Listeria monocytogenes strain FDAARGOS_778

Listeria monocytogenes strain FDAARGOS_778 is a Gram-positive, rod-shaped bacterium categorized as a facultative anaerobe. It has a characteristic cell arrangement observed in chains or singles and lacks mobility, despite possessing flagella. This strain is classified as a chemoorganotroph, obtaining its energy from organic compounds, and thrives optimally at a temperature of 30°C, fitting within a mesophilic temperature range. L. monocytogenes is known for its pathogenic potential in humans, as it can cause serious health conditions including bacteremia, meningitis, gastroenteritis, and listeriosis. The bacterium is particularly concerning in immunocompromised populations and can lead to severe outcomes such as abortion and bacterial sepsis. Its biotic relationships are diverse, as it is a free-living organism capable of infecting a range of hosts including Homo sapiens, Gallus gallus (domestic chickens), various Metazoa, Amoeba, and Pteropodidae (fruit bats). The strain has a single replicon and one membrane, and it does not undergo sporulation. The presence of this strain in various habitats highlights its adaptability and ecological versatility. Understanding the environmental and biological contexts in which L. monocytogenes thrives can provide insights into its transmission pathways, particularly in the context of foodborne infections, which remain a significant public health challenge.
