Actinobacillus suis 1276/61

Actinobacillus suis 1276/61 is a microaerophilic, rod-shaped bacterium characterized by the presence of flagella, which aids in motility. This organism is notable for its two distinct replicons, suggesting a complex genetic architecture that may contribute to its adaptability and survival in various environments. The genomic sequences for this strain are available under the accessions CP009159.1 and LT906456.1, providing a resource for further research into its genetic and functional traits. As a member of the genus Actinobacillus, A. suis is primarily associated with swine and can be linked to respiratory and systemic infections in pigs. The microaerophilic nature of this bacterium indicates that it thrives in environments with reduced oxygen levels, which is typical of the host's mucosal surfaces. This adaptation may play a crucial role in its pathogenicity and interaction with the host's immune system. Understanding the traits of A. suis, particularly its microaerophilic requirement and motility due to flagella, can offer insights into its ecological niche and potential impact on pig health. The presence of multiple replicons may also suggest a capacity for genetic variation, which can influence its virulence and resistance patterns. Overall, A. suis 1276/61 serves as an important model for studying host-pathogen interactions in swine and may have broader implications for animal health and microbiology research.
