The
Rickettsia
bacteria include the aetiological agents for the human spotted fever (SF) disease. In the present
study, a SF group
Rickettsia amblyommii related bacterium was detected in a field collected
Amblyomma sculptum
(
Amblyomma cajennense
species complex) tick from a Brazilian SF endemic site in southeastern Brazil, in the municipality
of Juiz de Fora, state of Minas Gerais. Genetic analysis based on genes
ompA,
ompB and
htrA showed
that the detected strain, named
R. amblyommii str. JF, is related to the species
R. amblyommii.
