detection of circulating toxocaral antigens in dogs by sandwich enzyme-immunoassay.	this study describes the presence of circulating toxocaral antigens (cta) in the sera of dogs infected with toxocara canis (t. canis) by using a sandwich enzyme-immunoassay (seia). a specificity of this assay with different antigens was observed, i.e. the eia values, which express the antigen concentration, of excretory-secretory antigen from t. canis larvae were higher than those of other antigens (ascaris lumbricoides, dirofilaria immitis and fasciola hepatica). the variability in intra-assay ...	1984	6365746
hemoimmuno-adherence test (hiat) for the detection of antibodies anti-toxocara canis l2 larvae.	the use of a hemoimmuno-adherence test (hiat) for detecting antibodies anti-l2 larvae of toxocara canis is presented. the hiat allows to reveal the presence of antibodies in the sera of both naturally and experimentally infected animals. the sensitivity of hiat appears to be comparable to that of methods such as immunoenzymatic ones.	1983	6399735
purification and characterization of excretory and secretory antigen of toxocara canis larvae.	excretory/secretory (es) antigen of toxocara canis larvae was isolated from the culture medium of second-stage larvae by gel filtration. the antigen induced production of not only igm or igg but also ige antibody. the antigen, when treated with guanidine hydrochloride and 2-mercaptoethanol, lost its allergenic activity but retained an ability to induce igm or igg antibody. purified antigen was of glycoprotein nature and had a molecular weight of 35,000. the whole antigen showed a cross-reaction ...	1983	6411609
interrelationship of eosinophilia and ige antibody production to larval es antigen in toxocara canis infected mice.	in order to elucidate the relationship between eosinophilia and ige antibody production in parasitic infection, the degree of eosinophilia and ige antibody levels to larval es antigen of toxocara canis were investigated in eight inbred strains of mice after infection with t. canis. eosinophilia was far higher in degree in sjl mice than in the other inbred strains. however, ige antibody levels to larval es antigen in sjl mice were the lowest among those inbred strains. similarly, the degree of eo ...	1984	6438599

effect of thiabendazole on the migration of toxocara canis larvae in the mouse.	the effects of thiabendazole on the survival and migration of toxocara canis larvae in mice were studied. although thiabendazole had a negligible larvicidal effect, it produced marked inhibition of the migration of the larvae in tissues. larvae were arrested in the liver after oral inoculation and in the lungs after intravenous inoculation. observations indicated that the drug may have a reversible, as well as a progressive, time-related metabolic effect on the larvae. significant inhibition of ...	1984	6470886
[retinoblastoma--clinical diagnostic errors].	the author discusses clinical and histological findings in 6 patients whose complaints had been wrongly diagnosed, out of 91 patients in whom a retinoblastoma had been diagnosed at the ophthalmo-pathological laboratory of the university eye hospital in utrecht between 1960 and 1981. in 6 other cases the diagnosis was doubtful. all the cases occurred before 1974. the faulty diagnoses were: spontaneously necrotized retinoblastoma, congenital anomaly, retinal detachment, infection with toxocara can ...	1984	6482302
immunoradiometric assay for quantitation of dirofilaria immitis antigen in dogs with heartworm infections.	an immunoradiometric assay (irma) was developed, optimized, and validated for detection of parasite-specific antigen in sera from hosts with filarial infections, using dirofilaria immitis in dogs as a model. the precision, reproducibility, and parallelism of the irma were examined, using precision profile analysis. the irma had acceptable precision and reproducibility [less than 15% intra-assay coefficient of variation (cv)] over a working range of 10 to 2,000 ng of d immitis-antigen (ag)/ml. th ...	1984	6497105
a five-year analysis of diseases of dogs and cats in the veterinary clinic of freetown, sierra leone.	a survey is presented of the diagnoses found in 2938 dogs and 32 cats, treated between january 1976 and january 1980 at the veterinary clinic of freetown. more than one third of the dogs (1175) and 13 cats were infected by ancylostoma spp., whereas toxocara canis and toxascaris leonina were encountered in 236 and 232 dogs, respectively. noteworthy is also the relatively high figure of 12 dogs affected by negri bodies (rabies). it is pointed out that dogs and cats move about fairly freely in the ...	1984	6508729
