Gastrointestinal Helminthic Infections of Local Chickens, Kept under the Traditional System in the Isfahan Region, Center of Iran

Yerli tavuk ırkları İran ekonomisinde özellikle kırsal bölgelerde önemli bir rol oynamaktadır. İran'daki yerli kuşların sağlık durumları; daha özel olarakta parazitik enfeksiyonel hastalıklarla beraber ekonomik faktörlere karşı bu çalışma İran'ın merkezinde yer alan İsfahan'daki yerel tavukların sindirim kanalındaki helmint türlerinin varlığının ve şiddetinin belirlenmesi için yapılmıştır. Bu amaçla 2010-2011 yılları arasında Isfahan'ın 5 farklı bölgesinden rastgele 100 adet yerel tavuk toplanmıştır. Tavuklar mezbahada kesildikten sonra alimenter kanal ve gastrointestinal kanallarları helmintler açısından değerlendirildi. Çalışmada üç adet nematode, 2 tane sestod türü tespit edildi. Trematod türüne ise rastlanmadı. İncelen 100 yerel tavuktan, 81'i enfekteydi (%81). Türlerin dağılımı Raillietina tetragona (%46), Heterakis gallinarum (%42), Ascaridia galli (%36), Raillietina echinibothrida (%7) and Subulura brumpti (%2) gibidir. Bölgedeki bütün parazitlerin tanınabilmesi için ve enfeksiyon, hastalık ve ölüm nedenlerinin daha iyi anlaşılabilmesi için daha fazla çalışma yapılması gerekmektedir. Bu çalışmalar bölgedeki yerel tavukların mortalite oranlarının düşürülmesi de dahil olarak olanakların düzeltilmesinde yapıtaşı olacaktır. Bu nedenle periyodik olarak yapılan antihelmentik tedaviler ile birlikte periyodik olarak paraziter incelemelerin de yapılması gerekmektir.

İRANIN MERKEZİNDE BULUNAN ISFAHAN BÖLGESİNDE GELENEKSEL SİSTEMLE BAKILAN YEREL TAVUKLARDAKİ GASTROİNTESTİNAL HELMİNTİK ENFEKSİYONLAR

Indigenous chickens play an essential role in the Iranian economy especially in the rural sector. Juxtaposing the economic factor against the state of the health of the indigenous birds in Iran, more specifically the prevalence of parasitic infectious diseases, this study was conducted to determine the presence and intensity of species of helminthes in the alimentary canals of the local chickens in the Isfahan area, which is centrally located in Iran. For the purpose of this study, 100 local chickens from five different parts of the geographic region of Isfahan were collected randomly, during 2010-2011. The chickens were slaughtered and their gastrointestinal tracts and alimentary canals where examined for the presence of helminthes. The study identified three nematodes, and two cestodes species. No trematodes were found. From the 100 local chickens examined, 81 were infected (81%). The distribution of the presence of species was as follows: Raillietina tetragona (46%), Heterakis gallinarum (42%), Ascaridia galli (36%), Raillietina echinibothrida (7%) and Subulura brumpti (2%). More research is needed to identify all parasites in the region, and to understand the causes of infection, disease and death. Such research will provide the basis for improving the conditions including a reduction of the high mortality rate of local chickens in the area. It is therefore necessary that periodical parasitological investigations as well as anthelmintic treatments should be carried out regularly.
