An enzyme-linked immunoelectrotransfer blot (EITB) is developed for immunodiagnosing human neurocysticercosis. The assay's efficacy is evaluated in 71 neurocysticercotic patients whose diagnosis of the disease and evaluation of disease activity is based on CT scan findings. We identified eight bands (molecular weigh less than 35 000) that evaluate the disease activity: active disease, calcification in progress, inactive disease. All samples patients with active disease recognized 14 000 band. This band is missing in the others parasitic diseases and in serum of the patients with inactive diseases or calcification in progress. The enzyme-linked immunoelectrotransfer blot is simple to perform and may be used in sero-epidemiology.

Enzyme-linked immunoelectrotransfer blot (EITB) detects antibodies against seven larvae antigens in three protein families (GP50, T24/42, and 8-kDa) with different structures and functions. EITB banding patterns against these antigens in pigs provide information about the course of infection and may discriminate viable cysticercosis. We analyzed the banding patterns and infection outcomes (presence of viable cysts, degenerated cysts, and any cysts) of 512 rural pigs.

Neurocysticercosis (NCC) is the most common helminthic infection of the human central nervous system. The antibody detection assay of choice is the enzyme-linked immunoelectrotransfer blot assay using lentil-lectin purified parasite antigens (LLGP-EITB, Western blot), an immunoassay with exceptional performance in clinical samples. However, its use is mainly restricted to a few research laboratories because the assay is labor-intensive and requires sophisticated equipment, expertise, and large amounts of parasite material for preparation of reagents.

Background: Neurocysticercosis, caused by the larval stage of , affects the cerebral ventricles in 20-30% of cases and may lead to hydrocephalus and other neurological morbidity. Conventional treatment for cysts in the 4th ventricle includes open surgery (suboccipital approach) and neuroendoscopy, with the latter being the option of choice. Stereotactic surgery, minimally invasive, offers a good alternative for this type of deep lesion.
