Studies on schistosoma haematobium in the laboratory II. A strain from South Arabia

Abstract
Some of the characteristics of a strain of S. haematobium from South Arabia in experimental infections in hamsters are described. The relationship between the state of maturity of the intra-molluscan phases of the larvae and subsequent success of the cercariae is discussed. Growth curves for the adult worms and changes in uterine egg count with age are illustrated. The quantitative distribution of parasite eggs in the host tissues is described and approximate figures for the daily egg output of individual worms are given. The effects of host sex on worm burden and parasite sex ratio are discussed. The characteristics of this strain are compared with those of a strain from South Africa.
