modification of immune competence by parasitic infections. i. responses to mitogens and antigens in mice treated with trichinella spiralis extract.spleen cells from mice pretreated with a trichinella spiralis extract (tse-mice) showed severe depression of the response to lipopolysaccharide (lps) and to concanavalin a (con a), slight depression to phytohemagglutinin (pha) and normal response to tuberculin purified protein derivative (ppd) as compared to saline-pretreated controls. mice pretreated with bovine serum albumin (bsa-mice) revealed greatly reduced responses to lps, somewhat reduced response to con a, and normal responses to pha an ...1978682066
[trichinosis: epidemiology, clinical features and diagnosis (author's transl)].after ingestion of wild boar meat 58 patients developed typical clinical signs and symptoms of trichinosis. all patients had marked blood eosinophilia. in 45% of the patients got and gpt and in 62% hbdh were moderately increased, while in 76% ldh and in 86% creatine-kinase showed abnormally high values. ck-mb was increased in three patients. 92% of muscle biopsies showed typical morphological changes in skeletal muscles. latexagglutination, complement-fixation and agar-gel diffusion tests were n ...1978699765
[serum antibody findings in trichinosis (author's transl)].serum samples of 66 persons who had eaten meat from a wild boar were tested two to three times within 11 months for antibodies against extracts from trichinella larvae. watery extract of trichinella spiralis larvae served as antigen. complement-fixation was of little use because of its lack of sensitivity. indirect haemagglutination and the elisa test (enzyme-linked immunosorbent assay) gave uncertain results only in individual cases. there was a relationship between the clinical picture and the ...1978699766
trichinella spiralis infection in mice. mechanism of the resistance in animals genetically selected for high and low antibody production.mice genetically selected according to their capacity to produce antibody were orally infected with fifty muscle larvae. after 1 month, the number of larvae found in low responder mice was twice the number found in high responder mice. following a second infection, low responder mice were completely protected while high responder mice showed only partial protection. it is suggested that the better resistance of high responder mice after a primary infection is due to their high and rapid antibody ...1978700780

depression of cell-mediated immunity following inoculation of trichinella spiralis extract in the mouse.mice pretreated with trichinella spiralis extract (tse), or infected with the parasite, rejected primary skin allografts in 18-23 days and secondary allografts in 12-16 days. mice pretreated with saline or with bovine serum albumin (bsa) rejected the primary allografts in 12-18 days and did not accept the secondary grafts. inoculation of increasing doses of parental spleen cells from mice pretreated with saline or with bsa in f1 hybrids produced proportionately stronger graft-versus-host reactio ...197823994
[fractionation of the trichinella spiralis antigen and allergy diagnosis trails].experiments were carried out to fractionate an antigen of trichinella spiralis with sephadex g-50 and g-100. the specificty of the fractions has been followed up by means of the intradermal allergic reaction in six pigs, experimentally infected with trichenalla spiralis, one with trichocephalus suis and three, born by trichinellosis-affected sows. the second fraction has been tested also on four pigs, experimentally inoculated with ascaris suum, nine--with ascarsis suum and oesophagostomum and 1 ...197888790
role for activated macrophages in resistance against trichinella spiralis.to determine whether activated macrophages are important in resistance against the intestinal phase of nematode parasites, we studied trichinella spiralis infections in mice with normal macrophages and in mice with macrophages activated by either chronic toxoplasma gondii or acute listeria monocytogenes infections. the peak t. spiralis adult worm burden in the intestines of normal c57bl/6 or swiss webster mice occurred from 6 to 14 days after infection. subsequent expulsion of worms from the int ...197899366
effect of experimentally induced trichinellosis on the infection with erysipelothrix rhusiopathiae in rats.infection with erysipelothrix rhusiopathiae in rats infested 20 days earlier with trichinella spiralis developed more slowly, the clinical and pathoanatomic changes in the joints were expressed to a less extend, and the mortality rate was lower. the erythrocyte sedimentation rate, the precipitin formation and the phagocytic activity of the macrophages did not considerably change. experiments carried out to elucidate this fact did not reveal any antigenic or antagonistic relationships between par ...1978207030

foodborne hazards of microbial origin.foods can serve as vehicles of many pathogenic and toxigenic agents of disease. bacterial agents comprise three groups: 1) those that grow in the food and produce an active toxin before consumption (e.g., clostridium botulinium); 2) those that merely exist as contaminants in the food but are able to initiate infection when swallowed (e.g., salmonella spp.); and 3) those that multiply and produce large numbers of vegetative cells in the food, then release an active enterotoxin when they sporulate ...1978212326
trichinella spiralis: acceleration and inhibition of cyst calcification in rats.daily administration of vitamin d3 (75,000 iu/kg b. wt) for 7 days accelerated trichinella spiralis cyst calcification in rats with a 14-week-old infection. when disodium ethane-1-hydroxy-1, 1-diphosphonate (ehdp) was administered (50 mg/kg b. wt) from 2 days before until 2 days after vitamin d3 treatment, cyst calcification was inhibited. thus, the ability to inhibit e. spiralis calcification has demonstrated for the first time.1978215446

