Toxocariasis is a neglected and geographically widespread parasitic disease. The detection of specific antibodies associated with this disease is required to confirm its clinical diagnosis and to aid in prevention. Although helminth infection during pregnancy can promote foetal immune responses with long-term effects, specific information regarding the risk of Toxocara spp. infection to the human foetus during pregnancy is lacking.Therefore,the present study aimed to investigate the frequency of antibodies against Toxocara spp...

Toxocariasis is a parasitic infection caused by the roundworms Toxocara canis or Toxocara cati, mostly due to accidental ingestion of embryonated eggs. Clinical manifestations vary and are classified according to the organs affected. Central nervous system involvement is an unusual complication. Here, we report two cases with neurological manifestations, in which there was cerebrospinal fluid (CSF) eosinophilia with marked blood eosinophilia and a positive serology for Toxocara both in serum and CSF. Improvement of signs and symptoms after specific treatment was observed in the two cases...

Toxocara vitulorum is an ascarid that is frequently found in sub-tropical regions but little is known about infections in more temperate climates. In this study, we report the occurrence of this parasite in a beef cattle herd in eastern Germany. In June 2016, large (14-20 cm) cream-colored worms identified as adult T. vitulorum were observed in the feces of 2- to 3-month-old calves. Eggs of this parasite were subsequently detected in pooled fecal samples collected on all three farm sites. The morphological identification was supported by analysis of partial cytochrome c oxidase I and internal transcribed spacer 1 gene sequences...
