ABSTRACT
In this study, 22 bacterial isolates from swine necropsy specimens, which were biochemically identified as Streptococcus suis and other Streptococcus species, were re-examined using species-specific PCR for authentic S. suis and 16S rRNA gene sequencing for the verification of the former judge. Identification of S. suis on the basis of biochemical characteristics showed high false-positive (70.6%) and false-negative (60%) rates. The authentic S. suis showed various capsular polysaccharide synthesis gene types, including type 2 that often isolated from human cases. Five of 22 isolates did not even belong to the genus Streptococcus. These results suggested that the misidentification of the causative pathogen in routine veterinary diagnosis could be a substantial obstacle for the control of emerging infectious diseases.
