Abstract: Mycoplasma iowae is primarily a pathogen of turkeys and, although uncommon, it still persists in some areas of the world, where it may cause embryo mortality and leg lesions. A species-specific diagnostic polymerase chain reaction was developed using a forward primer based in the intergenic spacer region between the 16S rRNA and the 23S rRNA ribosomal genes and a reverse primer located within the 23S rRNA gene. The polymerase chain reaction proved to be both sensitive and specific. It detected M. iowae DNA in the six reference strains of serotypes I, J, K, N, Q and R and in 28 field isolates. With the six serotypes the test detected between 1 and 5 pg of M. iowae DNA. There were no non-specific reactions with the other avian Mycoplasma species. When the closest phylogenetically related species were checked, a weak reaction with Mycoplasma muris was observed that disappeared when the annealing temperature was increased by 2 degrees C.
