Streptococcus intermedius strain A2

Streptococcus intermedius strain A2 is a Gram-positive, facultative anaerobic cocci that is primarily found in the oral cavity, including dental plaques and the mouth. Its cell arrangement typically appears in pairs or chains. This strain possesses a single replicon and is characterized by the presence of flagella. This microorganism is associated with a variety of health effects, particularly in humans (Homo sapiens) and rabbits (Oryctolagus cuniculus). It can lead to serious conditions such as bacteremia, brain abscesses, and infective endocarditis, among others. Other significant health impacts include liver abscesses, osteomyelitis, periodontitis, and intracranial suppuration. The strain is known to be involved in deep infections, including deep neck infections and cervical lymphadenitis, indicating its potential for invasive pathogenicity. Streptococcus intermedius strain A2’s ability to thrive in both aerobic and anaerobic environments allows it to inhabit diverse niches within the host, particularly in the oral cavity where it can contribute to dental diseases. Its pathogenic potential is underscored by its capacity to cause various abscesses and systemic infections. The strain's presence in brain abscesses suggests a specific ecological role in human health, particularly in conditions where the normal barrier to infection is compromised. Understanding its behavior and effects in these habitats may provide insights into managing infections associated with this organism.
