| Abstract: | A case of acute meningoencephalomyelitis caused by infection with Pseudomonas pseudomallei is described. Clinically there was inability to stand, opisthotonus, facial paralysis and nystagmus, rapidly progressing to violent struggling.
Gross examination revealed malacia and haemorrhage in the medulla oblongata and adjacent spinal cord. Microscopically there were disseminated focal neutrophilic accumulations in affected areas, perivascular cuffing with mononuclear cells and lymphocytes and marked oedema. Intracellular bacteria were identified in sections stained by the Giemsa method. |
