Sumario: |
Brucellosis is a major zoonotic disease caused by Brucella species. Historically, the disease
received over fifty names until it was recognized as a single entity, illustrating its protean manifesta-
tions and intricacies, traits that generated conundrums that have remained or re-emerged since they
were first described. Here, we examine confusions concerning the clinical picture, serological diagno-
sis, and incidence of human brucellosis. We also discuss knowledge gaps and prevalent confusions
about animal brucellosis, including brucellosis control strategies, the so-called confirmatory tests,
and assumptions about the primary-binding assays and DNA detection methods. We describe how
doubtfully characterized vaccines have failed to control brucellosis and emphasize how the requisites
of controlled safety and protection experiments are generally overlooked. Finally, we briefly discuss
the experience demonstrating that S19 remains the best cattle vaccine, while RB51 fails to validate its
claimed properties (protection, differentiating infected and vaccinated animals (DIVA), and safety),
offering a strong argument against its current widespread use. These conundrums show that knowl-
edge dealing with brucellosis is lost, and previous experience is overlooked or misinterpreted, as
illustrated in a significant number of misguided meta-analyses. In a global context of intensifying
livestock breeding, such recurrent oversights threaten to increase the impact of brucellosis. |
