Toxocarosis and paratenic hosts

ABSTRACT

The seroprevalence rates of human toxocarosis figured up to 24.5% versus Toxocara canis and 22.1% versus Toxocara vitulorum in some selected localities in Egypt, using enzyme linked immunosorbent assay technique. Toxocara vitulorum larvae in experimentally infected mice and rats follow the same manner of migration previously described for T.canis with more adaptation to mice than rats as paratenic host. This study clarifies the role of rodents in maintaining Toxocara larvae and spread of infection to other host
