Reassessment of the genetic basis of natural rifampin resistance in the genus Rickettsia

MicrobiologyOpen, Volume 13, Issue 4, August 2024.
Contrary to previous studies, the natural resistance of Rickettsia, a genus of intracellular bacteria, to the antibiotic rifampin is not solely due to the Leu‐973 residue in the RNA polymerase β subunit. Abstract Rickettsia, a genus of obligate intracellular bacteria, includes species that cause significant human diseases.

Prevalence and risk factors for Q fever, spotted fever group rickettsioses, and typhus group rickettsioses in a pastoralist community of northern Tanzania, 2016–2017

Tropical Medicine &International Health, Volume 29, Issue 5, Page 365-376, May 2024.
Abstract Background In northern Tanzania, Q fever, spotted fever group (SFG) rickettsioses, and typhus group (TG) rickettsioses are common causes of febrile illness. We sought to describe the prevalence and risk factors for these zoonoses in a pastoralist community.
