    Abstract

    Genomic diversity among strains of Mycoplasma hyosynoviae isolated in Denmark was assessed by using amplified fragment length polymorphism (AFLP) analysis. Ninety-six strains, obtained from different specimens and geographical locations during 30 years and the type strain of M. hyosynoviae S16(T) were concurrently examined for variance in BglII-MfeI and EcoRI-Csp6I-A AFLP markers. A total of 56 different genomic fingerprints having an overall similarity between 77 and 96% were detected. No correlation between AFLP variability and period of isolation or anatomical site of isolation could be demonstrated. An examination of the clonal appearance of M. hyosynoviae isolates recovered from seven herds affected with arthritis revealed presence of several genotypically distinct variants of the organism in a single herd, indicating that different strains may simultaneously be involved in an outbreak of the disease.
