Neisseria lactamica 020-06

Neisseria lactamica 020-06 is a Gram-negative, aerobic cocci bacterium that typically exists in pairs. It is classified as a chemoheterotroph, meaning it derives its energy from organic compounds. This species is non-motile and does not produce flagella, which is consistent with its free-living lifestyle. N. lactamica is mesophilic, with an optimal growth temperature of 35°C, and it thrives within a temperature range suitable for many human-associated microorganisms. The organism possesses a single replicon and is characterized by having two membranes, a common feature among Gram-negative bacteria. Importantly, N. lactamica 020-06 does not exhibit pathogenicity, suggesting that it is not associated with disease in humans, its primary host. This non-pathogenic nature is notable as it enables N. lactamica to coexist within the human microbiome without causing harm. The ecological role of Neisseria lactamica can be significant in maintaining microbial balance within its habitat. By residing in the human nasal cavity and throat, it may contribute to the competitive exclusion of pathogenic species, thereby playing a protective role. Its presence in multiple habitats highlights its adaptability and potential significance in various ecosystems, particularly in relation to human health. The accession number for this strain is NC_014752.1, which can be used for further genomic studies and comparisons.
