“…Soluble WWA preparations of S. mansoni at a concentration of 250 ng/dot were also reported to yield false positive results in malaria and filaria positive human subjects (Montenegro et al 1999). Noya et al (2002) had also observed false positive reactions in western blot and ELISA with crude WWA and egg antigens of S. mansoni particularly in individuals infected with nematodes, though these antigens possessed high sensitivity for the diagnosis of infection. In the present study S. spindale ESA had not exhibited cross reaction with amphistome positive sera in Dot-ELISA.…”

“…For instance, in seroepidemiological surveys, apart from test procedures, sample collection and processing are sometimes cumbersome and require trained personnel for venopuncture and separation of serum samples under field conditions. Besides that, venopuncture is not widely accepted, especially by children and certain ethnic and religious groups (Noya et al, 2002). For field-based diagnosis and follow-up of chemotherapy of schistosomiasis, there is urgent need for simple and reliable tests, which are applicable in endemic areas (van Lieshout et al, 1992(van Lieshout et al, , 2000Chitsulo et al, 2004).…”

“…For field work, the whole population can be screened though ELISA-SEA-SMP or APIA. Then, Kato-Katz, and COPT would be applied only to the positives as proposed by Noya et al (2002). An exam with the advantages of the ELISA-like test that discriminates active from past infection would be very useful when evaluation of the impact of treatment is the goal.…”

“…Based on the fact that morbidity studies in these areas really do not help too much, laboratorial markers of active infection have been taken into consideration to define cases of schistosomiasis. We have proposed three categories (Alarcón de Noya et al 2002):…”
