Pseudomonas fluorescens strain Ps_22

Pseudomonas fluorescens strain Ps_22 is a Gram-negative, rod-shaped bacterium that exhibits mobility due to the presence of flagella. It is classified as a heterotrophic aerobe, thriving in various habitats and ideally growing at an optimal temperature of 25°C within a mesophilic temperature range. This strain possesses a single replicon and is characterized by a double membrane structure, which is typical of Gram-negative bacteria. In terms of its ecological relationships, Pseudomonas fluorescens strain Ps_22 is free-living and has been identified in association with a diverse array of hosts, including Homo sapiens, various Metazoa, and multiple plant species such as Triticum aestivum, Solanum tuberosum, Solanum lycopersicum, and Hordeum vulgare. Additionally, it has been associated with several amphibian species and plants like Psidium guajava and Catharanthus roseus, indicating its widespread presence in both terrestrial and aquatic ecosystems. The strain is notable for its capacity to cause bacterial infections in animals, highlighting its potential pathogenicity. This characteristic suggests that while Pseudomonas fluorescens strain Ps_22 plays an important role in the environment as a free-living bacterium, it also possesses the ability to impact animal health, including that of humans. Understanding the ecological niches and interactions of this strain can provide insight into its role in microbial communities and its implications for health and disease in various organisms.
