The present review shows how recent research on human and animal genome sequences and on gene mapping and cloning is enabling the identification of disease susceptibility genes, which will help to prevent and treat the various forms of leishmaniasis. The authors describe how the mouse has proved to be a particularly fruitful host since there are inbred strains with different susceptibilities to infection, particularly to T-cell responses. Combined with clonal parasite lines, unaccountable variations in parasite virulence can be removed and the genes involved in host response to infection will be increasingly obtainable. The second paper by Andrew Thompson and Nawal Hyjjawi of Murdoch University, Australia, Merle Olsen of the University of Calgary, Canada, Guan Zhu and Shinichiro Enomoto of Texas A & M University, USA and Mitchell Abrahamansen of the University of Minnesota, USA, provides a comprehensive review of all aspects of recent research on Cryptosporidium in a variety of hosts. Most work over the last 10 years has concentrated on the development and application of molecular tools to solve questions about the epidemiology and zoonotic potential of this parasite. However, recent developments in in vitro cultivation, life cycle (including previousl
