Aprimoramento da PCR para Mycoplasma gallisepticum pelo encurtamento do "amplicon" e ajustes no processamento da amostra

Abstract: A micoplasmose por Mycoplasma gallisepticum (MG) causa enormes prejuízos aos avicultores e, apesar disto, ainda carece de aprimoramento diagnóstico. O diagnóstico molecular, principalmente PCR, tem sido aprimorado pela facilidade em detectar o agente de forma direta e ser um método rápido e eficaz. Neste estudo, desenvolveu-se uma PCR para MG com "amplicon" de 481 pares de base (pb), denominado MG-PCR/481, no qual se utilizou um método simples de processamento das amostras, constituídas de cultivos de diferent… Show more

“…For molecular detection, a 0.5mL aliquot of the collected sample was submitted to DNA extraction by the phenol-chloroform adapted method (Sambrook & Russell, 2006). DNA amount and quality determination was performed in BiodropTouch ® (Biochrom, Harvard Bioscience, EUA) with subsequent PCR for the detection of Mollicutes class, MG, and MS according to Uphoff & Drexler (2002), Nascimento et al (2005a) and Lauerman et al (1993) respectively. The PCR for detection of Mollicutes was performed containing 1X PCR buffer (10mM Tris-HCl, pH 8.0 and 50mM of KCl), 2.0 mM of MgCl 2 , 0.8 mM of dNTP, 1U of Taq Polymerase (Ludwig, Brazil), 0.6 µM of each primer (Invitrogen, Brazil) and 5µL of DNA.…”
