What's the difference between amphid and nematode?
Amphid
Definition:
(n.) A salt of the class formed by the combination of an acid and a base, or by the union of two oxides, two sulphides, selenides, or tellurides, as distinguished from a haloid compound.

(15) The histochemical pattern of acid phosphatase activity in the microfilaria of L. loa showed a diffuse red staining all over the body, with conspicuous staining of the excretory and anal vesicles, Innenkörper, amphids and phasmids.
(16) The morphological surfaces of the anterior end, head spine, body cuticle, amphid, papillae, posterior end of larvae were described and compared with the advance third-stage (aL3) larvae.
(17) Head shape, cuticle, and intestinal ultrastructure are nondauer, whereas sensory structures (amphid and deirid) and excretory gland morphology are intermediate between that of dauer and nondauer stages.
(18) The presence or absence of enzymic activity in the excretory cell complex and in the Mundgebilde (amphids) of the developing larvae can be used as an adjunctive diagnostic method.
(19) The amphid cilia in che-11 (e1810) are irregular in diameter and contain dark ground material in the middle of the axonemes.
(20) One of these pairs consists of medium-sized lateral ganglia neurons, located at the level of the amphid commissure bundle.
Nematode
Definition:
(a. & n.) Same as Nematoid.
Example Sentences:
(1) The faeces of forty-two were examined microscopically for nematode eggs.
(2) The propionyl-CoA condensing enzyme which catalyzes the first step in the biosynthesis of 2-methylbutyrate and 2-methylvalerate by Ascaris muscle appears to exist in at least three forms in the mitochondria of this parasitic nematode.
(3) Haematological and blood biochemical changes in the sheep, as well as fecundity of gastrointestinal nematodes, suggested the hosts were immunosuppressed.
(4) We have studied the organization of microtubules in neurons of the nematode Caenorhabditis elegans.
(5) At the external wall of the host's gut, parasitic cysts of this nematode with immature stages inside were also observed.
(6) Mice (C57BL) infected with the intestinal nematode Nematospiroides dubius showed depressed delayed type hypersensitivity responses to ovalbumin administered subcutaneously in Freund's complete adjuvant.
(7) Additionally, both nematode enzymes acetylated histamine, whereas dopamine and serotonin were not accepted as substrates.
(8) The study design of a project to investigate the epidemiology, population dynamics and control of intestinal nematode infections in fishing village communities in Southern India is described.
(9) Two control trials were conducted against Ae.samoanus larvae in Pandanus, one using a sand culture of the parasitic nematode Romanomermis culicivorax and the other with temephos, an organophosphate insecticide.
(10) Lesions associated with Philometroides huronensis in the white sucker (Catostomus commersoni) of southern Ontario occurred during the spring (April-June) and were related to the development and release of first-stage larvae from the gravid nematode.
(11) Hypoproteinaemia, attributed to serum albumin loss, was demonstrated seven weeks after infection, but this was not associated with the interaction of Cu deficiency and nematode infection.
(12) Five cases shown to be positive by traditional methods were negative in the agar plate method, and it was necessary to discriminate Strongyloides microscopically from other similar nematode larvae, especially in an area, such as northern Thailand, with a high prevalence of hookworms.
(13) Using bronchoalveolar lavage (BAL) we have retrieved soluble proteins and cells from the respiratory tract of rats given a primary or secondary infection with the nematode Nippostrongylus brasiliensis.
(14) Specific binding sites for ivermectin (IVM; 22,23-dihydroavermectin-B1) were identified and characterized in a crude membrane fraction prepared from the nematode, Caenorhabditis elegans (C. elegans).
(15) The association of SL-RNA and 5S rRNA genes in tandemly repeated units is also found in nematodes but paradoxically does not exist in trypanosomes which are phylogenically much closer to Euglena.
(16) We sought genes defining synaptic specificity by identifying mutations that alter synaptic connectivity in the motor circuitry in the nematode C. elegans.
