What's the difference between cercaria and cercarian?
Cercaria
Definition:
(n.) The larval form of a trematode worm having the shape of a tadpole, with its body terminated by a tail-like appendage.
Example Sentences:
(1) Between the 24th and 29th day mature daughter sporocysts with fully developed cercariae ready to emerge, or already emerged, could be seen in the digestive gland of the snail.
(2) The cercaria, microcercous in type, is liberated and actively penetrates a second terrestrial pulmonate where development to the free metacercarial stage takes place in the pericardial cavity.
(3) Low concentrations of cercaricides are toxic both for cercariae and parthenites from the liver of mollusks and for freely swimming cercariae.
(4) The cercariae shed from the snails were again exposed to several species of fresh water snails in order to observe metacercarial formation in the snails and their infectivity to final hosts.

(6) Immunoreactivity is strong in cercariae, but is essentially absent in miracidia.
(7) Cercariae in anaerobiosis, however, excreted as much as 15 times more lactate than under air.
(8) Twenty-eight Friesland calves were infested at 7 to 11 months of age with 5 000-45 OOO cercariae of Schistosoma mattheei.
(9) In vitro blastogenic responses of peripheral blood mononuclear cells (PBMN) to heterogeneous schistosome-derived antigens (eggs, SEA; adult worms, AW; and cercariae, CERC) were evaluated.
(10) Although vaccination of animals with these antigens does not result in consistent levels of protection exceeding 50%, the reproducible induction of about 80% protection with live attenuated cercariae indicates that immunization against schistosomiasis is achievable.
(11) The cercariae of the above species, recorded in Laos for the first time, are illustrated and their morphology is briefly described.
(12) Using the same mixture of cercariae, a Gelada baboon (Theropithecus gelada) could be infected by both schistosomes, but a dog was completely refractory.
(13) The model was then used to design a peptide inhibitor with 4-fold increased solubility, and a series of synthetic inhibitors were tested against live cercariae invading human skin to confirm that predictions of the model were also applicable in a biologic assay.
(14) Cystophorous cercariae from Retusa obtusa (Montagu) (Gastropoda, Opisthobranchia, Retusidae) develop into adults of Brachyphallus crenatus (Rudolphi, 1802) Odhner, 1905 (Hemiuridae).
(15) Preliminary results indicated that immunization with attenuated cercariae was capable of imparting protective immunity in mice.
(16) From original observations and from data in the literature, a key to cercariae of British strigeoids for which life-cycles are known has been compiled.
(17) Results of the infection of golden hamsters with different dozes of cercariae have shown that with the increase of dozes of infectious material the infection rate of helminths rises during the experimental intestinal schistosomiasis only to a definite level, which is attained by the injection of cercariae into the portal vein in dozes lower than those used for subcutaneous infection.
(18) The comparison between several cercariae of Microphallidae parasites of Birds had allowed to separate the ciliary characters of the two genera Microphallus and Maritrema.
(19) Experiments were conducted on the duration of life in sea water of three species of cystophorous cercariae from the Barents sea.
(20) The higher susceptibility of B. glabrata results in greater power of penetration into mice tegument on the part of the cercariae.
Cercarian
Definition:
(a.) Of, like, or pertaining to, the Cercariae.
(n.) One of the Cercariae.
Example Sentences:
(1) When the main producers of useful production perform as eliminators, the organic substance contained in eggs and cercarians transforms into economically useful production.
(2) It was shown that the summary mass of eggs entering biocoenosis exceeds considerably the biomass of adult trematodes; so the biomass of cercarians can amount to 50% of biomass of the infected part of mollusk population.
(3) Two groups of schistosome have been established on basis of cercarian morphometry with S. intercalatum, S. mansoni and S. rodhaini from one side, S. haematobium and S. bovis to the other side.
(4) The "cercarian chaetotaxic index" from the human strain of Schistosoma mansoni from West Africa is conspicuously modified during the third transmission Biomphalaria pfeifferi-white mouse only.
(5) 3 species of cercarians (Echinostoma sp., Echinoparyphium recurvatum, Asymphylodora sp.
(6) The cercarian body (Cbl) and tail-furcae lengths (Ctl) were measured, the values of which were treated using a computer.
(7) In the pre-laying phase one studied the forms of cercarian dermatitis, prodromic and inapparent.
(8) These tubules are unique to the striated muscle of the cercarian tail and may have functional significance.
(9) The most part of eggs and cercarians is eliminated in biocoenosis by biotic and abiotic environmental factors and is included into biocoenotic trophic chains through eliminators or saprophags.
(10) The evaluation of the biomass of eggs and cercarians of some species of trematodes is done.
