RT   "The sheathed flagellum of Brucella melitensis is involved in persistence
RT   in a murine model of infection.";
RL   Cell. Microbiol. 7:687-698(2005).
CC   -!- FUNCTION: The flagellum is required to cause a persistent disease in a
CC       murine model of infection. {ECO:0000269|PubMed:15839898}.
CC   -!- SUBCELLULAR LOCATION: Bacterial flagellum basal body {ECO:0000250}.
CC   -!- INDUCTION: Expressed at the onset of the exponential phase (after 4, 8
CC       and 12 hours of culture) but not at later time points.
CC   -!- DISRUPTION PHENOTYPE: A flgE mutant is attenuated in a murine model of
CC       infection. Four weeks after infection, the number of cfu per spleen
CC       from mice infected with the mutant is significantly lower than the
CC       number from mice infected with the wild-type.
CC       {ECO:0000269|PubMed:15839898}.
CC   -!- SIMILARITY: Belongs to the flagella basal body rod proteins family.
CC       {ECO:0000305}.
CC   -!- CAUTION: Despite the presence of a stop codon in position 243 in the
CC       fliF gene and in position 127 in the flhA gene, it has been shown that
CC       B.melitensis is able to express genes corresponding to the M ring, the
CC       hook and the filament of the flagellar apparatus in the early log phase
CC       of growth in 2YT broth. Under these conditions, a polar and sheathed
CC       flagellar structure is visible by transmission electron microscopy.
CC       {ECO:0000305}.
