A total of 480 snails were collected from 3 habitats on the Mau Escarpment, Kenya, and were identified asBulinus tropicus. Of the 351 snails examined alive in London, 75 were infected withCalicophoron microbothrium, 39 withC. microbothrium andSchistosoma bovis, 1 withS. bovis. 24 with other species of trematodes and 212 were uninfected.

Bjarnason, Bjarnason, Edwards, Fridriksson, Magnusson, Mourant and Tills (1973) published preliminary data on a study of Iceland. The present paper gives the complete data of the study and extends the sample size for most of the genetic systems to over 1500 individuals, approximately 1/130 of the population. The sample was divided into seven subpopulations(More)
Blood samples from the Waskia and Takia populations of Karkar Island, Papua New Guinea, and other nearby mainland populations, were tested for genetic variation in blood group, serum protein and red cell enzyme systems. Polymorphic variation was present in the ABO, P, MNS, Rh, Lewis, Duffy, Kidd and Gerbich blood group systems, in the Hp and Tf serum(More)
A series of 1,187 blood samples from eight population groups in the Eastern Highlands of Papua New Guinea were tested for genetic variation in blood groups, serum proteins and red cell enzyme systems. The populations belonged to the language groups Gahuku-Asarc-Bena Bena, Kamano, Yagaria, Keiagana, Fore, Agarabe, Auyana and Tairora. Polymorphic variation(More)
A series of blood samples from four villages in the Jimi Valley, Western New Guinea Highlands, has been tested for genetic variation in blood group, serum protein, and red cell enzyme systems. Polymorphic variation was present for the ABO, MNS, P, and Rh blood group systems, for the Hp and Tf serum protein systems, and for the acid phosphatase, 6-PGD, PGM,(More)
Blood groups and protein and enzyme polymorphism distributions were studied in 285 residents on the Isle of Lewis, in the Outer Hebrides. As well as gene frequency calculations for individual loci, genetic distance estimations were made and a phylogenetic tree was constructed. The results indicated several major differences from North-west European(More)
The diet of brown trout (Salmo trutta L.) and rainbow trout (S. gairdneri Richardson) in Rutland Water were compared during the first two fishing seasons (April–October 1977 and 1978). Fortnightly samples of approximately forty stomachs were obtained from boat and bank, rod-and-line caught trout giving a total of 1046 stomachs over the two seasons. During(More)
Blood specimens collected fro Yemenite and Kurdish Jews living in Israel were tested for 11 blood group systems 5 plasma protein systems and 9 systems of red-cell enzymes. The results of these tests were combined with those of tests on other Yemenite and Kurdish Jews, reported by Godber et al. (1973), the total data sorted according to the place of origin(More)
Indoplanorbis exustus is the intermediate snail host of both Schistosoma nasale and S. spindale in Sri Lanka. Due to the similar morphology of the cercariae difficulties exist in identifying the species of schistosome infecting snails at transmission sites.
