Genetic exchange between cells of Trypanosoma brucei that occurs in the tsetse fly vector (Jenni et al. 1986) is an important part of the life cycle that contributes significantly to genetic diversity of these human pathogens (Gibson and Stevens 1999). Indirect observations have also indicated the presence of sexuality during the development of Trypanosoma cruzi (Bogliolo et al. 1996; Stothard ...

time in development. The third part is a discussion of the metabolic processes involved in growth and differentiation. The vast amount of material covered is very well handled under many subdivisions which make it easy to refer to special topics. Since the text is thoroughly documented the reader will find in the 70 pages of bibliography and 19 pages of index a ready source to the original lite...

Experimental Parasitology 92, 57–63. Isoenzyme electrophoresis and RAPD techniques were used to study the genetic polymorphism of different Spanish isolates of Theileria annulata in the schizont and piroplasm stage...
