EFFECT OF TOXOCARA CANIS SECOND STAGE LARVAE ON THE HOST IMMUNE SYSTEM
We have studied functional alteration of immunocytes in mice following inoculation of Toxocara canis second stage larvae. Results indicated depression of lymphocyte blastogenesis in response to concanavalin-A, phytohemagglutinin and allogeneic non B-cells; however, B-cell polyclonal activation was not affected as indicated by the production of total IgG. In contrast, frequency of antibody ...
متن کاملProteinases in Excretory-Secretory Products of Toxocara canis Second-Stage Larvae: Zymography and Modeling Insights
Components released in excretory-secretory products of Toxocara canis larvae (TES) include phosphatidylethanolamine-binding proteins (TES26), mucins (TES120, MUC2-5), and C-type lectins (TES32, TES70) and their biochemical, immunological, and diagnostic properties have been extensively studied albeit proteinase activities towards physiological substrates are almost unknown. Proteolytic activiti...
متن کاملInhibitory effect of isoquinoline alkaloids on movement of second-stage larvae of Toxocara canis.
To find new anthelmintics against parasites living in host tissues, we used an in vitro assay to screen isoquinoline alkaloids for nematocidal activity on the larva of dog roundworm, Toxocara canis. To evaluate the efficacy of anthelmintics in vitro, Tsuda et al. previously introduced the concept of Relative Mobility (RM) of Toxocara larvae. After improvement of the assay system using image dat...
متن کاملcomparison of excretory secretory antigens of ascaris lumbricoldes and toxocara cati 2nd. stage larvae with biochemical methodes
purification of parasitic antigens is a major activity in immunoparasitology because of its application in immunodiagnosis, vaccination analysis of immunopathology, preparation of monocolomal antibody and finding out the cross reactive antigens versus specific antigens of a parasite. in this survey f2 ultrafiltration excretory secretory antigens of ascaris lumbricoides and toxocara cati were se...
متن کاملAngiostrongylus cantonensis (Nematode: Metastrongiloidea): In Vitro Cultivation of Infective Third-Stage Larvae to Fourth-Stage Larvae
The present study to attempt to cultivate Angiostrongylus cantonensis from third-stage larvae (AcL3) to fourth-stage larvae (AcL4) in vitro in defined complete culture medium that contained with Minimum Essential Medium Eagle (MEM), supplemented amino acid (AA), amine (AM), fatty acid (FA), carbohydrate (CA) and 20% fetal calf serum (FCS) was successful. When AcL3 were cultured in the defined c...
