Kırıkkale Yöresinde Bulunan Küçük Ruminantlarda Mavidil, Maedi-Visna ve Caprine Arthritis-Encephalitis Enfeksiyonlarının Serolojik ve Epidemiyolojik Araştırılması
Viral infections cause important problems and significant economic loses in sheep and goats that can be protected by an investigation of infections. This study aimed to determine the sheep and goat viral infections including bluetongue virus (BTV), maedivisna virus (MVV) and caprine arthritis-encephalitis virus (CAEV) in Kirikkale city located in Central Anatolia region of Turkey. Blood samples...
متن کاملDemonstration of coinfection with and recombination by caprine arthritis-encephalitis virus and maedi-visna virus in naturally infected goats.
Recombination of different strains and subtypes is a hallmark of lentivirus infections, particularly for human immunodeficiency virus, and contributes significantly to viral diversity and evolution both within individual hosts and within populations. Recombinant viruses are generated in individuals coinfected or superinfected with more than one lentiviral strain or subtype. This, however, has n...
متن کاملMaedi-visna virus and caprine arthritis encephalitis virus genomes encode a Vpr-like but no Tat protein.
A small open reading frame (ORF) in maedi-visna virus (MVV) and caprine arthritis encephalitis virus (CAEV) was initially named "tat" by analogy with a similarly placed ORF in the primate lentiviruses. The encoded "Tat" protein was ascribed the function of up regulation of the viral transcription from the long terminal repeat (LTR) promoter, but we have recently reported that MVV and CAEV Tat p...
متن کاملKoyun ve Sığırlardan İzole Edilen Arcanobacterium pyogenes Suşlarının Moleküler Karakterizasyonu
The purpose of this study was to determine the presence of virulence genes, perform typing for the characterization of Arcanobacterium pyogenes field strains, and investigate the correlation between clonal types, virulence genes and occurence of disease. The isolates (n=51) used in this study were isolated from different sources (liver (n=4) of sheep; liver (n=25), lungs (n=5), broncho-alveolar...
متن کاملConserved sequence motifs involving the tat reading frame of Brazilian caprine lentiviruses indicate affiliations to both caprine arthritis-encephalitis virus and visna-maedi virus.
The sequence variation in small ruminant lentiviruses from Brazilian herds of milking goats was sampled in a representative region of the pol gene and in a region including the entire tat open reading frame. Clones were amplified from cDNA derived from virus produced in vitro using primers targetting conserved sequences of the pol gene. Iterative sequencing of clones indicated that animals from...
