Phenotypic and genotypic characteristics of Streptococcus porcinus isolated from human sources.
The phenotypic and genotypic characteristics of 25 Streptococcus porcinus isolates recovered from human sources were investigated and compared to the characteristics of 17 reference strains obtained from nonhuman sources. All of the S. porcinus isolates were beta-hemolytic (wide zones), susceptible to vancomycin, gave positive results for the leucine aminopeptidase and l-pyrrolidonylarylamidase...
متن کاملEvaluation of methods for identification and determination of the taxonomic status of strains belonging to the Streptococcus porcinus-Streptococcus pseudoporcinus complex isolated from animal, human, and dairy sources.
Ninety-seven animal, human, and dairy Streptococcus porcinus or Streptococcus pseudoporcinus isolates in the CDC Streptococcus strain collection were evaluated on the basis of DNA-DNA reassociation, 16S rRNA and rpoB gene sequencing, conventional biochemical and Rapid ID 32 Strep identification methods, and antimicrobial susceptibility testing to determine their taxonomic status, characteristic...
متن کاملCross-reactions of reagents from streptococcal grouping kits with Streptococcus porcinus.
Streptococcus porcinus is usually associated with swine. Because we have received several isolates from human sources that had cross-reacted with commercial group B streptococcal reagents, we examined several commercial kits to determine the extent of this cross-reaction. Fifteen reference and 15 clinical strains of S. porcinus were tested for cross-reactions with group B streptococcal reagents...
متن کاملStreptococcus pseudoporcinus sp. nov., a novel species isolated from the genitourinary tract of women.
Streptococcus strains from animal and human sources identified biochemically as Streptococcus porcinus were investigated by 16S rRNA gene sequencing. The nine human strains isolated between 1997 and 2005 formed a single cluster with more than 2.1% dissimilarity with S. porcinus strains from animal sources. A novel species, Streptococcus pseudoporcinus sp. nov., is proposed.
متن کاملExpression of Recombinant Streptokinase from Streptococcus Pyogenes and Its Reaction with Infected Human and Murine Sera
Objective(s): Streptokinase (SKa) is an antigenic protein which is secreted by Streptococcus pyogenes. Streptokinase induces inflammation by complement activation, which may play a role in post infectious diseases. In the present study, recombinant streptokinase from S. pyogenes was produced and showed that recombinant SKa protein was recognized by infected human sera using Western blot analy...