lymphocyte activation induced by trichinella spiralis infection reflected as spontaneous dna synthesis in vitro.spleen cells from mice, infected with trichinella spiralis, were cultured in micro and macrocultures without stimulatory agents. as controls, various polyclonal t and b cell activators were used. during the course of the infection the cells exhibited an increased spontaneous dna synthesis compared to the cells from uninfected controls. it was also found that the relative proportion of theta and ig-positive cells and macrophages was not significantly affected by the infection. to characterize the ...1979230926
physiological characterization of a biphasic immune response to trichinella spiralis in the rat.secondary infection with trichinella spiralis in the rat was associated with a host response that prevented approximately 80% of the total number of larvae recovered after primary infection from embedding in the intestine. the host response occurred within 15 min after contract of the parasite with intestinal mucosa and was not associated with acute inflammatory cell infiltrates or with the pathophysiology of the primary infection. eventual rejection of the residual population of embedded worms ...1979109546
mechanisms of killing of newborn larvae of trichinella spiralis by neutrophils and eosinophils. killing by generators of hydrogen peroxide in vitro.eosinophil and/or neutrophil leukocytes appear to have important roles in host defense against invasive, migratory helminth infestations, but the mechanisms of larval killing by leukocytes are uncertain. this study examines killing of newborn (migratory phase) larvae of trichinella spiralis during incubation with granule preparations of human eosinophils or neutrophils and generators of hydrogen peroxide (glucose-glucose oxidase) (g-go) or superoxide and hydrogen peroxide (xanthine-xanthine oxid ...197941002

t and b cells in the transfer of immunity against trichinella spiralis in mice.enriched populations of t or b cells, prepared by nylon wool filtration of mesenteric node lymphocytes from mice infected with trichinella spiralis, were capable of transferring immunity to normal and irradiated syngeneic mice. in cell recipients there was an early loss of fecundity by the worms and an accelerated expulsion from the intestine. treatment with anti-thy 1.2 serum, to deplete contaminating t cells, severely reduced or abolished the protective activity of enriched b-cell fractions. r ...1979313897
response of intestinal globule leucocytes in the mouse during a trichinella spiralis infection and its independence of intestinal mast cells.we have previously reported that intestinal mast cells represent a separate population of mast cells which is thymus- (t-) dependent. in this paper we examine whether the appearance of these cells is dependent on thymus-dependent antibodies or thymus serum factor(s). the response of intestinal mast cells and globule leucocytes to a trichinella spiralis infection was therefore studied in congenitally athymic (nude) mice after treatment with specific anti-t. spiralis hyperimmune serum or normal mo ...1979314302

migration of lymphoblasts to the small intestine. iii. strain differences and relationship to distribution and duration of trichinella spiralis infection.in nih strain mice, in which the majority of trichinella spiralis are located in the anterior half of the small intestine early in the enteral phase of infection, enhanced localization of mesenteric lymphoblasts, nylon wool separated mesenteric t-lymphoblasts and even oxazolone sensitized peripheral lymphoblasts is most prominent in the anterior region of the small intestine. as the worms move to the posterior half of the small intestine, enahnced localization of lymphoblasts is observed in that ...1979317031
trichiniasis among the animals in north eastern iran (1), 1969, 1976, 1977.in 1969, 1976 and 1977, 1,039 rodents and carnivores collected from north east iran were examined for trichinella spiralis. eighty four per cent of golden jackals, 30 per cent of red foxes and nine per dent of dogs were found to be infected. the importance of wild boar sus scrofa as the source of infection is discussed.1979318000
in vitro killing of schistosomula of schistosoma mansoni by bcg and c. parvum-activated macrophages.resistance to schistosoma mansoni infection in the mouse has been induced either specifically by a primary infection with this parasite or nonspecifically by a variety of immunostimulants such as bcg. in the present study we developed an in vitro system to examine the effector mechanism of nonspecifically induced resistance. activated macrophage monolayers obtained from bcg- or corynebacterium parvum treated mice killed a respective mean 32 +/- 6% and 48 +/- 5% of schistosomula after 24 hr incub ...1979376723
[diagnosis of trichinellosis and special aspects of a modified immunofluorescence test (author's transl)].trichinella spiralis was detected in 1835 by paget, an english student. since the introduction of the meat investigation law for trichinosis in 1937 the infection with this parasites became a rare condition. the last endemies in germany occurred in 1967 and 1977. they restimulated the discussion regarding the efficiency and sensitivity of the routinely used methods for the detection of tr. spiralis. 69 patients, suffering from infection with tr. spiralis were investigated using a modified ift. t ...1979396230
