OnSchistosoma leiperi Le Roux, 1955: scanning electron micrscopy of adult worms, compatibility with species ofBulinus, development inMesocricetus auratus, and isoenzymes (original) (raw)

Abstract

Adult male and female_S. leiperi_ Zambia were examined by scanning electron microscopy. The oral and ventral suckers of both sexes are described, as is the gonopore of the female. The surface of the male is tuberculate whereas that of the female is non-tuberculate. The tubercles of some male worms are heavily spined., whereas those on other males are without spines. The gynaecophoric fold and canal are covered in spines.

The compatibility of_S. leiperi_ Botswana, and Zambia with species of_Bulinus_ has been examined. Both isolates develop well in snails belonging to the_B. africanus_ group (B. africanus, B. globosus, B. hightoni, and_B. nasutus_) and_B. reticulatus_ group (B. wrighti) but are incompatible with snails belonging to the_Bulinus tropicus/truncatus_ complex and_B. forskali_ group.

The overall worm return from 32 hamsters exposed to 100 cercariae each of_S. leiperi_ Botswana, was 26.1% and of these 85.1% of the worms were paired, the remainder single. The growth and maturation of the worms were recorded from 40–100 days. The prepatent period in hamsters is 49 days. Most eggs were recovered from the liver (79.5%). The following enzymes of adult male worms were examined by isoelectric focusing:S. leiperi Zambia — phosphoglucomutase (PGM), glucose-6-phosphate dehydrogenase (G6PDH), hexokinase (HK), acid phosphatase (AcP), glucose phosphate isomerase (GPI), malate dehydrogenase (MDH), and lactate dehydrogenase (LDH);S. leiperi Botswana — PGM, G6PDH, GPI.
