Listeria monocytogenes strain FDA605850 74-5

Listeria monocytogenes strain FDA605850 74-5 is a Gram-positive, rod-shaped bacterium that exhibits a chain and single cell arrangement. It is classified as a chemoorganotroph, utilizing organic compounds for energy. This strain is a facultative anaerobe, allowing it to thrive in both aerobic and anaerobic environments. It is mesophilic, with an optimal growth temperature of 30°C, and has a temperature range suitable for growth that aligns with mesophilic conditions. This strain is non-motile and possesses flagella, which may influence its behavior in certain environments, although its mobility is restricted. The bacterium has a single replicon and one membrane, indicating a relatively simple cellular structure. It exists as a free-living organism and has a broad range of hosts including Homo sapiens (humans), Gallus gallus (domestic chickens), various metazoans, amoebae, and Pteropodidae (fruit bats). Listeria monocytogenes is known for its pathogenicity in humans, causing serious health effects such as bacteremia, meningitis, septicemia, gastroenteritis, encephalitis, and listeriosis. It is particularly concerning in foodborne infections, which can lead to severe outcomes, including abortion and acute bacterial meningitis. From an ecological perspective, the presence of Listeria monocytogenes in diverse habitats and its ability to infect various hosts highlight its adaptability and potential impact on both human health and animal populations. This versatility underscores the importance of monitoring and understanding this pathogen in food safety and public health contexts.
