Abstract

We had the opportunity of studying an epidemic of autochthonous amoebiasis occurring in the autumn of 1974 in a small town of 4000 inhabitants 30 km from Grenoble. Attention was originally attracted by the occurrence in this town of two cases of hepatic amoebiasis and one of intestinal amoebiasis identified by rectoscopy. Systematic investigations (coproctic examinations and serological tests for amoebiasis by indirect antibody fluorescence) were then carried out on everyone in the locality with digestive disorders which were possibly referable to amoebiasis, and on the other members of their families. A total number of 148 coproctic examinations were made and in two cases revealed the presence of vegetative forms of Entamoeba histolytica. In both cases the infestation provoked few symptoms (asthenia, vague abdominal discomfort, intermittent and apparently banal diarrhoea). On the other hand 20 out of 94 serological tests revealed positive results, 14 of which were equal to or greater than a titre of 1/100, a level at which all risks of non-specificity are virtually ruled out under our experimental conditions. Material reasons made it impossible to subject these cases to repeated faecal checks, but in two of them at least the r...Continue Reading
