal form when they heal leave____________Star shaped scars
- 12How do lungs alter through Glanders?Develop tubercule-like lesions
- 13Which species causes Melioidosis?Burkholderia pseudomallei
- 14i)Second name for Melioidosis and ii)pathogenetic manifestationi)Pseudoglanders
