What's the difference between parasitic and trichina?
Parasitic
Definition:
(a.) Alt. of Parasitical
Example Sentences:
(1) The rise of malaria despite of control measures involves several factors: the house spraying is no more accepted by a large percentage of house holders and the alternative larviciding has only a limited efficacy; the houses of American Indians have no walls to be sprayed; there is a continuous introduction of parasites by migrants.
(2) However, ticks, which failed to finish their feeding and represent a disproportionately great part of the whole parasite's population, die together with them and the parasitic system quickly restores its stability.

(6) Filipin-induced lesions in glutaraldehyde-fixed parasites indicated higher levels of beta-hydroxysterols in the amastigote than in the promastigote plasma membrane, and in the promastigote flagellar membrane than in the body membrane.
(7) 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.
(8) The time to recovery of full consciousness, time to parasite clearance, and mortality were examined with Cox proportional-hazards regression analysis.
(9) In addition, a redistribution of cellular controls of the host reaction to parasites may act as a complementary mechanism for establishment of the viable equilibrium between host and parasite.
(10) symptoms, bowel habits, normal physical examination, absence of intestinal infections or parasites) b) physiopathological evaluation (hyperactivity of the distal colon, hypersensitivity to stimuli, stress), and c) physiological evaluation of the patient.
(11) Parasite antigen was present in sera from all infected animals before treatment.
(12) We have found intrathrombocytic parasites of Plasmodium vivax (in 10% of men naturally infected) and P berghei (in 53% of mice experimentally infected); these were both merozoites and trophozoites.
(13) they are shown to inhibit in vitro the release of iron from acidified host cell cytosol, consisting mostly of hemoglobin, a process that could provide this trace element to the parasite.
(14) Phagocytosis of normal or parasitized red cells was not observed.
(15) A radical rearrangement of the organism occurred gradually: initially oval in shape, the parasite became round, then elongated, flattened, and underwent cytokinesis.
(16) The parasites were highly aggregated within the study community, with most people harbouring low burdens while a few individuals harboured very heavy burdens.
(17) Discovery of this vectorhost-parasite system in the Americas, and the localization of promastigote flagellates (leptomonads) in the hindgut of the vector, should assist in clarifying interpretative problems associated with infection of wild-caught flies in studies on leishmaniasis in the Americas and elsewhere.
(18) At the external wall of the host's gut, parasitic cysts of this nematode with immature stages inside were also observed.
(19) All three parasite lines required sialic acid for optimal invasion, but Thai-2 parasites cultured in Tn erythrocytes invaded neuraminidase-treated erythrocytes with 45% efficiency whereas Camp parasites invaded neuraminidase-treated erythrocytes with less than 10% efficiency.
(20) Pretreatment of G6PD(+) cells with ascorbate caused a slight enhancement in parasite development, while in G6PD(-) cells a suppressive effect on the plasmodia was demonstrated.
Trichina
Definition:
(n.) A small, slender nematoid worm (Trichina spiralis) which, in the larval state, is parasitic, often in immense numbers, in the voluntary muscles of man, the hog, and many other animals. When insufficiently cooked meat containing the larvae is swallowed by man, they are liberated and rapidly become adult, pair, and the ovoviviparous females produce in a short time large numbers of young which find their way into the muscles, either directly, or indirectly by means of the blood. Their presence in the muscles and the intestines in large numbers produces trichinosis.
Example Sentences:
(1) The ability of Trichinella spiralis larvae to survive at subfreezing temperatures encysted in the musculature of wild carnivorous mammals was assessed by evaluating motility and infectivity (to rodents) of trichinae at various intervals after storage in frozen skeletal muscle.
(2) Seroconversion occurred in all pigs given infective Trichinella larvae although no trichinae were recovered from pigs given T. spiralis nativa larvae and examined between days 92 and 99 postinfection by pepsin digestion.
(3) All other bioassays carried out on Genoa salami between 13 and 42 days postpreparation, on proscuittini between days 27 and 69 and on proscuitto between days 34 and 69 were negative for viable trichinae.
(4) Trichinae were present in greatest numbers in masseter, tongue and diaphragm.
(5) Trichina counts per gram of tissue obtained by the artificial digestion-Baermann method ranged from 1390 to 0.02.
(6) Little cellular reaction was observed surrounding trichinae after muscle invasion and cyst development was completed except for cysts undergoing disintegration.
(7) Eight patients were admitted to hospital; muscle biopsy was done on one serious case and trichina larvae were detected.
(8) Using the pooled-sample digestion technique, 3 dead trichina larvae were identified in 1 sample pooled from 15 diaphragms (10 g each).
(9) The first signs of the disease appeared on average 17 days after eating trichina-containing meat.
(10) Rat bioassay revealed the presence of viable trichinae in the proscuitto prepared using a sodium chloride salt mixture at day 34 but not at day 48 postpreparation.
(11) Temperature elevation of the swine did not affect the viability of the trichinae.
(12) At various times postpreparation, samples of the various cured products were taken and examined by pepsin digestion and rat bioassay for the presence of viable trichinae.
(13) In both cases, however, the diagnosis was established histologically by demonstrating trichina larvae in the patients' muscle biopsies.
(14) In pigs, even in those heavily infected, there is a lag between the period that trichinae in musculature become infective and development of antibodies as detected by enzyme-linked immunosorbent assay which results in false negative reactions in many animals.
(15) Viable trichinae were not recovered from ground bear meat preparations (pepperoni, salami, or sausage) processed according to commercial standards.
(16) Six California bears and one from Wisconsin contained more than one trichina per gram, a level considered capable of inducing clinical trichinosis in man.
(17) Results also demonstrated the presence of a critical temperature about minus 30 degrees C below which trichinae in meat do not survive for any appreciable period of time.
(18) Trichina larvae from hog cholera infected swine were freed from diaphragmatic tissue by artificial digestion.
(19) The survival and the transplantation of adult trichinae collected in cyclophosphamide treated and untreated mice were studied.
(20) Survival has not been reported previously in patients with greater than 1,000 trichinae per gram of muscle.
