Glaesserella parasuis strain CCUG 3712

Glaesserella parasuis strain CCUG 3712 is a Gram-negative, rod-shaped bacterium that is associated with hosts, specifically Homo sapiens and Sus scrofa. This organism is characterized as a facultative anaerobe, allowing it to thrive in both aerobic and anaerobic environments, and it is mesophilic, indicating an optimal growth temperature range that aligns with moderate temperatures. One notable trait of G. parasuis is its lack of mobility, despite the presence of flagella. This suggests a potential adaptation to its host-associated lifestyle, relying on host factors for dissemination rather than active movement. The bacterium has a unique cellular structure, consisting of two membranes and a single replicon. Glaesserella parasuis is known to be pathogenic in animals, notably causing Glasser's disease, which can lead to significant health issues in swine. This condition is characterized by a systemic disease that can affect multiple organs and is particularly impactful in young pigs. As a free-living organism, G. parasuis demonstrates a complex biotic relationship with its hosts, which can be both commensal and pathogenic. Understanding the ecological roles of G. parasuis within swine populations can provide insights into disease management and prevention strategies in veterinary medicine.
