"If we are to understand dynamics of bacterial-host cell interactions, we need to investigate the intimate adaptations at the cellular and molecular levels"
Welcome to my personal website. I am a research scientist at CIRAD in the Caribbean Research Centre for Vector-borne diseases (approx. 20 people). We are located on the INRA campus in Petit-Bourg, Guadeloupe and we are part of the ASTRE research unit based in Montpellier. I have worked on numerous whole genome sequencing projects and functional genomics projects for Xanthomonas campestris pv. campestris, X. c. pv. raphani, X. oryzae pv. oryzae, X. o. pv. oryzicola and Ehrlichia ruminantium. My current research interests are directed toward understanding the biology host-intracellular bacteria interactions.
Bacterial pathogens and symbionts exploit a wide array of strategies to facilitate interaction with hosts. For endosymbiotic or intracellular pathogenic bacteria, there is a constant need to manipulate signaling pathways in the eukaryotic mammalian or arthropod host cell. I am particularly interested in the pathways used by intracellular pathogenic Ehrlichia bacteria to enter host cells and create a safe replicating niche. I am also investigating how endosymbiotic Wolbachia bacteria interact with eukaryotic cells. My research encompasses the underlying molecular mechanisms of these processes and the illumination of how these strategies facilitate unique interactions with the host immune system, most notably for immune evasion.
To this aim, I use a systems biology approach that goes from molecular and cellular biology to translational studies with particular emphasis on the interface between the bacterium and its host (vertebrate and invertebrate ; unicellular or multicellular). The unifying theme is the integrated study of infectious strategies of Anaplasmataceae (pathogenic Ehrlichia and symbiotic Wolbachia) in conjunction and communication with each other, their host, and the cellular environment they inhabit.
Findings from this work contribute to understanding the mechanisms of pathogenesis and endosymbiosis as well as advancement of human and animal health interests.
This site contains a more detailed description of my research projects at CIRAD, an introduction to people working with me, reprints of all of my publications, and other useful links.
Infectious Strategies of Anaplasmataceae
My research focus is on how the obligate tick-borne intracellular pathogen Ehrlichia ruminantium (Anaplasmataceae family) manipulates cellular function in order to multiply inside host cells and cause infectious disease.
Heartwater disease caused by E. ruminantium is generally fatal on ruminants and is common in sub-Saharan Africa and in some Caribbean islands. Some human cases have been reported in South Africa. The clinical signs of heartwater (also known as cowdriosis) are caused by an increased vascular permeability and consequent œdema. The symptoms include neurological signs (tremors), respiratory signs (coughing) and systemic signs (fever, loss of appetite).
In the host, E. ruminantium infects endothelial cells and neutrophils, where the pathogen replicates to high numbers in an intracellular vacuole. Ehrlichia produces a Type IV Secretion System (T4SS) to deliver proteins into the host cytoplasm where they can manipulate the host cell machinery and subvert host innate immunity. However, due to a lack of methods for genetic manipulation of the bacterium, Ehrlichia virulence factors remain largely unknown.
Using bioinformatics, genomics, proteomics, cellular and molecular biology approaches, we aim to identify E. ruminantium T4SS substrates and their host targets.
The three major points I am particularly interested in are :
Our studies will provide information about the molecular arsenal used by E. ruminantium and other Anaplasmataceae for successful development inside its host cell. We are also studying the impact of these bacteria on host cells signaling.
Altogether, our research will give new insights on the intimate interaction of Anaplasmataceae with their mammalian or tick host cells and will foster the development of new anti-bacterial molecules.
Entry of E. ruminantium into host cells
Intracellular pathogens have evolved numerous strategies for promoting their entry into host cells, consistent with its essential role in pathogenesis. Yet despite its fundamental importance, Ehrlichial entry remains a largely unexplored research area.
Using microscopy and proteomics, we are characterizing outer membrane proteins involved in E. ruminantium early attachment to host cell and decoy of innate immunity.

Molecular mechanisms to manipulate host processes
We are investigating the role of the Type IV Secretion System of E. ruminantium in bacterial adaptation to the host cell. We want to know how it is expressed along developmental cycle of E. ruminantium between strains of various virulence.
We developed S4TE, a bioinformatic tool in Perl to predict Type IV Secreted Effector proteins of E. ruminantium and to analyse their genomic context. Using molecular and cell biology tools, we are characterizing the function of these effectors.
Inside-out lysis of the host cell by the pathogen
E. ruminantium is also capable of escaping host cells by lysis of its resident vacuole and host plasma membranes, followed by subsequent release of free bacteria into the extracellular compartment. For obligate intracellular pathogens, lysis is a biological process that is tightly regulated. We are using functional genomics and cellular biology to identify key players and signaling pathways involved in this process.
I have additional interests in the broader arenas of microbial pathogenesis. Research topics of particular interest to me are :

2018 - now
M.S. Université des Antilles, Pointe-à-Pitre, FR
Stephanie grew up in Guadeloupe and went to College at Université des Antilles, Pointe-à-Pitre, where she studied biology. After working as research assistant, she joined the group first in 2017 to work on the genetic manipulation of Ehrlichia ruminantium in the frame of a patent consolidation (SATT AxLR grant). Now, using our brand new S4TE2.0 software and cellular biology, Stephanie is studying the molecular determinants of Anaplasmataceae pathogenicity, particularly through the functional characterization of type IV effectomes. Her work should lead to the development of alternative strategies to fight against intracellular pathogenic bacteria and other vector-borne pathogens.
