Genetic Diversity, Phylogenetic Structure, and Assessment of the Zoonotic Potential of Coxiella burnetii Strains Circulating in Africa: Review Study

Mama Agnès Tea, Albert Sourou Salko, Abdoulaye Barry, Éric Ghigo

Coxiella burnetii, the bacterium responsible for Q fever, is an obligate intracellular pathogen. Q fever is a global zoonotic disease, except in New Zealand, and has significant economic and public health consequences. In Africa, although studies on human and animal seroprevalence are …

Genomic evolution and adaptation of arthropod-associated Rickettsia

Khalid El Karkouri, Éric Ghigo, Didier Raoult, Pierre‐Edouard Fournier

Rickettsia species are endosymbionts hosted by arthropods and are known to cause mild to fatal diseases in humans. Here, we analyse the evolution and diversity of 34 Rickettsia species using a pangenomic meta-analysis (80 genomes/41 plasmids). Phylogenomic trees showed that Rickettsia spp. …

Culturomics revealed the bacterial constituents of the microbiota of a 10-year-old laboratory culture of planarian species S. mediterranea

Luis Johnson Kangale, Didier Raoult, Pierre‐Edouard Fournier, Éric Ghigo

The planarian species Schmidtea mediterranea is a flatworm living in freshwater that is used in the research laboratory as a model to study developmental and regeneration mechanisms, as well as antibacterial mechanisms. However, the cultivable microbial repertoire of the microbes comprising its …

Chryseobacterium schmidteae sp. nov. a novel bacterial species isolated from planarian Schmidtea mediterranea

Luis Johnson Kangale, Didier Raoult, Éric Ghigo, Pierre‐Edouard Fournier

Abstract Marseille-P9602 T is a Chryseobacterium -like strain that we isolated from planarian Schmidtea mediterranea and characterized by taxono-genomic approach. We found that Marseille-P9602 T strain exhibits a 16S rRNA gene sequence similarity of 98.76% with Chryseobacterium scophthalmum LMG 13028 T strain, …

Artificially altered gravity elicits cell homeostasis imbalance in planarian worms, and cerium oxide nanoparticles counteract this effect

Alessandra Salvetti, Andrea Degl’Innocenti, Gaetana Gambino, Jack J. W. A. van Loon et autres

Gravity alterations elicit complex and mostly detrimental effects on biological systems. Among these, a prominent role is occupied by oxidative stress, with consequences for tissue homeostasis and development. Studies in altered gravity are relevant for both Earth and space biomedicine, but their …

The Act of Controlling Adult Stem Cell Dynamics: Insights from Animal Models

Meera Krishnan, Sahil Kumar, Luis Johnson Kangale, Éric Ghigo et autres

Adult stem cells (ASCs) are the undifferentiated cells that possess self-renewal and differentiation abilities. They are present in all major organ systems of the body and are uniquely reserved there during development for tissue maintenance during homeostasis, injury, and infection. They do …

Metabacillus schmidteae sp. nov., Cultivated from Planarian Schmidtea mediterranea Microbiota

Luis Johnson Kangale, Didier Raoult, Éric Ghigo, Pierre‐Edouard Fournier

Taxonogenomics combines phenotypic assays and genomic analysis as a means of characterizing novel strains. We used this strategy to study Marseille-P9898T strain, an aerobic, motile, Gram-negative, spore-forming, and rod-shaped bacterium isolated from planarian Schmidtea mediterranea. Marseille-P9898T is catalase-positive and oxidase-negative. The major …
