Blood samples were tested by serum ELISA and Fasciola-antibodies
were detected in two samples. LTE were not observed in these two samples via Kato-Katz or FECT. Subsequently,the two positive sample swere retested by IFAT, which yielded negative
test results. Considering the negative IFAT results,the two positive samples and those samples with a critical (close to positive)value after the first serum ELISA were retested with a helminth screening ELISA. No Fasciola-antibodies were detected with this test.
