Risk factors contributing to fascioliasis endemicity in a focus in Dakahlia governorate 1- human host

ABSTRACT

Zoonotic fascioliasis is a problem not only in Dakahlia Governorate, but also in other Egyptian Governorates. Two hundreds and twenty patients randomly selected with suggesting manifestations were examined for fascioliasis. A total of 23 [10.4%] were positive by Kato thick smears, of which 21 were from Kafr El-Hessah and two from Oweish El-Hager. The proven human fascioliasis was examined for anti -Fasciola antibodies by IHAT and ELISA [Fhes], haemoglobin level, eosinophils percent, serum bilirubin and liver function tests. IHAT gave 82.61% positive results [19/23], and ELISA gave 100% positive results [23/23]. The clinical signs ranged between splenomegaly and ascitis in 4.34% for each up to hepatomegaly in 73.91% and mild fever in 78.26% but 2 cases were asymptomatic. Mild eosinophilia and moderate anaemia were recorded with means of 11 +/- 5.8 and 10 +/- 1.3 respectively. Mean serum bilirubin was not elevated [0.91 +/- 0.51 gm/dl]. Liver function tests [AST within normal range in all cases; <40 unit /ml but one patient had ALT above normal; >45 unit/ml]
