Aggregatibacter aphrophilus ATCC 33389 strain NCTC 5906

Aggregatibacter aphrophilus ATCC 33389 strain NCTC 5906 is a Gram-negative bacterium that is classified as mesophilic, indicating that it thrives at moderate temperatures. This organism has a rod shape and is characterized by the presence of flagella, although it is noted to be non-motile. It possesses a single replicon and two membranes, typical features of Gram-negative bacteria. The ecological niche of A. aphrophilus is primarily host-associated, indicating a relationship with a host organism, yet it is also described as free-living. This dual nature suggests that it may play roles both in symbiotic relationships with hosts and in the broader environment. A. aphrophilus is facultatively anaerobic, meaning it can survive in both aerobic and anaerobic conditions. This adaptability may contribute to its survival in diverse environments, particularly within host-associated habitats where oxygen levels can fluctuate. The accession number for this strain is NZ_LR134327.1, which allows researchers to access genetic and genomic information for further studies. Understanding the characteristics of A. aphrophilus ATCC 33389 may provide insights into its role in health and disease, particularly in relation to its host interactions.
