Evaluation of the immunization of camels with vaccine (RB51) in Egypt.

Background: Brucellosis is a highly contagious zoonotic disease caused by an intracellular facultative microorganism termed spp. Control of brucellosis depends on test and slaughter policy as well as vaccination programs.

Aim: Estimation of the cell-mediated immunity (CMI) [total leukocytic count (TLC), phagocytic activity, phagocytic index, interleukin 6 (IL-6), and tumor necrosis factor-alpha (TNF-α)] in camels after vaccination with RB51 using real-time polymerase chain reaction (PCR).
