Polymerase chain reaction mediated identification of Streptococcus uberis and Streptococcus parauberis using species-specific sequences of the genes encoding superoxide dismutase A and chaperonin 60*



Polymerase chain reaction mediated identification of Streptococcus uberis and Streptococcus parauberis using species-specific sequences of the genes encoding superoxide dismutase A and chaperonin 60*



Journal of Veterinary Medicine. B, Infectious Diseases and Veterinary Public Health 51(4): 180-184



Streptococcus uberis, a well-known bacterial pathogen associated with bovine mastitis, appears to be biochemically and serologically almost indistinguishable from the closely related species Streptococcus parauberis. In the present study, species-specific oligonucleotide primers were designed using internal parts of the genes sodA, encoding superoxide dismutase A, and cpn60 encoding chaperonin 60 of S. uberis and S. parauberis, respectively. The two oligonucleotide primer pairs allowed a rapid and reliable PCR-mediated identification and differentiation of both species. These studies, performed with S. uberis and S. parauberis reference cultures and clinical isolates from routine diagnostics, revealed that the occurrence of S. parauberis as causative agent of bovine mastitis appears to be rare. In addition the sodA and cpn60 sequence data confirmed that both species could taxonomically be classified to the pyogenic group of genus Streptococcus.