[visceral larva migrans in childhood: report of 2 cases].	reports of visceral larva migrans (vlm) are not frequent in brazil, but the prevalence of this disease may be more common due to poor environmental conditions to which most of the children are exposed. the most common infectious agent is toxocara canis, a parasite of the intestinal tract of dogs. children get infected eating contaminated material with feces of dogs. the ova are swallowed and reach the intestinal lumen of the children. systemic migration occurs by lymphatic or portal circulation ...	1984	6517736
repeated patent infection of adult dogs with toxocara canis.	three adult male greyhounds have been repeatedly infected with toxocara canis by oral administration of 100 to 200 infective ova. each infection has become patent as shown by the presence of eggs in faeces. anthelmintic treatment between 7 and 14 weeks after infection yielded an average of 25% of the inoculum as adult worms. these dogs have continued to be fully susceptible to infection despite repeated exposure to this parasite, and despite the presence of serum antibody to both parasite surfac ...	1984	6520377
haematological and serological data from dogs raised worm-free and monospecifically infected with helminths.	pups free from helminth infection were obtained by treating the bitch prior to parturition, and the bitch and her pups after whelping, with oxfendazole and praziquantel. they were then housed in an area free from contamination with helminth eggs. freedom from infection was confirmed by necropsy examinations and by serological tests using the enzyme linked immunosorbent assay (elisa). groups of pups were infected with toxocara canis, echinococcus granulosus, taenia ovis, t. pisiformis and t. hyda ...	1984	6525114
prevalence of toxocariasis and echinococcosis among dogs in the niger delta.	a sample of 60 dogs in the port harcourt area of the niger delta was examined for intestinal parasites. the high prevalence rates of toxocara canis (56.6%) and echinococcus granulosus (85.0%) in the area are discussed in relation to public health. other parasites found in dogs include toxascaris leonina (3.3%), uncinaria stenocephala (70.0%), dipylidium caninum (88.3%), trichuris vulpis (56.7%), ancylostoma caninum (65.0%) and taenia hydatigenia (43.3%).	1984	6530709
visceral larva migrans: a risk assessment in baton rouge, louisiana.	visceral larva migrans, vlm, is a disease of young children. due to lack of awareness of the disease as well as its non-specific symptomology, a survey of the potential risk of acquiring the disease was conducted in the baton rouge, louisiana area. the greatest number of dogs showing positive results to tests for the presence of the eggs of toxocara canis were those less than one year of age. very few of the soil samples collected from twenty different parks/playgrounds were found to contain egg ...	1984	6534905
experimental toxocariasis in mice and its effect on their behaviour.	when compared to uninfected controls, mice infected with second-stage larvae of toxocara canis exhibited: (1) impaired motor performance, (2) increased ambulatory activity, (3) a greater relative preference for more exposed areas and (4) a greater overall preference for novel environments. the infected mice also appeared to show less approach-avoidance conflict and seemed less cautious when presented with novel stimuli. these behavioural differences were independent of measures of general health ...	1984	6540073
[mouse strain difference in visceral larva migrans of toxocara canis].	the mode of larval migration (visceral larva migrans) in toxocara canis infection was compared for balb/c, c57bl/6, c3h/he, dba/2, nc and balb/c nude mice following oral infection with 400 eggs. the mean recovery of larvae from the liver on day 2 post infection (pi) was not different in terms of the strain, age or sex of the mice. the number of larvae recovered from the liver decreased in all strains on days 6, 12 and 21 pi, but the mean for balb/c and (nc x balb/c) f1 mice was significantly hig ...	1984	6542020
prevalence and survival of toxocara canis eggs in the urban environment of perth, australia.	using a technique of proven efficiency no toxocara canis eggs were recovered from a total of 266 sand samples collected from "dog beaches" and parks in the perth urban area. this observation emphasises that the major risk to humans is from an environment in which puppies are found. other observations, made at a heavily contaminated site, showed that the eggs of t. canis disappeared from sandy soil over about 6 months during a period in which it would have been expected that conditions were favou ...	1984	6542727
