Diversidade genotípica de rotavírus suínos no Estado de São Paulo

Abstract: Rotavírus é uma das causas mais comuns de diarréia tanto em humanos quanto em diferentes espécies animais. Foi conduzido um estudo transversal a partir de 144 amostras fecais diarréicas colhidas de leitões, provenientes de 16 criações comerciais distribuídas por 10 municípios do Estado de São Paulo, Brasil, com o objetivo de se detectar a ocorrência de rotavírus e realizar sua caracterização molecular quanto seus genotipos G e P. Um total de 43 amostras (29,86%) foram positivas para rotavírus por Eletroforese … Show more

“…This ϐinding can be considered of major epidemiological signiϐicance in view of the scanty reports of this genotype in Brazilian cattle, and may be a result of sharinf of the same environment by cattle and pigs. On the other hand, Gregori et al 2009 also observed the presence of predominantly bovine genotypes for the molecular characterization of fecal samples from pigs in São Paulo state, suggesting a potential cross--infection of the virus.…”

“…Our rate in diarrheic piglets is higher than the 7.5% rate reported by Lippke et al (2011) and similar to the 13% rate reported by Yaeger (2007). In contrast, Gregori et al (2009) reported a rotavirus frequency of 29.9% (as determined by PAGE) in stool samples from 144 piglets with clinical diarrhea; unfortunately, the authors did not report the age of the sampled animals. According to Roehe et al (1989), piglets are most commonly infected by rotavirus between 15 and 30 days of age.…”

“…The G3 and G5 genotypes of porcine group A rotaviruses have been reported in different countries, including the United States, Canada, Japan, Thailand, and Brazil (13)(14)(15)(16)(17). However, the G9 genotype presented the highest degree of amino acid identity with a human strain (96.6% to the sequence with accession number AF060487).…”
