Torque Teno Virus (TTV) is Prevalent in Brazilian Non-human Primates and Chickens (Gallus gallus domesticus) International Journal of Morphology
Catroxo,M. H. B; Nishiya,A; Sabino,E; Teixeira,P. S; Petrella,S; Milanelo,L; Vieira,J.C.F; Diaz,R. S.
Torque Teno virus (TTV) is an infectious agent of worldwide distribution isolated by the first time as the agent of an acute post-transfusion hepatitis in a patient in Japan. It has been classified into a new floating genus called Anellovirus. Recent studies showed that TTV can also be identified in serum specimens obtained from domesticated farm animals and from non-human primates. To better understand the relationship between TTV and their hosts, a study to detect virus in the serum and whole blood of Brazilian non-human primates and in the plasm of chickens was performed by applying the PCR-UTR-A technique, followed by a genomic sequence and phylogenetic analysis. By nested-PCR-UTR, the DNA of TTV was detected in sera from 4 (5.3%) of 75 Cebus apella, 2...

Minimum free energy predicted base pairing in the 39 nt spliced leader and 5’ UTR of calmodulin mRNA from Trypanosoma cruzi: influence of the multiple trans-splicing sites Anais da ABC (AABC)
SAMUDIO,FRANKLYN; BRANDÃO,ADEILTON.
ABSTRACT We analyzed the compositional changes and the stable base pairs in the predicted secondary structure of the 5’ UTR calmodulin mRNA in T. cruzi. The three copies of calmodulin in T. cruzi genome display variable position of the trans splicing sites and give rise to several mRNA that differs slightly on 5’ UTR composition in the epimastigote stage. We show that the pattern of high probability base pairs in the minimum free energy predicted secondary structures of the calmodulin 5’ UTR remains unchanged despite the nucleotide composition variation. However, the 39 nt spliced leader (mini-exon, the 5’ exon sequence transferred to trypanosome mRNAs by the mechanism of trans splicing) shows a variable pattern of high and low probability base pairing as...
