seroprevalence of toxoplasma gondii in rodents from various locations in peninsular malaysia.numerous studies have reported the prevalence of toxoplasmosis among malaysians and various domestic animals; but there is paucity of information on its prevalence among rodents which could potentially contribute to the transmission of toxoplasma gondii in both domestic and sylvatic fauna. five hundred twenty-six rodents were captured from six locations in malaysia and identified to species. serum samples were collected from these rodents and tested for t.gondii antibodies using an immunofluores ...201526521512
dot enzyme-linked immunosorbent assay (elisa) for the detection of toxocara infection using a rat model.toxocariasis is a zoonotic disease usually caused by dog and cat roundworms, toxocara canis and t. cati. detection and diagnosis is difficult in paratenic and accidental hosts, including humans, as they cannot be detected through conventional methods such as fecal examination. diagnosis therefore relies on immunological methods and molecular methods such as enzyme-linked immunosorbent assay (elisa) and western blot, which are both time-consuming and requires sophisticated equipment. in the phili ...201729114122
