What's the difference between ootype and trematode?
Ootype
Definition:
(n.) The part of the oviduct of certain trematode worms in which the ova are completed and furnished with a shell.
Example Sentences:
(1) Caulobothrium longicolle (Linton, 1890) and Phyllobothrium gracile (Weld, 1855) (Cestoda: Tetraphyllidea, Phyllobothriidae) have the same embryonic development with the following characteristic data: --a small number of vitelline cells (2 or 3) pass with the zygote in the ootype;--a non operculate thin egg-shell;--the entire and equal zyhote cleavage following by unequal divisions leading to the formation of four blastomere types (Macromeres, secondary Macromere, Mesomeres and Micromeres);--the differentiation of two syncytial embryonic envelopes during the preoncospheral phase.

(4) The formation of the egg mass in the ootype, containing the oocyte, vitelline cells, numerous spermatozoa and Mehlis' gland secretion marks the beginning of eggshell formation.
(5) The role of DB cells (which enter the lumen more commonly in the ootype near the oviduct) remains unknown.
(6) In the peripheral nervous system, immunoreactivity occurs in the nerve plexuses supplying the subtegumental musculature, the oral and ventral suckers, and the muscular lining of the male and female reproductive ducts, including the ootype, uterus, cirrus pouch and gonopore.
(7) The secretions produced by the Mehlis' gland and the distal ootype in Schistosoma mansoni were identified as neutral glycoproteins.
(8) The cell bodies are positioned in the parenchyma surrounding the ootype and taper to axon-like processes that extend to the ootype wall.
(9) In both unisexual and paired mature females part of the lining of the ootype is reactive, especially near the entrance of the vitelline duct; this demonstrates that females can make ecdysteroids without mal contact.
(10) Cells displaying immunoreactivity to PYY and FMRFamide lie amongst the Mehlis' gland cells that surround the ootype.
(11) Processes of the two cell types converge on the ootype-proximal uterine wall, pass through the epithelium, and finally open into the lumen.

(14) One group of PP-immunoreactive cells occurs at the junction of the vitelline and ovovitelline ducts, whilst another group is situated at the entrance to the uterus from the ootype.
(15) An ootype and a type of accessory reproductive gland not known from other Kronborgia spp.
(16) The terminal regions of these processes branch and anastomose and, in places, the swollen endings or varicosities form synaptic appositions with the muscle fibres in the ootype wall.
(17) Intense peptide immunoreactivity was identified in fibres in the wall of the ootype and in a surrounding population (greater than 100) of somata that were situated beyond Mehlis' gland cells and all of which were connected to the ootype wall by fine cytoplasmic connectives.
(18) testis 0-94 X 0.94; seminal vesicle 0-82 X 0-24; ootype 0-21 X 0-41; ovary 0-41 X 0-34; and egg 121 X 83 micrometer.
(19) It is concluded that the cells are neurosecretory in appearance and that, functionally, their secretions may serve to regulate ootype motility and thereby help co-ordinate egg production in the worm.
(20) In the peripheral nervous system, similar immunoreactivity occurs in the nerve plexuses supplying the sub-tegumental muscle layers and the muscular lining of various reproductive ducts, including the ootype, uterus and cirrus pouch.
Trematode
Definition:
(n.) One of the Trematodea. Also used adjectively.
Example Sentences:
(1) The adults of the trematode occurring in the nasal sinuses and posterior nasal passage of the dolphins are considered as practically harmless for the host but thier eggs, aspirated deep into the bronchial tree, may initiate a foreign-body of inflammatory reaction in the lungs and continuous aspiration of such eggs may provoke a chronic pneumonia condition.
(2) Mebendazole can be used against numerous nematode-infections (Ascariasis, Trichuriasis, Oxyuriasis, Ancylostomiasis), Niclosamide against cestode-infections (Taeniasis, Hymenolepiasis, Diphyllobothriasis), whereas, Praziquantel is applied against trematode-infections.
(3) Hand contamination with the infectious metacercariae of the digenetic trematode Nanophyetus salmincola (family Troglotrematidae) occurred during the handling of fresh-killed, juvenile coho salmon, Oncorhynchus kisutch.
(4) Ecdysteroids have been detected in trematode parasites and in several species of gastropod snails.
(5) Bithynia tentaculata, being the only snail species that was very numerous in the lake, was the first as well as the main second intermediate host; adult trematodes were found exclusively in the tench, Tinca tinca.
(6) Trematode diseases have remained the same, but the tools (1) to exploit the innate ability of cells to replicate and produce biological products upon demand, (2) to manipulate the genetic makeup of an organism, (3) and to biologically or synthetically manufacture peptides have provided scientists with new reagents for diagnosing, treating, preventing and controlling trematode diseases.
(7) This seems to suggest that the rediae of this species are incompatible with other trematodes in the snail.
(8) The objectives of this study were to 1) determine if exposure of M line or 10-R2 strain Biomphalaria glabrata snails to infection with the trematodes Echinostoma paraensei and Schistosoma mansoni could increase agglutinating activity in snail hemolymph, and 2) identify particular hemolymph molecules with such activity.
(9) Localization of catecholamines in the nervous system of 12 species of Trematodes parthenitae from marine mollusks has been studied using the method of glyoxilic acid-induced fluorescence.
(10) All patients were treated with a single dose of praziquantel (50 mg kg-1 body weight) and control stool tests performed on the 15th, 30th and 60th days post-treatment showed no trematode eggs.
(11) A study of the ultrafine structure, hysto- and biochemistry of trematodes will enable us to associate better the morphology and the function of organs and to go deeper into the functional morphology and functional biochemistry.
(12) The possession of common antigens by three trematode parasites which commonly occur together in ruminants in the tropics, Fasciola gigantica, Dicrocoelium hospes and Schistosoma bovis was studied in relation to the reliability of serodiagnosis of infection with these helminths.
(13) Infection or immunization with subcellular antigens of Fasciola hepatica confers high levels of immunity to a challenge infection with another trematode, Schistosoma mansoni.
(14) In vitro studies with Paramphistomum microbothrium indicated that the trematode is capable of synthesizing its complex lipids using exogenous substrates.
(15) These studies are revealing additional sites in trematodes that may be important for the development of new and more selective chemotherapeutic agents.
(16) In some trematodes, the caeca, especially in the brush border, and the tegument, subtegumental cells and testes, were reactive to the enzymes.
(17) New hosts are presented for the nematodes Cucullanus pinnai, Spirocamallanus inopinatus and Travnema travnema, for the trematode Pararhipidocotyle jeffersoni and for the acanthocephalan Gorytocephalus spectabilis.
(18) Further investigations are necessary to identify the species of this trematode and to understand if it is a true human parasite or a pseudoparasite.
(19) Trematodes found in 10 Numenius americanus from the Galveston area included Pelmatostomum americanum sp.
(20) Surgical repair of an inguinal hernia in a 19-year-old man in Honduras revealed massive numbers of small granulomata containing trematode eggs on the omentum and other peritoneal surfaces.
