*AE/CE indicates the test is specific only to genus level. AE, alveolar echinococcosis; CE, cystic echinococcosis; neg, negative; WB, Western blot. †ELISA-negative serum only.
‡Not every patient for whom echinococcosis was diagnosed by ultrasound had inconclusive results or a history of echinococcosis provided a blood sample. For some of these patients, insufficient serum was available from the blood sample to undertake both ELISA and WB.
§E. granulosus hydatid fluid and/or native protoscolex antigens and/or antigen B positive but Em18 and EmG11 negative.
¶Em18 and/or EmG11 positive (E. granulosus hydatid fluid and/or native protoscolex antigens and/or antigen B positive or negative).
#Diagnosis confirmed by PCR and/or histology of resected lesion.
