Streptococcus acidominimus is a species of nonmotile, gram-positive facultative anaerobic bacteria that is a member of the viridans group streptococci (VGS). It is a rare pathogen in humans.[1][2]
History
It was first isolated from bovines sources in 1922 by Ayers and Mudge.[2]
Infection
It is considered to be a common bacterial pathogen in veterinary medicine but is rarely pathogenic in humans.[2] S. acidominimus is a major cause of infection for people who are critically ill. Due to the uncommonness and rarity of obtaining it in clinical bacteriology,[3] S. acidominimus infections and limited cases, it is difficult to assess its epidemiologic and clinical significance. This also means that identifying S. acidominimus as a causative species is difficult.[1] In recent years, S. acidominimus has been showing increased resistance to antimicrobial agents such as beta-lactams which is unusual since this species is usually sensitive to them.[4]
In humans, this species have been reported in cases of pneumonia, pericarditis, meningitis, otitis median, sepsis, endocarditis and brain abscess.[1]
Treatment
Streptococcus acidominimus has been shown to be sensitive to antimicrobial agents.
