Histopathology and Immunohistochemistry
According to Lühe (1904), the earliest description of Acanthocephala, namely those worms having a proboscis armed with hooks, was made by Italian author Francesco Redi (1684). Since then, many eminent parasitologists have studied the biology of this group of helminths. The Acanthocephala represent an entirely parasitic taxon of pseudocoelomate worms, containing over 1150 species. Adults live as endoparasites in the alimentary canal of all classes of vertebrates in marine, freshwater, and terrestrial habitats and larvae live in the body cavity of arthropods. The arthropod becomes infected by eating the mature egg, from which the acanthor larva is freed into the lumen of the invertebrate's digestive tract. Later, this larva bores into the gut wall and enters the hemocoel. Here, development of the parasite proceeds through the acanthella stage up to the cystacanth stage, which can infect the vertebrate host after the arthropod is ingested. Acanthocephala exhibit considerable uniformity of structure and similarity in life cycles and reproductive processes. All acanthocephalan worms are dioecious and their reproductive organs are highly characteristic.
The most noticeable difference between the sexes of acanthocephala is that of body size; the female specimen is longer than the male (Parshad and Crompton, 1981). Other sexually dimorphic traits appear as differences in external features such the size and shape of the proboscis, as well as the size and shape of the attachment organ's hooks, the distribution of body spines, the presence of papillae and the position of genital orifices (Van Cleave, 1920; Yamaguti, 1963).
Acanthocephala have cylindrical or flattened bodies, usually white in color, with some species slightly yellow to orange. Most species are not much more than 1 cm in length, but some measure up to 70 cm. The body consists of two parts:
I - The praesoma comprises the armed proboscis, a more or less pronounced neck, the proboscis receptacle and a paired structure termed lemnisci which protrudes inwards from the inner surface of the neck wall;
II - The metasoma or trunk encloses the pseudocoel, in which are suspended the reproductive organs of Acanthocephala.
The classification of the Acanthocephala presented below is based on concepts proposed by Amin (1987). According to this scheme the phylum consisting of four classes, namely Palaeacanthocephala, Archiacanthocephala, Polyacanthocephala and Eoacanthocephala.
Acanthocephala attain sexual maturity in the digestive tract of the definitive host (vertebrates), generally in a specific site (Crompton, 1973). In this phylum sexual reproduction is the only form that occurs. In fact, in this group of helminths parthenogenesis, hermaphroditism and other forms of asexual propagation are unknown (Van Cleave, 1953; Kennedy, 1993).
Much of our knowledge concerning the ultrastructure of spermatogenesis and spermatozoa of Acanthocephala is due to the contributions of Marchand and Mattei (see Crompton and Nickol, 1985). More work has been done on spermatogenesis and the structure of the spermatozoa than on the testes.
Acanthocephalan biology was published in a monograph edited by Crompton and Nickol (1985), and recently the reproduction of the phylum has been reviewed by Carcupino and Dezfuli (1999).
