An immunosuppressive factor(s) which is heat stable, and dialysable, with a molecular weight less than 10,000 molecular weight, and is not species specific, has been shown to be produced during the in vitro culture of Onchocerca gibsoni microfilariae. The factor(s) is capable of abolishing lymphocyte mitogenesis induced by Con A in bovine lymphocytes and(More)
To compare methods for diagnosing Bancroftian filariasis, six hundred and seventy four people from rural areas of Papua New Guinea were screened using microfilaraemia, the Og4C3 antigen capture ELISA, an ELISA to detect IgG4 specific antibodies and clinical examination. Both ELISA tests detected around twice the number of positive cases than those detected(More)
Numerous abattoir studies have been undertaken in countries in Africa and the Middle East as a relatively inexpensive means of collecting regional information on prevalence and burden of Fasciola gigantica in cattle, and the extent of loss from condemnation of liver and carcases that are jaundiced or emaciated as a consequence of infection (Spithill et al.,(More)
Farmer's cattle were treated with triclabendazole and used as tracer animals to detect new infections with Fasciola gigantica in three villages located on the bank of the Bassac River (a major tributary of the Mekong River) and in a fourth village located on farmland away from the river, from April 1999 until January 2001. The month of infection was(More)
Progressive weight gain, faecal egg counts, packed cell volume, percent eosinophils in blood, serum antibody and serum levels of glutamate dehydrogenase and gamma-glutamyl transpeptidase were recorded in seven swamp buffalo (Bubalis bubalis), 7 Ongole (Bos indicus) and four Bali calves (Bos sundiacus) which were infected orally with 15 metacercariae of(More)
