EUCAST will during 2023, based on the work of theEMERGE AST Working Group, strive to publish clinical breakpoints and disk diffusion correlates for Brucella melitensis and Bacillus anthracis.

Through the joint effort of the group and EUCAST, MIC and zone diameter distributions are now available. ECOFFs are under development and will be available soonest.

[relayed from abstract] This paper reports 2 cases of brucellosis in male patients who were hospitalized in distinct towns of French Guiana, an overseas territory of France located on the northeastern shore of South America. Both men were citizens of Brazil working as clandestine goldminers in the deep Amazonian rainforest.

Characterization of the 2 bacterial isolates revealed that they represent a potential new species of Brucella: Brucella amazionensis.
