Ocorrência de anticorpos contra o vírus Maedi-Visna em ovinos Santa Inês, no Estado de Sergipe, Brasil

Abstract: Small Ruminant Lentiviruses (SRLV) are infectious diseases of viral etiology caused by retroviruses, characterized for being a slowly progressive degenerative disease. The aim of this study was to determine the occurrence of antibodies against lentivirus in the flock of Santa Inês sheep in Sergipe, Brazil. A minimum number of samples was analyzed by the Astudillo calculation, with an expected prevalence (p) of 10%, error rate (α) of 20% and confidence level of 95% (g = 1.96) obtaining the minimum number of sam… Show more

“…We detected 6.53% seropositive sheep, slightly higher than data from in other sheep serological studies in Northeast Brazil. For example, 0.11% and 0.34% of tested sheep were seropositive studies from Sergipe (MENDONÇA et al, 2013) and Bahia (MARTINEZ et al, 2009), respectively. Data from Pernambuco revealed 5.2%, 1.07% and 0.26% seropositivity (OLIVEIRA et al, 2006;COSTA et al, 2007;MELO et al, 2016).…”

“…7% and 4.6%, respectively (PINHEIRO et al, 2012). Previous serologic studies reported that both diseases are widespread throughout the northeast, ranging from 0.29% prevalence in Bahia (LIMA et al, 2013) to 11.0% in Rio Grande do Norte (SILVA et al, 2005) for CAEV, and from 0.11% in Sergipe (MENDONÇA et al, 2013) to 31.67% in Ceará (ALMEIDA et al, 2003) for MVV. These results reinforce the need for seroepidemiological studies in the region that elucidate the transmission mechanisms of lentiviral diseases.…”

“…Resultados demonstrando baixas prevalências foram constatados em outros estados nordestinos: 1,0% em Pernambuco , 0,5 e 0,3% na Bahia (SOUZA et al, 2007;MARTINEZ et al, 2010) e 0,1% em Sergipe (MENDONÇA et al, 2013). No Tocantins foi encontrado o resultado de 0,9% (SOBRINHO et al, 2008).…”

“…No Brasil, o primeiro registro de ovinos soropositivos ocorreu no Rio Grande do Sul (Dal Pizzol et al, 1989). Em seguida, vários estudos soroepidemiológicos foram realizados em ovinos, por meio do IDGA, em diversos estados do Nordeste como Bahia (Souza et al, 2007;Barros et al, 2010;Martinez et al, 2011), Ceará (Almeida et al, 2003;Araújo et al, 2004b;Alves et al, 2011), Pernambuco (Oliveira et al, 2006;Landim et al, 2011), Piauí (Batista et al, 2004Sampaio Júnior, 2007;Sousa et al, 2011), Sergipe (Melo et al, 2003;Mendonça et al, 2013;Rizzo et al, 2015) e Tocantins (Sobrinho et al, 2008). Considerando a relevância da ovinocultura para o Maranhão aliada a inexistência de dados epidemiológicos sobre a MV no estado, o presente estudo foi conduzido com o objetivo de determinar a soroprevalência do MVV em rebanhos das três principais mesorregiões produtoras de ovinos do Maranhão.…”
