Resumo

The virome composition of blood units deferred due to symptomatic disease of the donors reported after blood donation may reveal novel or unsuspected viral agents which may have impact in the area of hemotherapy. The objective of this study was to compare the virome of blood donations obtained from two distantly located blood collecting institutions in the Saqo Paulo State and deferred from use due to post donation illness reports (PDIR). Plasma samples with PDIR due to different symptoms were collected in two cities of the Sao Paulo State (Sao Paulo city, 28 samples and Ribeirao Preto city, 11 samples). The samples were assembled in pools and sequenced in Illumina NextSeq 550 sequencer. The obtained raw sequencing data was analyzed using bioinformatic pipeline aiming viral identification. Phylogenetic classification of the most important contigs was also performed. The virome composition of the plasma samples obtained in both cities was different. This was more pronounced for some specific anellovirus types and the human pegivirus-1 (HPgV-1) which were exclusively found among donations obtained from the city of Sao Paulo. On the other hand, in PDIR samples from Ribeirao Preto, Dengue -2 reads were more abundant compared to commensal viral representatives. The obtained virome findings show that the differential viral abundance is related to geographic localization and specific disease endemicity. The virome of PDIR samples may be used to more profoundly analyze the hypothetic transfusion threats in a given location. (AU)
