Abstract
In 1968, a canal draining cooling water from a factory was the source of infection with primary amoebic meningoencephalitis (PAME) (1 case). The bed of the canal was lined with stone slabs and about 2 m wide. The flow rate of water was approximately 2 m/s. Average annual water temperatures ranged from 27-30.degree. C. In culture, N. fowleri was not found in the water of the canal, but it was present in scrapings off the canal walls and in its bottom sediment for a length of about 2 km, starting at the site of the water outlet from the factory. The maximum number of amoebae was 800/l of sample. The detective efficacy of the culture methods employed and the epidemiological bearing of the findings are discussed.
