evaluation of soluble-antigen fluorescent antibody test for antibodies to trichinella spiralis in experimentallly infected swine.the soluble-antigen fluorescent antibody (safa) test was evaluated at intervals from 7 days to 1 year in 42 swine infected with 25, 100, 500, 2,500, 12,000, or 250,000 trichinella spiralis larvae. serums were test positive as early as 14 days after exposure in swine fed 25 larvae and as early as 7 days in swine fed 100 or 500 larvae. serums of all swine fed larger numbers of larvae were test positive by day 17 and remained test positive for the duration of the experiment. fluorescence obtained i ...19751094864
[immunofluorescence technique in diagnosis of trichinellosis in swine. i. investigations with the tube test (author's transl)].experiments have been made with serological demonstration of trichinella spiralis infections in swine. the technique applied was the indirect immunofluorescence tube test with whole larvae of t. spiralis as antigen. the blood samples tested were taken from groups of spf swine inoculated with, respectively, 50, 150, 500 and 1500 trichinella larvae. in animals inoculated with at least 150 larvae, antibodies could be demonstrated 3-5 weeks p.i. until the investigation was finished 6-7 months later. ...19751096075
[immunofluorescence technique in diagnosis of trichinellosis in swine. ii. comparative investigations with the tube test and the cryostate method (author's transl)].a series of comparative if tests have been made on serum samples from 9 spf pigs experimentally infected with trichinella spiralis (50-500 larvae per animal). the techniques applied included a tube test (antigen: whole trichinella larvae), and a cryostat test (antigen: sections of trichinella larvae). with the cryostat test a positive reaction was recorded in 2 animals already on the 6th day and in 5 animals on the 13th day p.i., while with the tube test such reaction was not demonstrated until ...19751096076
application of immunofluorescence and immunoenzyme methods in the serodiagnosis of trichinella spiralis infection.to detect antibodies to t. spiralis in sera, the if methods with the cuticle of t. spiralis larvae (the tube test) was compared to the cryostat method. in the latter method, cryostat sections were prepared from isolated t. spiralis larvae or from tongue or diaphragm musculature in which encysted t. spiralis larvae were present. in this case, both cuticle and internal structures were employed as antigenic sites. the cryostat method proved to be more sensitive than the tube test. with the cryostat ...19751101773

adaptive changes in muscle fibers infected with trichinella spiralis.ultrastructural changes which occurred in infected skeletal muscle fibers after infection with larvae of trichinella spiralis were followed on a daily basis utilizing synchronous infections. no changes were observed in muscle fiber architecture during the first 2 days of intracellular infection. however, on day 3, a space containing various sarcoplasmic elements developed between the plasma membrane and myofilaments. widening near the regions of triads was also observed at this time. on day 4 th ...19751119537

the development of alkaline phosphatase in trichinous muscle.the development of alkaline phosphatase during invasion and encystment of trichinella spiralis in rat skeletal muscle fibres was studied at the ultrastructural level. on day 14 after infection, the enzymatic activity is found in proliferating parts of the t-tubular system and in parts of the plasmalemma. in cells, in which a strong hyperplasia of this system is noted. alpase is present in the abundant network of stratified and concentric membranes from which a large number of pinocytic vesicles ...19751150485
[effect of trichinella spiralis infection on the development of rauscher leukemia].the influence of trichinella spiralis on the course of rausher leukemia in mice was studied. inoculation of mice with trichinella spiralis larvae 15, 16 and 30 days before infection with rausher leukemia virus was shown to stimulate splenomegaly, whereas preinoculation of rausher leukemia virus at 6, 12 and 18 days before infection with trichinella spiralis resulted in inhibition of splenomegaly. under the experimental conditions used, no effect of t. spiralis on reproduction of rausher leukemia ...19751162955
immunity to trichinella spiralis vi. the specificity of the immune response stimulated by the intestinal stage.mice were immunized to the intestinal stage of t. spiralis by using infections terminated with methyridine before production of newborn larvae had commenced. the muscle larvae which encysted following a normal complete challenge infection were reduced by 87 and 95% in immunized mice. no statistically significant reduction in a challenge infection of intravenously injected parenteral larvae was produced (8% and 15% actual reduction). previous work has shown that adult worms in a challenge infecti ...19751168664
quantitative study of the effect of previous trichinella spiralis infection on sarcoma 180 ascitic tumor formation in mice.tumor development in ham/icr mice inoculated intraperitoneally with sarcoma 180 (s-180) can be easily quantitated by linear regression analysis of non-destructive measurement of total body mass. this procedure readily separated the postinoculation period into incubation and clinical phases. the former was dependent on s-180 dose, while the latter was not. trichinella spiralis infection 28 days prior to s-180 challenge produced small but statistically significant increases in the length of both t ...19751189027

[the effect of trichinella spiralis on the susceptibility and antibody production to vaccinia virus].trichinella spiralis exerts an immunodepressive effect on production of antihemagglutinins to vaccinia virus in mice, increases the susceptibility to the virus in mice and rabbits. deaths of mice inoculated with vaccine virus and generalization of the vaccination process in rabbits were observed at 33 days of invasion.19751216835

trichinosis (trichinella spiralis infestations) in wild animals of the kruger national park.in africa trichinosis is essentially a disease of wild carnivores. once established in a suilline cycle it becomes a more important threat to man. the results of tests on 8,000 specimens of 20 wildlife species in the kruger national park are discussed and the epizootiology of trichinosis in south africa is briefly reviewed. the first case of trichinosis in an african civet, viverra civetta schreber, 1776, is reported. the confirmed absence of trichinosis in true herbivores is of practical signif ...19751240968
immune response to trichinella spiralis in the rat. i. development of cellular and humoral responses during chronic infection.the immune response of rats to infection with trichinella spiralis was studied serially for more than 1 year. initial antigen-specific cellular reactivity, assessed by the lymphocyte transformation response, developed in the draining mesenteric nodes 3 days after infection. after 1 week reactive lymphocytes were detectable in the spleen and circulating blood, but the more 'remote' peripheral nodes did not harbor antigen-reactive cells until late in the second week. thereafter, the patterns of an ...19751080134

decreased susceptibility to listeria monocytogenes in mice after infection with trichinella spiralis.mice challenged intravenously with listeria monocytogenes at 7 or 21 days after trichinella spiralis infection demonstrated a higher mean lethal dose and longer survival time than normal mice. this effect of helminthic infection was abrogated after 49 days.19744205953

comparison of three methods for the detection of trichinella spiralis infections in pigs by five european laboratories.three methods employed in the diagnosis of trichinosis (trichinoscopy, digestion method, and immunofluorescence technique) were compared by laboratories in 5 countries of the european economic community. for this purpose, material from 32 pigs infected with 50, 150, 500, and 1 500 t. spiralis larvae was examined. with none of the three methods was it possible to detect with sufficient reliability a t. spiralis infection in pigs infected with 50 larvae. the digestion method and the immunofluoresc ...19744616776
