Conclusions
This study showed a wide diversity of B. melitensis bv3 genotypes
among different ruminant species in Egypt and the risk of uncontrolled
local and international animal movement. It also indicates that this is
a potentially major cause of failure for national control measures for
brucellosis. Our novel findings on the biology and epidemiology ofBrucella spp. is important for reviewing the current strategies
for the control of brucellosis in Egypt and other countries with similar
production systems. It will also support the selection of the proper
vaccinal strain originating from the predominant genotype.