the migration of larval toxocara canis in mice. i. migration through the intestine in primary infections.	toxocara canis second stage larvae (l2) hatched in the stomach of mice and within 2 h reached all parts of the small intestine, the posterior half being the preferred site for larval penetration. following penetration at the base of crypts of leiberkuhn they followed tortuous routes in the lamina propria, and entered the tunica muscularis obliquely. larvae only appeared to be arrested in their migration in the submucosa and lamina propria by an inflammatory reaction composed mainly of lymphocyte ...	1984	6543062
the migration of larval toxocara canis in mice. ii. post-intestinal migration in primary infections.	following oral infection of nih mice with toxocara canis embryonated eggs the l2 pass the visceral phase of migration during te first week of infection. larvae reach the liver and lungs and peak in number in these organs 2 and 3 days after infection, respectively. larvae are then dispersed throughout the body and enter the myotropic--neurotropic phase by the 7th day of infection. larvae injected directly into the brain are capable of migrating into the viscera and musculature. considerable patho ...	1984	6543063
antibody responses to toxocara canis using sera from parasite-infected mice and protection from toxocariasis by immunisation with es antigens.	evidence for serological cross-reactions between toxocara canis and related nematode parasites has been sought using sera from infected mice and the immunodiagnostic excretory/secretory (es) antigen of t. canis larvae. sera from mice experimentally infected with either t. canis, t. cati, t. pteropodis, toxascaris leonina or ascaris suum were tested for the presence of antibodies to t. canis es antigen by solid-phase radioimmunoassay (ria) or enzyme-linked immunosorbent assay (elisa) using anti-m ...	1984	6543490
anthelmintic effect of levamisole, ivermectin, albendazole and fenbendazole on larval toxocara canis infection in mice.	the anthelmintic effects of levamisole (100-50 mg kg-1 live bodyweight), ivermectin (2 mg kg-1 bodyweight), albendazole and fenbendazole (both 100 mg kg-1 bodyweight), were tested against second stage toxocara canis larvae in mice. anthelmintic treatment on days 2 to 7 after infection inclusive resulted in significant (p less than 0.05) retention of larvae in the liver, and fewer larvae migrated subsequently to the brain and the musculature of treated mice compared to untreated controls. most of ...	1984	6546805
toxocariasis: a neglected entity.	toxocara canis infects many dogs yet has been seldom implicated as a cause of human disease in new zealand. nine patients with diagnostic titres for toxocara canis who were seen in christchurch hospital over a five-year period are described. ophthalmoscopic signs of toxocaral infection were visible at the optic disc or posterior pole of all ten affected eyes. a localised disciform detachment of the macula or a focal granuloma on the disc or retina were the commonest lesions. vision was reduced t ...	1983	6578425
comparison of counterimmunoelectrophoresis with indirect haemagglutination test in the detection of antibodies in rabbits experimentally infected with various species of ascarids.	counterimmunoelectrophoresis (ciep) and indirect haemagglutination (iha) were used for the detection of antibodies in 437 sera of rabbits experimentally infected with ascaris suum, toxocara canis and toxascaris leonina. ciep showed 44.0-52.3% positivity in a. suum, 25.5% in t. canis and 19.7-29.2% in t. leonina infection, whereas the positivity detected by iha was 59.8-90.2% in a. suum, 44.8% in t. canis and 59.6% in t. leonina infection. a comparison of the two tests reveals that ciep is a suit ...	1984	6589203
trapping of large numbers of larvae in the livers of toxocara canis-reinfected mice.	congenitally athymic nude mice (balb/c-nu/nu) and balb/c-nu/+ were infected with 500 embryonated toxocara canis eggs. six weeks later they were reinfected with the same number of eggs. the liver and other organs were examined for numbers of 2nd-stage larvae at 2, 4, and 6 weeks after reinfection. far more larvae were trapped in the liver after reinfection than after the primary infection but fewer were found in the livers of balb/c-nu/nu than in balb/c-nu/+ mice.	1983	6603485
