The helminth worms group involving nematodes (roundworms), cestodes (tapeworms) and trematodes (flatworms) which are widely reported with mixed infection also common (Permin et al., 1997; Poulsen, 2000). Nematodes or roundworms are the most important group of helminth parasites of poultry, worms are elongated, cylindrical and unsegmented, and most roundworms affect the gastrointestinal tract (GI tract), with an occasional parasite affecting the trachea or eye. Round worms are directely life cycle, and it is particularly short 21 days. The most prevalent helminth species in chicken are Ascaridia galli, Capillaria spp and Heterakis gallinarum (Permin and Hansen, 1998; Permin et al., 1999 and Kaufmann et al., 2011a). Ascarids or the large roundworms A. galli the adult worm which can easily seen by naked eye, it is a one of the most common damaging parasitic that effect chickens (Gauly et al., 2001). The worms invade the upper small intestine of…show more content…
Each species of tapeworm attaches to a different section of the digestive tract, moreover grow by forming new segments (called proglottids) just behind their head (scolex), and each segment contains both male and female sexual organs. The worms shed segments on the tail end mature in groups of two to three on a daily basis, passing out of the intestine contains hundreds of eggs with the droppings which are actually first stage larvae. Tapeworms have an indirect lifecycle require an intermediate host to complete their life cycle. These intermediate hosts include ants, beetles, houseflies, slugs, snails, earthworms, and termites. For free-range birds, snails and earthworms can serve as intermediate hosts. The chickens infected with cestodes presented general symptoms loss of appetite, slow growth, enteritis, diarrhea and hemorrhages (Gordon and Jordon,
