RESUMO
Primary Amoebic meningoencephalitis is a rare and fatal neuro-infection caused by free-living fresh-water amoeba Naegleria fowleri. It is a ubiquitous organism and the infection occurs usually via contact with warm water-bodies. The clinical presentation is often indistinguishable from acute bacterial meningitis and the diagnosis can be made by CSF wet smear examination if there is a high index of suspicion. The disease progresses rapidly compared to pyogenic meningitis and usually has a fatal outcome. Reports of two confirmed cases of primary amoebic meningoencephalitis in children from different centres in Kerala state of India are presented here. In spite of early diagnosis and treatment, both these patients demised. Primary amoebic meningoencephalitis should be considered in the differential diagnosis of acute meningitis, especially in patients with recent freshwater exposure. Implementation of chlorination of pools of water bodies, especially if re-opened for recreational purpose after prolonged periods of non-use, needs vigorous implementation.
