The presence of Citrus tristeza virus (CTV) in Turkey has been known since the 1960s and the virus was detected in all citrus growing regions of the country. Even though serological and biological characteristics of CTV have been studied since the 1980s, molecular characteristics of CTV isolates have not been studied to date in Turkey. In this study, molecular characteristics of 15 CTV isolates collected from different citrus growing regions of Turkey were determined by amplification, cloning, and sequencing of their major coat protein (CP) genes. The sequence analysis showed that the CP genes were highly conserved among Turkish isolates. However, isolates from different regions showed more genetic variation than isolates from the same region. Turkish isolates were clustered into three phylogenetic groups showing no association with geographical origins, host, or symptoms induced in indicator plants. Phylogenetic analysis of Turkish isolates with isolates from different citrus growing regions of the world including well-characterized type isolates of previously established strain specific groups revealed that some Turkish isolates were closely related to severe quick decline or stem pitting isolates. The results demonstrated that although CTV isolates from Turkey are considered biologically mild, majority of them contain severe components potentially causing quick decline or stem pitting.

Spring viremia of carp (SVC) is a disease caused by a virus belonging to the genus Vesiculovirus, family Rhabdoviridae. The SVC virus is divided into four genogroups, Ia, Ib, Ic, and Id, due to its geographical distribution. This study aimed to identify the genotype of the SVC virus circulating in Poland. Polish SVC virus isolates were propagated on EPC and FHM cell lines, and genetic material (RNA) was isolated. The virus was detected in test samples by reverse transcription, sequenced and analyzed using MEGA 6.06 software. The phylogenetic tree was constructed by the Neighbor-Joining method. The results of phylogenetic analysis revealed the presence of two genogroups of the SVC virus in Poland. Most of Polish isolates belonged to the genogroup Id, as do isolates AY196200 from the Czech Republic, Z37505 from Belgium and EF593149 from the United States. Only two Polish isolates from Silesian Voivodeship were more closely related to Chinese and US isolates belonging to the genogroup Ia. There were no isolates belonging to the genogroups Ib and Ic. Nucleotide sequence analysis revealed certain point mutations between particular isolates. Knowledge on the genetic variants of the SVC virus circulating in Poland will be useful in epizootic investigations and preventive measures to protect Polish aquaculture from new variants from the neighboring countries
