Survival of a bacterioferritin deletion mutant of Brucella melitensis 16M in human monocyte-derived macrophages

Infect Immun. 1997 Oct;65(10):4337-40. doi: 10.1128/iai.65.10.4337-4340.1997.

Abstract

A bacterioferritin (BFR) deletion mutant of Brucella melitensis 16M was generated by gene replacement. The deletion was complemented with a broad-host-range vector carrying the wild-type bfr gene, pBBR-bfr. The survival and growth of the mutant, B. melitensis PAD 2-78, were similar to those of its parental strain in human monocyte-derived macrophages (MDM). These results suggest that BFR is not essential for the intracellular survival of B. melitensis in human MDM.
