Brucella - Medical Microbiology - NCBI Bookshelf
A culture can be identified as belonging to the genus Brucella on the basis of colonial morphology, staining and slide agglutination with anti-Brucella serum, smooth or rough. Further classification is best done in a specialized laboratory.
species. Brucellosis is a commonly acquired laboratory infection; all work on suspect Brucella spp. cul-tures should be performed at a minimum under BSL2 conditions with BSL3 practices. Growth on BA at 48 h. Growth on CA at 48 h.
The following characteristics are common to Brucella (Ochrobactrum) species and can be used to quickly rule out select agent Brucella species and non-select agent causes of brucellosis: • Rapid colony growth on MacConkey agar (>0.5 mm after 24 h). • Mucoid colony morphology.

The analysis of the flagellum structure in B. melitensis by transmission electron microscopy (TEM) has identified several characteristics of the sheathed flagella of other species, although little is known about flagellar sheaths in bacteria; indeed, Brucella is the only rhizobium that produces a sheathed flagellum [42,43].
