  • COMMENTS:
    • When asked for a cause of fibrinosuppurative valvulitis (you can call it vegetative valvular endocarditis but that's not a good morphologic), you should always say Staph, strep, and coliforms. Some species have their own species of Streptococci, and in pigs, it is Strep suis. Not to say this can't be Staph (especially in lab animals with indwelling catheters or implants), coliform, or Hemophilus parasuis, but Streptococcus suis is a good intial thought...
