Rickettsia prowazekii str. Madrid E

Rickettsia prowazekii strain Madrid E is a gram-negative bacterium characterized by its bacilli shape and aerobic oxygen requirement. This organism is non-motile and possesses flagella, which may play a role in its unique physiological adaptations. R. prowazekii is mesophilic, thriving in moderate temperature ranges. This bacterium is associated with host environments, indicating a symbiotic relationship, which is crucial for its survival and pathogenicity. R. prowazekii is pathogenic, known to cause epidemic typhus in humans, and is classified as nonsporulating, meaning it does not form spores as a survival mechanism. The bacterium has a singular replicon and is distinguished by its two membranes, a feature typical of gram-negative bacteria. These membranes contribute to its structural integrity and may influence its interactions with the host immune system. Rickettsia prowazekii strain Madrid E is cataloged under accession NC_000963.1, which provides a reference for genetic and genomic studies. Understanding the biological characteristics of this bacterium enhances our knowledge of its ecological role and pathogenic potential. The symbiotic relationship it forms with its host is vital not only for its survival but also underscores the significance of host-associated microorganisms in disease dynamics.
