Brucella sp. sequence‑type 27 associated with abortion in dwarf sperm whale Kogia sima
(Springer Link, 2021-05-18)
A dwarf sperm whale Kogia sima stranded alive along the Central Pacifc Coast of Costa Rica. The whale, handled by tourists and local inhabitants, was weak, had buoyancy difculties, and eventually aborted and died, showing ...
A Sinorhizobium meliloti and Agrobacterium tumefaciens ExoR ortholog is not crucial for Brucella abortus virulence
(PLOS ONE, 2021-08-13)
Brucella is a facultative extracellular-intracellular pathogen that belongs to the Alphaproteo-
bacteria class. Precise sensing of environmental changes and a proper response mediated
by a gene expression regulatory ...
Persistence of Brucella abortus lineages revealed by genomic characterization and phylodynamic analysis
(PLOS Neglected Tropical Diseases, 2020-04-14)
Brucellosis, caused by Brucella abortus, is a major disease of cattle and humans worldwide distributed. Eradication and control of the disease has been difficult in Central and South America, Central Asia, the Mediterranean ...
A bvrR/bvrS Non-Polar Brucella abortus Mutant Confirms the Role of the Two-Component System BvrR/BvrS in Virulence and Membrane Integrity
(MDPI, 2023-08-05)
Brucella abortus is a bacterial pathogen causing bovine brucellosis worldwide. This facultative extracellular–intracellular pathogen can be transmitted to humans, leading to a zoonotic disease.
The disease remains a public ...
Virulent Brucella nosferati infecting Desmodus rotundus has emerging potential due to the broad foraging range of its bat host for humans and wild and domestic animals
(American Society for Microbiology, 2023-07-05)
Desmodus rotundus, vampire bats, transmit dangerous infections, and
brucellosis is a hazardous zoonotic disease, two adversities that coexist in the subtropical
and tropical areas of the American continent. Here, we ...
If You're Not Confused, You're Not Paying Attention: Ochrobactrum Is Not Brucella
(American Society for Microbiology, 2023-07-03)
Bacteria of the genus Brucella are facultative intracellular parasites that cause brucellosis, a severe animal and human disease. Recently, a group of taxonomists merged the brucellae with the primarily free-living, ...
A sensor histidine kinase from a plant-endosymbiont bacterium restores the virulence of a mammalian intracellular pathogen
(Elsevier, 2023-11-08)
Alphaproteobacteria include organisms living in close association with plants or animals. This interaction relies partly on orthologous two-component regulatory systems (TCS), with sensor and regulator proteins modulating ...
