Abstract
The study was conducted on 65 local adult chickens (Gallus domesticus) to investigate macro - and microscopically presence of external and internal parasites and their prevalence in Sulaimani region-Kurdistan/Iraq from May to July 2012. Results showed that 90.77 % out of total examined chickens were infested with ecto-parasites, out of that 81.36 % (48/59) were infested with lice such as (Menacanthus stramineus, Goniocotes gallinae, Menopon gallinae, Goniodes gigas, Cuclotogaster heterographus ) and 62.72 (37/59) of it with larval stage of soft tick such as (Argas persicus). Mixed infestations with more than two ecto-parasite species were detected. On the other hand 89.23% out of 65 examined chickens were infected by internal parasites including nematodes and cestodes such as (Heterakis gallinarum which formed 81% and the remains were Ascaridia galli, Cheilospirura hamulosa, Capillaria spp., Raillietina spp., Choanotaenia infundibulum, Amoebotaenia sphenoides, Hymenolepis carioca and Davaniea proglottina).
Highlights
Similar to our finding (10) reported that 100% of the chickens, comprising both local and exotic breeds, from free-range production system harbored ecto-parasites in Nigeria, of the total 90.77 %, 81.36 % (48/59) were infested with different species of lice and 62.72 % (37/59) were infested with larval stage of soft tick Argas persicus (Table 2)
They spend their entire lives on chickens and can be found on the skin around the vent and on the breast and thighs, they feed on skin and feathers(5), but sometimes may consume blood (8).Such birds could be seen pecking themselves and rolling on lose soil or ashes for relief were lice continuously on the birds (13)
Our result showed that 62.72% of examined chickens were infested with the larval stage of soft tick Argas persicus, (Fig. 2), (13) reported in Zimbabwe that tick infestation were 30%
