Proteomic Analysis of Membrane Blebs of Brucella abortus 2308 and RB51 and Their Evaluation as an Acellular Vaccine

Frontiers in Microbiology, 2019
Membrane blebs are released from Gram-negative bacteria, however, little is known about Brucella blebs. This work pursued two objectives, the first was to determine and identify the proteins in the membrane blebs by proteomics and in silico analysis. The

Induction of Specific Cytotoxic Lymphocytes in Mice Vaccinated withBrucella abortusRB51 [PDF]

Infection and Immunity, 2001
ABSTRACTA safe, more sensitive, nonradioactive, neutral red uptake assay was adopted to replace the traditional51Cr release assay for detection ofBrucella-specific cytotoxic T lymphocyte (CTL) activity. Our studies indicated thatBrucella abortusstrain RB51 vaccination of mice induced specific CTLs against both strain RB51- and strain 2308-infected J774.

Resurgence of Human Brucellosis in Khuzestan Province, Southwestern Iran: Epidemiological Trends From 2017 to 2024

International Journal of Microbiology, Volume 2026, Issue 1, 2026.
Brucellosis is a neglected zoonosis with a considerable disease burden in livestock‐dependent areas. Khuzestan Province, southwestern Iran, exhibits diverse ecological and agricultural landscapes that may drive heterogeneous transmission. Knowledge of recent epidemiological trends is important for targeted control. We aimed to characterize the temporal

Diagnostic Performance of Rose Bengal, Competitive ELISA, and Native Hapten (NH) Assays in S19 Mass‐Vaccinated Cattle in an Endemic Brucellosis Environment

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Controlling bovine brucellosis requires reliable diagnostics and effective vaccination strategies. We evaluated the performance of three serological assays—the rose bengal test (RBT), competitive ELISA (cELISA), and agar gel immunodiffusion (AGID) with native hapten (NH)+lipopolysaccharide (LPS) antigen—following Brucella abortus S19 vaccination under ...

Characterization of recombinant B. abortus strain RB51SOD towards understanding the uncorrelated innate and adaptive immune responses induced by RB51SOD compared to its parent vaccine strain RB51

Frontiers in Cellular and Infection Microbiology, 2011
Brucella abortus is a Gram-negative, facultative intracellular pathogen for several mammals, including humans. Live attenuated B. abortus strain RB51 is currently the official vaccine used against bovine brucellosis in the United States and several other

Antigenic, immunologic and genetic characterization of rough strains B. abortus RB51, B. melitensis B115 and B. melitensis B18. [PDF]

PLoS ONE, 2011
The lipopolysaccharide (LPS) is considered the major virulent factor in Brucella spp. Several genes have been identified involved in the synthesis of the three LPS components: lipid A, core and O-PS.

Immune responses and resistance to brucellosis in mice vaccinated orally with Brucella abortus RB51 [PDF]

Infection and Immunity, 1996
Immune responses and resistance to infection with Brucella abortus 2308 (S2308) were measured in mice following oral or intraperitoneal (i.p.) vaccination with strain RB51 (SRB51). Bacteria persisted in the parotid lymph node for 4 weeks following oral vaccination of mice with 5 x 10(8) or 5 x 10(6) CFU of SRB51.
