Parasites

Despite their large size, protozoan parasites are particularly adept at avoiding the unwanted attention of their hosts. This remarkable ability highlights the need for equally clever strategies to prevent and treat infection. With parasitic diseases such asmalaria and sleeping sickness affecting manymillions in the developing world, recent research in genetics and cell biology provides us with ...

Parasites, Phylogeny, and Cospeciation

PAGE, R. D. M. 1993. Parasites, phylogeny, and cospeciation. International Journal for Parasitology 23:499-506. Host-parasite assemblages offer exciting possibilities for the comparative study of rates of speciation and evolution in different organisms. The basis for such studies must be a phylogenetic analysis of the host-parasite association. Some recent developments in this field are briefly...

Social Behavior and Parasites

Foodborne and waterborne parasites.

More than 72 species of protozoan and helminth parasites can reach humans by food and water, and most of these infections are zoonoses. Some parasites show a cosmopolitan distribution, others a more restricted distribution due to their complex life cycles, which need the presence of one or more intermediate hosts. Of this large number of pathogens, only Toxoplasma gondii can be transmitted to h...
