Characterisation of Env and Gag Gene Fragments of Bovine Leukemia Viruses (Blvs) From Cattle in Turkey
(Springer Wien, 2011) Alkan, Feray; Oguzoglu, Tuba Cigdem; Timurkan, Mehmet Ozkan; Karapinar, Zeynep
The aim of this work was to investigate the molecular characteristics of bovine leukemia viruses (BLVs) in Turkey. The variability of env and gag fragments of BLVs was examined using DNA from blood samples obtained for sequence analysis of BLVs in four cattle herds from three different geographical areas in Turkey. The env gene sequences were highly similar to those of Brasilian, Argentine, and Japanese BLV strains, while gag genes from Turkish BLV isolates showed greatest similarity to those of Iranian isolates. This paper is the first report on the partial characterisation of env and gag genetic fragments of BLVs from Turkey.
First Genetic Characterization of Equine Adenovirus Type 1 (eadv-1) in Turkey
(Elsevier Sci Ltd, 2012) Ataseven, Veysel Soydal; Oguzoglu, Tuba Cigdem; Basaran-Karapinar, Zeynep; Bilge-Dagalp, Seval
Equine adenovirus type 1 (EAdV-1) is a cause of repiratory tract infection in equids. In present study for the first time in Turkey, the prevalence of EAdV-1 in nasal swab samples obtained from horses showing respiratory symptoms was investigated by polymerase chain reaction (PCR), and molecular characterization of the hexon gene detected in the Turkish (TR) strain was performed. Overall, the prevalence of EAdV-1 was found low (1.4%) as indicated by a positive PCR reaction from the nasal swab extracts tested. Phylogenetic analysis based on the partial sequences of the hexon gene of a TR-EAdV-1 strain with those of previously isolated AdVs from different mammals and an EAdV-1 M1 strain showed that the EAdV-1 strains were placed into a unique cluster. Although the TR-EAdV-1 strain was closely related to CAV-1, CAV-2 and bat adenovirus reference strains, larger-scale studies are necessary to better understand the molecular epidemiology and population structure of EAdV-1 in Turkey.
