Seroprevalence of Brucellosis in Livestock in Khuzestan Province, Southwest of Iran, 2008-2012

Öz

ABSTRACT

Brucellosis is a zoonotic problem worldwide, especially in developing countries and specifically in Iran, where it is endemic. This study aimed to investigate the seroprevalence of brucellosis among livestock in the 18 districts of Khuzestan Province in Southwest Iran. Serum samples of 87798 cattle and 119020 sheep were tested using the Rose Bengal Plate Test, and positive results were confirmed with serum agglutination tests (SAT) and 2-mercaptoethanol SAT (2ME-SAT). The seroprevalence derived from total samples was 0.72% for cattle and 3.01% for sheep, revealing that though brucellosis is present among livestock populations in Khuzestan and that infection among sheep is significantly higher than among cattle (P<0.05), seroprevalence in general was much lower than indicated by results of other studies of livestock in the Middle East and neighboring regions. These results nevertheless recommend implementing a policy of transparency regarding brucellosis as well as measures to effectively eradicate the disease.

ÖZET 

2008-2012 YILLARI ARASINDA GÜNEYBATI İRAN KHUZESTAN İLİNDE YETİŞTİRİLEN
ÇİFTLİK HAYVANLARINDA BRUSELLOZUN SEROPREVALANSI

Bruselloz endemik seyrettiği İran ve gelişen ülkeler başta olmak üzere, dünya çapında yaygın görülen bir zoonotik hastalıktır. Çalışmada Güneybatı İran’da yer alan Khuzestan ilinin 18 farklı semtinde ki çiftlik hayvanları arasında brusellozun seroprevalansının araştırılması amaçlandı. 87798 sığır ve 119020 koyun serum örneği Rose Bengal Lam Aglütinasyon tekniği ile test edildi, pozitif örnekler serum aglütinasyon testi (SAT) ve 2-merkaptoetanol SAT (2ME-SAT) ile doğrulandı. Örneklerden elde edilen seroprevalans oranları, sığırlar için %0,72, koyunlarda ise %3,01 olup Khuzestan’da ki çiftlik hayvanlarında brusellozun varlığını ve sığırlara göre koyunlarda enfeksiyonun istatistiksel olarak daha yüksek oranda (P<0,05) seyrettiğini ortaya çıkardı. Bununla birlikte belirlenen genel seroprevalansın komşu bölgelerdeki ve Orta Doğu’daki çiftlik hayvanları üzerinde yapılan diğer çalışmalardaki sonuçlara göre çok daha düşük olduğu saptandı. Bu sonuçlar yine de bruselloz ile ilgili olarak şeffaflık politikası ile birlikte etkili eradikasyon tedbirlerinin uygulanması gerektiğini göstermektedir.
