The cross-linkages contained within the proteinaceous opercular cement seal holding the egg operculum of Fasciola gigantica solubilised in 0.1N saturated NaOH, concentrated HCl, H2SO4 and H3PO4, whereas the quinone tanned eggshell solubilised only in concentrated HNO3 and NaOCl. In TCA, H3BO3 and CH3COOH, the cross linkages of proteinaceous opercular cement and the quinone tanned eggshell remained unaffected. This study has shown that the cross linkages of the opercular cement, the operculum and the quinone-tanned eggshell differ in their permeability and solubility properties.Keywords

Fasciolosis disease is caused by the most common species Fasciola hepatica and Fasciola gigantica. Surface topography and some of the important features of morphology of the Indian F. gigantica has not yet been described and therefore, the present study was elucidated about the important structural surface topography features of the F. gigantica. Adult flukes of F. gigantica are flattened and leaf-like in shape and measures approximately 5-6 cm in length, with narrowed anterior and posterior ends and are the presence of uneven surface with alternating surface folds armed with spines. At the anterior end the oral sucker occurs at its tip while the ventral sucker is present at the oral cone-main body junction, they are used to grip the lining of the bile duct of the liver of Bubalus bubalis and to assist in the movements of the fluke and the spines are absent around the suckers. The common genital opening for the male and female reproductive systems genital pore which is present just anterior to the ventral sucker. The posterior tip of the body has a prominent excretory pore first time reported with very few spines are present at the posterior end of the body and hence appear smooth.Keywords
