Effect of levamisole administration on immunogenic and protective capacity of Brucella abortus RB51

National Journal of Physiology, Pharmacy and Pharmacology, 2018
Background: Brucella abortus strain RB51 is a rough strain that was derived after multiple passages of virulent strain 2308. Levamisole, a potent anthelmintic that is widely used in veterinary medicine, is also known as an immune stimulant.

SAFETY OF BRUCELLA ABORTUS STRAIN RB51 VACCINE IN NON-TARGET UNGULATES AND COYOTES [PDF]

Journal of Wildlife Diseases, 2002
Brucellosis is endemic in free-ranging elk (Cervus elaphus) and bison (Bison bison) in the Greater Yellowstone Area (GYA; USA). It is possible that an oral brucellosis vaccine could be developed and disseminated in the GYA to reduce disease transmission. Should this occur, non-target species other than elk and bison may come in contact with the vaccine

Safety of B. abortus rough mutant strain RB51 administration in Buffalo cows

Italian Journal of Animal Science, 2010
The objective of this study was to determine if B. abortus rough mutant strain RB51 is eliminated in Buffalo milk. Five milk buffaloes were inoculated with the triple of the recommended calfhood dose (3.0 – 10.2 x 1010 cfu/ml) of B.

Overexpression of wbkF gene in Brucella abortus RB51WboA leads to increased O-polysaccharide expression and enhanced vaccine efficacy against B. abortus 2308, B. melitensis 16M, and B. suis 1330 in a murine brucellosis model.

PLoS ONE, 2019
Brucella abortus RB51 is an attenuated, stable, spontaneous rough mutant derived in the laboratory from the virulent strain B. abortus 2308. Previous studies discovered that the wboA gene, which encodes a glycosyltransferase required for synthesis of the
