Abstract: Small ruminant lentiviruses (SRLV) are widely distributed in the world and cause productive and economic losses. These pathogens have high genetic variability, which hinders diagnosis by molecular methods. Molecular characterization studies are good strategies for elaborating programs aimed to control or eradicate diseases. Hence, this study aimed to sequence, characterize and compare strains of SRLV, which were isolated from naturally infected goats from the states of Ceará, Rio Grande do Norte and Minas Gerais, Brazil, based on total nucleotide sequences of gag and pol genes. SRLV isolates from the microbiological collection of Sheep and Goat of Embrapa were cultured in goat synovial membrane. Supernatants containing cells were stored and viral particles were purified with sucrose density gradient centrifugation for RNA extraction. Then, sequencing in HiSeq 2500 platform (Illumina) was performed to obtain the total genome of the SRLV strains. The software MEGA version 7.0 was used for sequence editing and phylogeny analysis. A total of 17 isolates were multiplied in cellular culture and six were viable, which were two from Minas Gerais (MG), one from Rio Grande do Norte (RN) and three from Ceará (CE). Two sequences were obtained from the sequencing by synthesis, one from MG (BRMG CNPC) and one from RN (BRRN CNPC). From the total SRLV genome (9,200 bases), sample BRMG CNPC generated a consensus of 6,378 bases, approximately 69,34% of the viral genome and sample BRRN CNPC generated a consensus of 5,351 bases, which comprised 58.16% of the total genome. Samples in this study demonstrated closer phylogenetic relation with genotype B (B1 group). The remaining strains sequenced in Brazil are also present in the same group with the exception of three samples from genotype A. Immunodominant regions of gag gene and motifs of pol gene were similar to the standard CAEV Cork strain. For the first time, the complete gag and pol genes were sequenced in Brazil from the strain BRMG CNPC isolated in Minas Gerais state. In addition, 2490 bases from the total of 3316 bases were sequenced from the pol gene of the BRRN CNPC sample from Rio Grande do Norte.
