A case of a cestode parasite (Choanotaenia infundibulum) egg wasfound in the intestine of chicken which was sent to the Veterinary Research Institute, Ipoh in February 2014 for post-mortem. Other parasites found in the intestine were adult tapeworm and oocyst ofcoccidia. The examination of the chicken intestine for helminth ova was undertaken using direct examination of a simple wet smear of the intestinal content which was observed under compound microscope.The cestode parasite was identified based on helminthological keys by Soulsby, 1982.

Blastocystis is considered to be a zoonoses and it is believed that animals such as chicken constitute large reservoirs for human infection via the faecal-oral route. Therefore, Blastocystis infection was surveyed in free-range chicken and cage reared chicken comprising broiler birds for consumption as well as jungle fowls andsilkie chicken kept for recreation. Fresh faecal samples collected were examined by wet smear preparation and were cultured in Jones medium supplemented with 10% horse serum. Out of 107 chickens, it was found that most of the free-range chicken was positive for Blastocystis sp. with a high prevalence rate of 80%–100% in village chicken, jungle fowl and white silkie chicken. However, the cage-reared chicken, consisting of broiler chicken had no infection. The vacuolar form was the most common Blastocystis cell form found in cultures, similar to B. hominis.These cells were usually spherical and vary greatly in size, ranging from 10 μm to 30 μm in diameter. Owing to the free ranging and scavenging habits, the likelihood of acquiring the infection fromthe environment contaminated with the faecal material of animals with Blastocystis is high in free-range chicken as compared to caged chicken.

A total of five species of the nematodes, Acuaria spiralis, Gonyglonema ingluvicola, Ascaridia galli, Heterakis gallinarum and Oxyspirura mansoni were recovered from the Malaysia domestic chicken, Gallus domesticus and studied for their morphology. Scanning electron microscopy was used to study and observe the outer surface of the nematodes. The morphological of the five species ofnematodes were described and compared.
