background: human toxocariasis, a helminthozoonosis, is due to the migration of toxocara species larvae into human organisms. humans, especially children become infected by ingesting of embryonated eggs from soil, dirty hands, and raw vegetables. seroprevalence of this infection is high in developed countries, especially in rural areas. the aim of this study was to investigate the seroepidemiol...

Various serological techniques including immunoprecipitation, indirect haemagglutination and the indirect fluorescence antibody test have been successfully applied for the detection of fasciolosis, mainly in experimental infections. Recently, the most frequently used assay is the ELISA technique with somatic or excretory-secretory antigens obtained from adult flukes. Further purification of suc...

In order to improve the specificity and sensitivity of the techniques for the human anisakidosis diagnosis, a method of affinity chromatography for the purification of species-specific antigens from Anisakis simplex third-stage larvae (L3) has been developed. New Zealand rabbits were immunized with A. simplex or Ascaris suum antigens or inoculated with Toxocara canis embryonated eggs. The IgG s...

Toxocara canis is a parasitic nematode that infects canines worldwide, and as a consequence of the widespread environmental dissemination of its ova in host faeces, other abnormal hosts including mice and humans are exposed to infection. In such abnormal or paratenic hosts, the immature third-stage larvae undergo a somatic migration through the organs of the body but fail to reach maturity as a...

b ackground: we tried to investigate the hair contamination of pet dogs and farm sheepdog with toxocara eggs in terms of the different sex and age groups in north-west of iran (urmia and its sub- urbs). m ethods: hair samples were collected from a total of 138 pet and farm sheepdogs from november 2008 to june 2009 in urmia city and the suburb (west azerbaijan-iran) and examined for the pres- en...

background: toxocariasis is an important disease caused by the larvae of parasitic worms such as toxocara canis and t. cati . public parks can be the source of toxocariasis for small children. this survey was conducted to de-termine the prevalence of toxocara spp. ova in parks of mashhad and khaf northeastern iran. methods: in this descriptive cross-sectional study, performed in november 2011 t...
