Journal ArticleDOI

From the discovery of the Malta fever's agent to the discovery of a marine mammal reservoir, brucellosis has continuously been a re-emerging zoonosis

TL;DR: The development of a human vaccine for brucellosis is defined, besides the implementation of control and eradication programs in animals, as a high priority and the pathogenicity for humans of the different Brucella species found in cetaceans and pinnipeds still has to be clearly established.
Journal ArticleDOI

The sheathed flagellum of Brucella melitensis is involved in persistence in a murine model of infection

TL;DR: It is demonstrated that in the early log phase of a growth curve in 2YT nutrient broth, Brucella melitensis expresses genes corresponding to the basal (MS ring) and the distal (hook and filament) parts of the flagellar apparatus.
Journal ArticleDOI

Seroprevalence and potential risk factors for Brucella spp. infection in traditional cattle, sheep and goats reared in urban, periurban and rural areas of Niger.

TL;DR: The seroprevalence varies across strata and animal species with important risk factors including herd size, abortion and transhumance at herd level and age at animal population level and an integrated approach seems appropriate involving all stakeholders working in public and animal health.
Journal ArticleDOI

Bayesian estimation of true prevalence, sensitivity and specificity of indirect ELISA, Rose Bengal Test and Slow Agglutination Test for the diagnosis of brucellosis in sheep and goats in Bangladesh

TL;DR: In this study, three conditionally dependent serological tests for the diagnosis of small ruminant brucellosis in Bangladesh were validated and considered conditional dependence between IELISA and RBT and betweenRBT and SAT was observed among sheep.
