Use of the ELISA (Em2-Em18) and Western Blotting Methods on Diagnosis of Alveolar Echinococcosis

Objective: Alveolar echinococcosis (AE) is one of the most lethal parasitic zoonoses in the Northern Hemisphere, and early serological detection is important to start treatment and to improve survival. A total of 50 sera samples of patients diagnosed as having various diseases were examined for by two different serological diagnostic methods. Methods: Em2-Em18 ELISA (Bordier Affinity Products, Crissier, Switzerland) and Echinococcus Western Blot immünoglobulin G (IgG) (LDBIO Diagnostics, Lyon, France) were used for analyisis. Results: Western Blot IgG test, used as a confirmatory test, showed IgG antibody in 85.7% (18/21) of patients with CE, while all serum samples of 10 patients with AE were evaluated as positive. This method yielded an incorrect diagnosis in the patient with chronic hepatitis and in the patient with granulomatous inflammation with caseification. Samples taken from patients with liver-related diseases and other parasitic-related diseases were found to be negative. Conclusion: The serological methods used in the study were found to be important in the early diagnosis of alveolar echinococcosis in the endemic areas, since it could be used in sero-epidemiological studies.
