What's the difference between trichina and trichinae?
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.
