  ABSTRACT: Rapid enzyme linked immunosorbent assay (ELISA) was compared with the standard ELISA and indirect haemagglutination (IHA) techniques for the diagnosis of human hydatidosis. Eighty nine serum samples including 17 from hydatidosis patients (10 surgically confirmed and 7 clinically suspected), 50 from patients with other parasitic diseases and 22 samples from normal healthy individuals were analysed for anti-hydatid IgG antibodies using sheep hydatid cyst fluid antigen. The sensitivity and specificity respectively was found to be 82.3 and 100 per cent by rapid ELISA; 88.23 and 90.27 per cent by standard ELISA and 70.58 and 100 per cent by IHA technique. No cross reactions were observed with rapid ELISA technique using samples from cysticercosis and amoebiasis patients and normal healthy controls. The present study indicates that rapid ELISA can easily be performed in place of the standard ELISA for the serodiagnosis of human hydatidosis with the advantage of minimising reporting time and manpower hours.

  ABSTRACT: Cysticercosis, a disease of economic and public health importance, is caused by Cysticercus cellulosae, the metacestode stage of Taenia solium. Experimental induction of cysticercosis was achieved in young pigs by feeding an optimum dose of 20,000 T. solium (Indian strain) eggs after immunosuppression, to assess the effect of albendazole and development of the immune response to cysticercus antigens before and after treatment. Histopathological studies revealed the presence of cysticerei in liver, lungs and muscles. Treatment with albendazole at 15 mg kg-1 body weight daily for 30 days starting from day 0 or 15 days post-infection resulted in 100% cure rates. Increases in antibody titre to crude soluble extract and a Sephadek G-200 purified antigenic fraction of Cysticercus cellulosae were found on days 25, 40 and 55 post-infection in untreated pigs and those in which treatment started on day 15 post-infection, whereas no increase in antibody response was observed in pigs in which treatment started on day 0.

  ABSTRACT: Enzyme linked Immunosorbent Assay (ELISA) was done for the detection of antibodies to Cysticercus cellulosae in 135 cerebrospinal fluid (CSF) and 152 serum samples from patients suspected clinically of neurocysticercosis (NC), neurological disorders other than NC and controls by the use of crude cyst extract antigen. This assay was compared with the standard technique of indirect haemagglutination test (IHA). The results of the two techniques were matched with retrospective analysis of proven diagnosis of these patients. ELISA and IHA was found to be positive respectively in 88 and 84 percent of CSF and 92 and 87.2 percent of serum samples from proven NC patients. The IHA technique was found to be absolutely specific for the detection of antibodies in CSF samples while cross reactions were observed with ELISA technique in CSF from 5 patients, one each suffering from disappearing CT scan lesion, tubercular meningitis (culture negative), chronic meningitis, benign intracranial hypertension and non compressive myelopathy. However possibility of neurocysticercosis cannot be absolutely ruled out in such patients. Both the techniques were found to be highly non specific for the detection of antibodies in serum samples. The study suggests that either of the two techniques may be used for the detection of antibodies in CSF samples from clinically suspected NC patients with high degree of sensitivity and specificity.
