Serological diagnosis of hydatidosis in abattoirs

Echinococcosis and hydatidosis are community health problems in different parts of the world. To study the efficacy of intra-dermal test in diagnosis of hydatidosis in cattle, hydatid fluid obtained from bovine and sheep liver and lung cysts was injected intra-dermal to animals. Skin reaction was recorded compared to control. Presence of the cyst in organs in postmortem examination of carcass was considered as gold standard. After 24 hours of injection, sensitivity and specificity of ID test in cows and sheep were calculated. On the ground of its merits, intra-dermal test may be used to diagnose infection before infected carcass enters the market.
