|Project description|| Helminths belong to two major groups: platyhelminthes and nemathelminthes (Ijagboneand Olagunju, 2006). Nemathelminthes include roundworms, hook worms and whip worms which cause high morbidity and mortality in humans and animals. These parasites are common in sub-Saharan Africa due to multiple factors which include poor hygienic conditions, poverty, malnutrition, ignorance, lack of clean water as well as limited access to preventive measures and health care(Zvi et al., 2010).
Gastrointestinal parasites have also been reported to be a major menace facing animals and birds. These parasites are known todiminish the animals’ survival, growth rate and reproductive performance thus affecting their overall production. A study conducted in Kenya, showed that Helminthiosis accounted for the second most important disease accounting for 21% of the deaths from parasitic conditions, between 1989 and 1998 in chicken (Permin et al., 1999).It has been estimated that more than 750 million chickens, guinea fowls and ducklings in Africa die each year as a result of various infections, helminthosis being a major contributor (Maturet al., 2010).
Therefore, the economic and social impact of helminth cannot be underestimated with the effect in human and livestock ranging from stunted growth, reduced weight gain, diarrhoea,anaemia, respiratory problems, reduced productivity and death especially in the tropics and developing countries(Jozef et al., 2011;Velkers et al.,2011).
The use of synthetic drugs has been effective in treatment and control of helminth infections However, development of anti-helmintic resistance, the presence ofdrug residues, deficient livestock extension services and the high cost of conventional anti-helmintics, has led to the evaluation of medicinal plants as an alternative source of anti-helmintics for treatment of human and livestock diseases.
