With S. anginosus blood stream infections it has been widely reported that the source is often from an abscess. In one series of 51 cases of Strep milleri group bacteremia, 6 were associated with abscesses. [5] Pyogenic liver abscess is associated with S. anginosus and in studies in the 1970s was reported to be the most common cause of hepatic ...
The anginosus group streptococci are members of the viridans streptococci group. [1] They have been implicated as etiologic agents in a variety of serious purulent infections, but because of their heterogeneous characteristics, these organisms may be unrecognized or misidentified by clinical laboratorians.

Clostridium botulinum; Note: Botulism is not an infection by Clostridium botulinum but caused by the intake of botulinum toxin. Botulism (and Infant botulism) Enzyme-linked immunosorbent assays (ELISAs), electrochemiluminescent (ECL) tests Botulism antitoxin and supportive care No Sabiá virus: Brazilian hemorrhagic fever: No Brucella species ...
This group includes S. equi, which causes strangles in horses, [19] and S. zooepidemicus — S. equi is a clonal descendant or biovar of the ancestral S. zooepidemicus — which causes infections in several species of mammals, including cattle and horses.
The S. anginosus group, occasionally termed “Streptococcus milleri group” (SMG) display hemolytic and serologic diversity, yet share core physiological traits. Though the three members of the SMG are phenotypically diverse, one common trait they share is the mechanism of producing the metabolite diacetyl , which contributes to generating a ...
The virulence of S. pseudintermedius is an area of on going research and has many unknowns. [40] The virulence factors carried by S. pseudintermedius vary between strains and do not determine if it will cause an infection. Rather, infection is a result of an animal's immune status, [1] environment, and genetics. [39]
However, it can frequently cause purulent infections in other parts of the body. [3] DNA homology studies and 16S rRNA sequence analysis demonstrate S. constellatus belongs to the Streptococcus anginosus group (milleri group) along with Streptococcus intermedius and Streptococcus anginosus. [4]
Other strains of streptococci can cause subacute endocarditis as well. These include streptococcus intermedius, which can cause acute or subacute infection (about 15% of cases pertaining to infective endocarditis). [7] Enterococci from urinary tract infections and coagulase negative staphylococci can also be causative agents. [5]
