title: Prevalence and molecular characterization of bovine coenurosis from Eastern Anatolian region of Turkey.
abstract: This study was conducted to determine the prevalence and molecular characteristics of Coenurus cerebralis, the metacestode of Taenia multiceps in cattle from Erzurum province located in eastern region of Turkey between November 2009 and April 2010. Five of 1045 brains of cattle (0.47%) were found to be infected with Coenurus cysts. The characteristics and morphology of C. cerebralis were seen in all the cysts. The cyts from three infected cattle were genetically analyzed and confirmed to be T. multiceps metacestodes by NAD1 and COX1 mitochondrial gene sequence analysis. Pairwise comparison between the NAD1 sequences of the T. multiceps isolates from Erzurum and other T. multiceps isolates available in GenBank showed differences ranging from 0.6 to 2.9%, while COX1 sequences showed differences ranging from 0.2 to 2.6%. Considering the two genes, it was seen that all of the three isolates from Erzurum province were in the same group according to phylogenetic analyses. The present findings could provide a stimulus for future studies on the systematic relationships and epidemiology of lesser-known taeniid cestodes in the region, employing mitochondrial sequence data sets.
