Abstract:
Mycoplasmas are important avian pathogens, which can cause both respiratory disease and synovitis in poultry that result in considerable economic losses to the poultry industry all over the world. The aim of this study was to determine the prevalence of Mycoplasma gallisepticum and Mycoplasma synoviae infections among commercial poultry flocks in Khouzestan province, Iran, using the polymerase chain reaction (PCR) technique. Totally, ۲۹۰ tracheal swab samples were collected from ۱۹ broiler flocks and ۴ layer-breeder flocks, with or without respiratory signs, in different areas of Khouzestan province within six months. The PCR tests were applied for the specific amplification of ۱۶S rRNA (۱۸۵ bp) and vlhA (۳۹۲ bp) genes. Out of ۱۰۰ swab samples obtained from the layer-breeder flocks, ۱ and ۷۲ specimens were positive for M. gallisepticum and M. synoviae, respectively. In this regard, out of the ۴ layer-breeder flocks, ۱ (۲۵%) and ۴ (۱۰۰%) flocks were positive for M. gallisepticum and M. synoviae, respectively. However, none of the studied broiler flocks were M. gallisepticum- or M. synoviae-positive. According to the results, the PCR technique could be concluded as a rapid method for the accurate identification of M. gallisepticum and M. synoviae infections in commercial poultry flocks. The results were indicative of the low prevalence of M. gallisepticum in the studied flocks in Khouzestan province. On the other hand, M. synoviae was widely distributed among layer-breeder flocks in this province.
