Glaesserella parasuis strain NCTC4557

Glaesserella parasuis strain NCTC4557 is a Gram-negative bacterium primarily associated with the host, notably affecting Sus scrofa (pigs) and occasionally Homo sapiens. This organism has a rod shape and is characterized by the presence of flagella, indicating potential motility, although it is described as non-motile. G. parasuis is an aerobe and facultative anaerobe, allowing it to thrive in varying oxygen conditions, and it is mesophilic, indicating an optimal growth temperature range typical of warm-blooded hosts. This strain has a single replicon and possesses a double membrane structure, which is common among Gram-negative bacteria. G. parasuis is known for its pathogenicity in animals, particularly causing Glasser's disease, a serious condition affecting swine characterized by inflammation of serous membranes. The biotic relationship of G. parasuis is free-living, suggesting it can survive independently in its environment, although it is primarily associated with its hosts. The pathogenic capabilities of G. parasuis highlight its ecological importance within swine populations, as it can lead to significant health challenges in livestock. Understanding the traits and behaviors of this strain can provide insights into its role in animal health and disease dynamics, particularly in agricultural settings where pigs are a vital resource. Further research into G. parasuis could inform strategies for managing its impact on swine health and welfare.
