The Brucella Cell Envelope - PMC - National Center for …
2023年9月9日 · The cell envelope is a multilayered structure that insulates the interior of bacterial cells from an often chaotic outside world. Common features define the envelope across the bacterial kingdom, but the molecular mechanisms by which cells build and regulate this critical barrier are diverse and reflect the evolutionary histories of bacterial ...
Brucella - Medical Microbiology - NCBI Bookshelf
In humans, the tissue lesions produced by Brucella species consist of minute granulomas that are composed of epithelioid cells, polymorphonuclear leukocytes, lymphocytes and some giant cells. In cases of infection with B melitensis these granulomas are particularly small although the toxemia associated with this organism is great.
Brucella – Virulence Factors, Pathogenesis and Treatment - PMC
Brucella is an intracellular pathogen, during an infection it survives and multiplies in macrophages; the bacteria adapt to the acidic pH, low levels of oxygen, and low levels of nutrients (Kőhler et al., 2002). Lipopolisaccharide (LPS) is an essential element of structure building in each Gram-negative bacterial cell.
The Brucella Cell Envelope - Annual Reviews
We review distinct features of the Brucella envelope, highlighting a conserved regulatory system that links cell cycle progression to envelope biogenesis and cell division. We further discuss recently discovered structural features of the Brucella envelope that ensure envelope integrity and that facilitate cell survival in the face of host ...
Brucella spp noncanonical LPS: structure, biosynthesis, and …
2006年3月23日 · Here, we review i) Brucella LPS structure; ii) Brucella genome, iii) genes involved in LPS biosynthesis; iv) the interaction between LPS and innate immunity. Brucella spp. are facultative intracellular pathogens that have the ability to survive and multiply in professional and non-professional phagocytes, and cause abortion in domestic animals ...
Brucella melitensis - microbewiki - Kenyon College
2011年7月7日 · Cell structure and metabolism Brucella is a Gram-negative coccobacilli pathogenic bacteria that adapts to an intracellular lifestyle, is non-spore-forming and is non-motile. These organisms are mainly aerobic but some may require an atmosphere containing about 5-10% of carbon dioxide.
Editorial: Pathogenomics of the Genus Brucella and Beyond
2021年7月7日 · Brucella Cell Envelope and Surface Structures. Three papers focus on the role and properties of lipopolysaccharide (LPS) and lipids of the Brucella cell envelope. Brucella LPS plays a major role in virulence impairing recognition by the innate immune system and delaying immune responses (Roop et al., 2021). The LPS core is a branched structure ...
Structure and properties of the outer membranes of Brucella ... - PubMed
This article reviews the structure and topology of the main components (lipopolysaccharide, native hapten polysaccharide, free lipids and proteins) of the outer membranes of Brucella abortus and B. melitensis, as well as some distinctive properties (permeability and interactions with cationic peptides) of these membranes.
