Abiotrophia defectiva ATCC 49176

Abiotrophia defectiva ATCC 49176 is a microaerophilic bacterium, meaning it requires reduced levels of oxygen for optimal growth. This characteristic places it in a specific ecological niche where oxygen concentration is lower than that found in the atmosphere. The organism possesses two replicons, which can suggest a degree of genetic complexity or adaptability. The strain's genetic information is accessible through the following accession numbers: ACIN00000000.3 and NZ_ACIN00000000, which indicate that its genomic data has been sequenced and made available for further research. This data can facilitate studies on its metabolic pathways, pathogenic potential, and responses to environmental changes. As a microaerophile, Abiotrophia defectiva may play a role in specific environments where oxygen levels are limited, such as in certain human body sites or in particular ecological habitats. Its unique oxygen requirement and genetic characteristics could contribute to its survival and persistence in such conditions, potentially influencing microbial community dynamics. Understanding these traits could provide insights into its ecological interactions and its role in health and disease, particularly in relation to its pathogenicity in humans.
