AI Article Synopsis

  • The study focused on understanding the immune response to Toxocara canis in patients with visceral larval toxocarosis by measuring specific IgG and IgE levels using the ELISA technique.
  • By isolating immunoglobulin fractions, researchers found that removing IgG led to increased levels of IgE, supporting the idea that IgG can inhibit IgE responses.
  • The results showed a weak correlation between IgG and IgE levels in the serum of symptomatic patients, indicating a complex immune response to the parasite.

Article Abstract

The aim of the study was to characterize the antiparasite humoral response in patients with the syndrome of visceral larval toxocarosis. Specific IgG, specific IgE and total IgE immunoglobulins against Toxocara canis excretory/secretory antigens (TES) were detected by using ELISA technique. Antibody response was studied in complete sera as well as in immunoglobulin fractions (IgG and IgE), isolation of which was performed on Protein A Sepharose. It was observed that removal of IgG from the serum samples resulted mostly in increasing levels of anti-Toxocara IgE antibodies what agrees with the theory of the blocking effect of IgG in the immune response. The results demonstrated a little correlation between slgG and slgE in the sera of symptomatic patients, examined in ELISA reaction.

Purpose: In the present study, the effects of leaf and rhizome extracts of Arum rupicola Boiss rupicola were searched on the infective stage Toxocara canis larvae (L3) in the experimentally infected mice.

Methods: Four-six week-old male BALB/c mice were divided into eight groups (G1-8, each group consisted of 7 mice), and they were infected orally with 500 T. canis eggs with L3.

Thiazoles serve as pharmacophores in many molecules that exhibit significant biological activity. This study used in vitro assays and in silico methodologies to identify novel medication candidates for preclinical evaluation of visceral toxocariasis treatment. The objective was to assess the impact of 11 thiazolohydrazone derivative compounds on the larval eggs of Toxocara canis.

Background: is a known cause of a zoonotic infectious illness called toxocariasis. Parathenic hosts are important as they can transmit larvae 2 (L) through direct transmission. Scanning electron microscope (SEM) techniques are needed to provide a three-dimensional image of each stage of larvae.

One neglected zoonotic illness is toxocariasis. There are not enough anthelmintic drugs in the market to treat low-effectiveness toxocariasis against migrating larvae. Therefore, it is critical to find new, safe alternatives to toxocariasis treatment today.

Toxocara canis and Toxocara cati are parasitic nematodes in the order Ascaridida, which inhabit the small intestines of dogs and cats, respectively, as adults. Although often nonpathogenic as adults, nematodes within this genus are capable of causing widespread disease throughout the host while in a larval stage, during which time larvae migrate throughout the body in a process termed larva migrans. Larvae are also capable of surviving within host tissues in an encysted arrested stage, without immune clearance by the host.
