Mycoplasma gallisepticum ve Mycoplasma synoviae için Tanısal Kantitatif Gerçek Zamanlı PCR Geliştirilmesi

Abstract

Avian mycoplasmas are associated with respiratory disease, synovitis, poor quality of day-old chicks and poor performance. The main approach used for the diagnosis of avian mycoplasmas is isolation and identification of the microorganism. Since the bacteria are slow growing fastidious organisms, conventional methods are time consuming, laborious and require experienced personnel. For this reason, we aimed to develop a rapid detection method for Mycoplasma gallisepticum and Mycoplasma synoviae by quantitative real-time polymerase chain reaction (qPCR). For this purpose, the lipoprotein (lp) and variable lipoprotein hemagglutinin (vlhA) genes were used to detect M. gallisepticum and M. synoviae, respectively. The limit of detection (LOD) of the assay was determined to be 100- 101 DNA/µl from artificially contaminated swab samples. The specificity and sensitivity ratios were 100%. Overall, these results indicate that this qPCR method can be accurately used for detection of MG and MS.
