Immune Response of Calves Vaccinated with Brucella abortus S19 or RB51 and Revaccinated with RB51.

PLoS ONE, 2015
Brucella abortus S19 and RB51 strains have been successfully used to control bovine brucellosis worldwide; however, currently, most of our understanding of the protective immune response induced by vaccination comes from studies in mice.

Overexpression of Brucella putative glycosyltransferase WbkA in B. abortus RB51 leads to production of exopolysaccharide

Frontiers in Cellular and Infection Microbiology, 2015
Brucella spp. are Gram-negative, facultative intracellular bacteria that cause brucellosis in mammals. Brucella strains containing the O-polysaccharide in their cell wall structure exhibit a smooth phenotype whereas the strains devoid of the ...

Epidemiological Trends and Strain Distribution of Bovine Brucellosis in Vaccinated Industrial Dairy Cattle (2021-2024). [PDF]

Vet Med Int
Brucellosis remains a significant zoonotic disease in Iran, affecting both public health and livestock productivity despite decades of control efforts. This study presents findings from a four‐year nationwide active surveillance program (2021–2024) targeting industrial dairy cattle herds vaccinated with the Brucella abortus RB51 vaccine.
