Impact of acute diarrhoea on parasite loads
Abstract:
Parasites and diarrhoea are more frequent in poor populations. Parasite prevalence rates in post-diarrhoeal patients of the International Centre for Diarrhoeal Disease Research (ICDDRB) and in non-diarrhoeal populations of two Dhaka poor socioeconomic communities have been compared to explore if there is any effect of acute diarrhoea on parasite prevalence rates. Stool of a 4% systemic randomly selected sample of diarrhoeal patients and the whole population of two local poor communities have been examined. The results showed that the prevalence of parasites in a post-diarrhoeal population is significantly lower than in a non-diarrhoeal population. These reductions (E. hist. 10.2% vs. 2.03%, G. lamb. 9.7% vs. 3.5%, hookworm 37.4% vs. 4.7% and Ascaris lumbricoides 81% vs. 20.6%) may be attributed mainly to the flushing effect of diarrhoea.
