| Summary: | It is hoped this book will be of practical use to parasitologists, physicians,
veterinarians, zoologists, and wildlife and fisheries biologists and that it will encourage a
fresh appreciation of the astonishing diversity of ‘life styles’ even within superfamilies
often regarded as biologically homogeneous. For example, the trichostrongyloids range
from the typical gut parasite with the usual free-living larvae, to species which are
transmitted by emesis and others which live in bile ducts and mammary glands of their
hosts. The lungworms (metastrongyloids) range from typical inhabitants of the lungs
which use molluscs as intermediate hosts, to forms in which first-stage larvae passed in
faeces or vomit are the infective stage. In the dracunculoids of marine fish are found
species in which first-stage larvae are microfilarioid and occur in the blood, where they
are available to blood-sucking crustacean intermediate hosts – a remarkable convergence
with the distantly related filarioids of terrestrial vertebrates. In the filarioids transmission
ranges from the Filariidae, which release eggs into the environment by means of a break
in the skin, to louse-transmitted, ephemeral Onchocercidae, which flood the skin of
shorebirds with long-lived microfilariae and then disappear. |
