- One of the most common causes of vegetative valvular endocarditis in a variety of domestic species is Streptococcus. Many species have their own particular species that will do this: pigs (S. suis), dogs (S. canis), primates,guinea pigs and humans (S. pneumoniae), horse (S. equi) and even opossums (S. viridans). It is a common pathogen whose exotoxins cause an outpouring of fibrin in potential spaces, and research into human strains of Streptococcus has identified specific cardiopathic epitopes of the streptococcal M protein. Streptococcus suis has also caused endocarditis in cattle and humans.
