Experimental Studies on Dibothriocephalus latus in Man

Abstract

1. Infection with Dibothriocephalus latus for as long a period as nine months or with as many as three worms, apart from diarrhoea in the early stages does not necessarily give rise to any symptoms which would suggest the presence of the parasite.2. In these experimental cases a definite train of symptoms, i.e., constipation for a period of one or more days followed by diarrhcua marked the onset of complete sexual maturity of the parasite.3. No appreciable anaemia was produced, nor was there a definite diminution of erythrocytes.
