Última Comparação da seqüência de nucleotídeos do gene da proteína capsidial de estirpes severas e premunizantes do Papaya ringspot virus Trop. Plant Pathol. Della Vecchia,Marilia G. S.; Camargo,Luis E. A.; Rezende,Jorge A. M.. This study compared three mild and three severe strains of Papaya ringspot virus - type W (PRSV-W), based on nucleotide and amino acid sequences of the capsid protein (CP) gene. The CP nucleotide sequences of the mild strains shared 98% to 100% identity. When compared to the severe strains the identity ranged from 93% to 95%, except in the case of PRSV-W-2R, which resulted from reversion of the mild strains PRSV-W-2. The CP sequence of the reverting strain showed 100% identity with the sequence of its parental strain. An insertion of six nucleotides in the core region of the CP gene, which reflected the addition of two amino acids (Asn and Asp) in the deduced sequence of the protein, was found in all mild strains. These sequence comparisons were used to... Tipo: Info:eu-repo/semantics/article Palavras-chave: Cross protection; Cucurbits; Molecular virology. Ano: 2003 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0100-41582003000600015 Molecular characterization of swine hepatitis E virus from Southeastern Brazil BJM Paiva,Helder Henrique; Tzaneva,Valentina; Haddad,Rodrigo; Yokosawa,Jonny. Despite serological evidences of presence of hepatitis E virus (HEV) in humans or other animals, until this study the virus had not been detected and molecular characterization of the isolate that circulates in Brazil had not been described. Thus, we collected stool samples of young pigs and tested for presence of HEV RNA by RT-PCR, using primers for partial amplification of ORF2 sequence. Phylogenetic analysis with sequence obtained from the amplified products revealed that the HEV isolate identified here was most closely related to HEV isolates of genotype 3, which is commonly detected in HEV infected pigs. Nucleotide sequence analyses carried out with the entire amplified fragment, ORF2/ORF3 overlapping and ORF2 non-overlapping sequences showed highest...
