Rediae

Rediae, if present, develop from germ balls in the brood chamber of the primary sporocyst. They eventually escape from the sporocyst through the molluskan tissue and migrate to the digestive gland. Each redia is elongate and normally possesses two or four bud-like, antero- and posterolateral projections, the ambulatory buds (or procruscula ) ( Fig. 9.20 ) Redbridge Institute is the leading local provider of adult learning and education in the London Borough of Redbridge.

Redia definition is - a larval form of a digenetic trematode (such as a liver fluke) that is produced within a sporocyst, has a mouth, pharynx, and gut, and contains cells which give rise to other rediae or to cercariae

Redia. one of the parthenogenetic generations of the digenetic flukes, or trematodes, which parasitizes an intermediate host (mollusks). The redia develops in the body cavity of the worm's first parthenogenetic generation, the sporocyst. It in turn produces the cercaria, the larvae of the sexually mature flukes Trematode (Fasciolopsis buski) Rediae. A parasitic trematode, Fasciolopsis buski is known as the giant intestinal fluke of man, but may also infect swine. In their adult form, the worms attach themselves to the tissues of the small intestine through the use of ventral suckers and may reach up to 7.5 centimeters in length

Rediae of an unidentified echinostome were transplanted from naturally infected Physa hetero-stropha into the neck of Australorbis glabratus. Dissection of A. glabratus 1, 6 or 10 days later yielded 57 rediae, all of which were dead. Almost half of the rediae contained up to 3 metacercariae. Metacercariae were absent in 900 rediae dissected from P. heterostropha High immunogenicity of the crude extract of rediae (third antigen), mainly related to parasite's specific epitopes, was regarded. Therefore, the rediae homogenate is stated as the most promising antigen from those evaluated, for monoclonal antibody development with potentialities for detecting F. hepatica-infected snails.

Rediae, similar to the sporocyst, are essentially baglike animals, with the majority of the body devoted to a uterus-like sack in which germ balls develop into either daughter rediae or cercariae (Martin 1950). Unlike the sporocyst, rediae are much smaller, unbranched, possess a mouth, pharynx, and blind gut, and are capable of locomotion The miracidium is transformed into a sporocyst in which mother rediae (distinguished from the sporocyst by the presence of a pharynx) develop. In these, daughter rediae (also with a pharynx) develop. Daughter rediae in turn give rise to cercariae, which leave the redia, escape from the snail and encyst on some substratum thus forming a. The miracidia undergo several developmental stages in the snail, i.e. sporocysts , rediae , and cercariae . Many cercariae are produced from each redia. The cercariae are released from the snail and encyst as metacercariae in the tissues of a suitable fresh/brackish water fish (second intermediate host) . The definitive host becomes infected by. Rediae migrate to liver of snail and produce up to 9 daughter rediae Each redia gives rise to 9-10 cercariae Thus, reproductive potential approximately 1:1,000 over a period of 40-60 days, temperature dependent.

Images of egg (eggs), miracidium (miracidia), sporocyst (sporocysts), redia (rediae), cercaria (cercariae), and. Once inside, miracidia go through several metamorphoses first becoming sporocysts that give rise to mother rediae which in turn produce daughter rediae. Germ balls develop inside the daughter rediae that become cercariae which will grow and bore back out of the snail to again become free-swimming in the environment The different intramolluscan stages were transferred to a glass slide for detailed examination. For light microscopic studies, miracidiae were fixed in 5% neutral formalin, cercariae, rediae and metacercariae were fixed in 10% neutral formalin for 2 h Receptors of P. gralli rediae are less dense, appear to have rigid cilia, and lack a bulbous base. In general P. megalurus rediae resemble more closely rediae of the philophthalmid Parorchis acanthus than they do those of P. gralli. Several studies have described the surface fea-tures of the redial stage of digenetic trematode

The rediae collected from S. quangtriensis possessed a long intestine (about 75% of the body length) and each redia contained 6-8 cercariae.

They have a rudimentary but functional digestive system consisting of a pharynx, and short gut. The embryos inside the redia develop into daughter rediae or into the next stage called cercariae. 4

rediae in Himasthla sp. B colonies do not produce cercariae and are specialized for attacking and killing conspecific or heterospecific competitors. Thus, for the first time, they documented a repro-ductive di vision of labor in a parasitic flatworm involving a non-reproductive soldier caste.

Division of labour has evolved in many social animals where colonies consist of clones or close kin. It involves the performance of different tasks by morphologically distinct castes, leading to increased colony fitness. Recently, a form of division of labour has been discovered in trematodes: clonal rediae inside the snail intermediate host belong either to a large-bodied reproductive caste.
