(Pesquisa Veterinária Brasileira, 2012-03-01) [Artigo]
Este estudo teve como objetivo avaliar o limiar de detecção da técnica de PCR multiplex fluorescente aliada a eletroforese capilar na detecção de agentes infecciosos em amostras de sêmen experimentalmente contaminadas com ...
Caracterização molecular de Cryptosporidium spp. em bezerros (Bos taurus e Bos indicus) no município de Formiga, Minas Gerais - Brasil
(Semina: Ciências Agrárias, 2013-01-01) [Artigo]
A criptosporidiose, é a enfermidade de veiculação hídrica, possui como agravante a dificuldade de prevenção da contaminação ambiental e ausência de medidas terapêuticas eficazes. Com acentuada importância na bovinocultura, ...
Detecção de Histophilus somni (Haemophilus somnus) no sêmen bovino mediante reação em cadeia pela polimerase (PCR)
(Revista Acadêmica: Ciências Agrárias e Ambientais, 2014) [Artigo]
The present study evaluated the use of PCR for Histophilus somni detection in bovine semen. Semen samples were experimentally infected with H. somni at dilutions ranging from 107 to 101 bacteria/mL and subjected to DNA ...
Assessment of autozygosity in Nellore cows (Bos indicus) through high-density SNP genotypes
(Frontiers In Genetics, 2015) [Artigo]
The use of relatively low numbers of sires in cattle breeding programs, particularly on those for carcass and weight traits in Nellore beef cattle (Bos indicus) in Brazil, has always raised concerns about inbreeding, which ...
