Parasitol Res (2012) 110:2187–2191 Chagas disease and human cysticercosis, both of which are considered to be neglected tropical illnesses and occur in poor rural communities of low-income countries in Latin America (Bethony et al. 2011). At present, T. solium antigens for diagnosis of human cysticercosis are derived from parasites extracted from infected pork (Deckers and Dorny 2010). Perhaps recombi- nant antigens can serve as a simplified, low-cost substitute for the native antigens, and also provide a reproducible, field-applicable diagnostic assay (Scheel et al. 2005). The immunodot blot Tsol-p27 test showed good sensitivity and specificity in our study, and it is simpler to perform and less expensive than ELISA, EITB, and Western blot. Moreover, immunodot blot Tsol-p27 does not require a spectrophotom- eter to read the results or electrophoresis and transfer equip- ment to absorb the antigen onto nitrocellulose membranes (Plancarte et al. 1994). It is plausible that this test will prove to be the serodiagnostic method of choice for use in the field or in poorly equipped laboratories in endemic countries.
