The aim of the study was to enhance specificity of immunological diagnosis in toxocarosis. The investigations concem: detection of circulating parasite antigens using dot-ELISA technique and detection of specific IgG antigodies using ELISA test with low molecular weight (≤30 kD) excretory-secretory (ES) larval T. canis antigens. The circulating antigens were investigated in 60 sera and 20 anterior chamber fluids from children with ocular form of toxocarosis. These antigens were present only in 3 sera and 2 anterior chamber fluids in children with active intraocular inflamation and fluid antibodies titers 1:5120 and 1:20000. Comparative study with different ELISA tests indicated that use of low molecular weight antigens increase specificity of reaction.

Toksokaroza w regionie lodzkim w latach 1996-2000

In the paper epidemiologic analysis of toxocarosis with socio-medical background in humans in the Łódź macroregion over the years 1996-2000 was carried out. It was found that 58.2% of toxocarosis cases represent asymptomatic invasions occurring more often in town residents. The clinical form "minor" pertained the country residents, patients of elementary education and the group "pupil-student". The "major" form of toxocarosis was found in the country residents, young people, and patients over 60 years old.
Mice were infected with Toxocara canis by an oral administration of embryonated eggs of the parasite, then they were killed between 1st and 8th week after infection to obtain sera and splenic lymphocytes. The lymphocytes were kept in culture medium for 3 to 6 days with either concanavalin A or excretory-secretory antigen of T. canis and assayed for proliferative responses. The obtained sera were examined for the presence of specific IgG and IgM antibodies. It was found that cell-mediated immunity was depressed for 3 weeks after infection and the first signs of the developing immunity were detected only at the 4th week of infection. Subsequently, the blastogenic responses increased reaching a level significantly higher when compared with those of the control cultures at 8th week of infection. Specific toxocaral IgG and IgM antibodies were first detected in the samples collected at the 4th week.
Pneumocystosis (Pneumocystis carinii pneumonia) is a parasitic disease which in Lithuania used to be diagnosed only with the use of pathohistological methods. The aim of our study was to determine prevalence of P. carinii antibodies among children and women, using immunochemical method (ELISA) and to find out which groups of patients have higher antibody titres. We also addressed the question of infection with P. carinii among rodents. After investigating 9 species of rodents it was found that mostly infected is brown rat (Rattus norvegicus) - 42.9% of them were found infected. The least infected was bank vole (Clethrionomys glareous)- 5.9. %. The brown rat lives on hatch of domestic birds, rabbits or drinks eggs, while rodents in nature live on insects, molluscs, amphibians etc. European water voles (Arvicola terrestris) and field voles (Microtus arvalis) are vegetable feeders. Our data shows that those species of rodents were not infected with pneumocysts.

Infekcje Toxocara w swietle materialow wlasnych

Toxocarosis clinical forms wers diagnosed according to KRAUS et al. (1995). There were three forms: l) asymptomatic - marked by hypereosynophilia and ELISA positive serologic reaction, 2) minor - with cutaneous, pulmomary and pseudorheumatic lesions, 3) major – with hepatosplenomegaly and multifocal inflammatory lesions of organ or sight. Over the years of 1994-1997 in Infectious, Parasitic and Tropical Diseases clinic of the Voivodship Specialist Hospital of Łódź we found and treated 137 Toxocara canis cases. Among them 63 (46.0%) asymptomatic, 57 (42.6%) minor and 17 (12.4%) major forms were diagnosed. The disease was detected in 80 (58.4%) adults and 57 (41.6%) children. Seventy six patients lived i towns and 61 in country. Minor form patients had the symptoms as follows: skin allergy, large joints lesions, augmentation in lymph nodes. Radiology examinations revealed pulmonary lesions. Using ultrasonography there was found hepatosplenomegaly and changes echogenity in patiems with major form. Biochemical tests showed elevation in hepatic enzymes activity. Lesions of organ of sight were multifocal and usually included uveitis, retinitis, inflammation of anterior chamber and inflammation of vitreous body.

Problem toksokarozy na Litwie

Human infection with a parasite called larva migrans visceralis (most often larva of Toxocara canis) has been poorly studied. In order to determine the extensity of infection in dogs, stray dogs at the age more than 1 year were studied. During section, the worms were found in 16 (11.3%) dogs, at the intensity of infection 2-12 specimens per dog, mean value 5.7. To estimate the extent of infection of soil through dog feces, and to find ways and vectors of toxocarosis, soil samples were studied, taken from house gardens, parks, lawns and places of children play. The eggs of T. canis were found in 7.3% samples. The soil from house gardens was infected in 8.1%, that from the places of children play – in 5.7%. The eggs of T. canis were most often found in samples collected in summer-autumn. Patients with clinical symptoms suggesting presence of larvae migrans visceralis were immunologically tested. Blood of 739 patients with various alergy symptoms or unclear ethiology was examined. The reaction was positive in 11,5% persons, most of them children at the age of 1-3 years. In 21 children aged 1 or less the titre was high. Because the children below 1 have a limited contact with soil, a possibility of passive infection through the placenta was considered. Using ELISA test, 100 pregnant women, and children during the first year of their life were examined. Antibodies against T. canis were found in 21 women (4.7%). During the birth, the antibodies were found in blood of one child only.
Rabbits were infected with an oral dose of 50000 eggs of Toxocara canis or with an intracarotid injection of the second stage larvae of the parasite in order to develop ocular toxocariasis. Serum and ocular fluid samples were collected from the rabbits after 1,3 and 6 months after infection and examined for specific toxocaral antibodies and circulating parasitc antigen. Furthermore, an ophthalmoscopic examination was performed at the time of sampling. None of the infected animals showed the signs of ocular involvement, however, toxocaral IgG antibodies and circulating parasite antigen were present in the anterior chamber fluid samples.
