Rickettsia prowazekii and its ‘Junk DNA’: The Identification and Characterization of Small RNAs

, 2020
As the etiologic agents of Rocky Mountain spotted fever and epidemic typhus, Rickettsia are obligate intracellular Gram-negative pathogenic bacteria. Genomic sequencing determined that ~24% of the Rickettsia prowazekii genome was noncoding DNA due to ...

Evidence of Exposure to Multiple Zoonotic Pathogens in Humans in Lusaka, Zambia: Insights from Metagenomic Next-Generation Sequencing

Zoonotic Diseases
Zoonotic diseases present a growing public health challenge, particularly in sub-Saharan Africa (SSA) due to close interactions between humans and animals and poor diagnostic capacity. This pilot study investigated human exposure to zoonotic pathogens in

Viability of Rickettsia prowazekii after Rickettsia-Mediated Killing of Gamma Interferon-Pretreated, Macrophage-Like RAW264.7 Cells

, 2016
Rickettsia prowazekii, the bacterium that causes epidemic typhus, mainly grows within endothelial cells and can also infect macrophages. Previous studies showed that pretreatment of cultured, murine macrophage-like RAW264.7 cells with gamma interferon ...
