Frederic Delbac

Dr. Frederic Delbac is a researcher at Clermont Auvergne University, affiliated with the Faculty of Biology and the Laboratoire Microorganismes : Génome et Environnement (LMGE), which operates under the auspices of the Centre National de la Recherche Scientifique (CNRS). With a prolific publication record spanning over two decades, Dr. Delbac has established himself as a leading expert in microsporidian biology and honeybee pathology. His research bridges fundamental microbiology with practical applications in apiculture and environmental health.

Dr. Delbac's primary research focus centers on microsporidia, obligate intracellular parasites that infect diverse hosts including honeybees. His work on Nosema ceranae has significantly advanced understanding of how this pathogen affects honeybee physiology, particularly lipid metabolism in the fat body. He has also conducted extensive research on Blastocystis, another protist parasite with implications for human and animal health. His methodological approach integrates genomic, transcriptomic, and molecular techniques to elucidate parasite biology, evolutionary relationships, and host-pathogen interactions. Dr. Delbac's research frequently addresses critical questions in pollinator health, contributing to solutions for honeybee colony losses worldwide.

Analysis of Dr. Delbac's publication trajectory from 2019-2025 reveals evolving research priorities with consistent themes. Early work focused on fundamental aspects of microsporidian biology, particularly the polar tube structure and invasion mechanisms, as evidenced by his 2008 and 2014 book chapters. More recent publications demonstrate a shift toward applied research addressing honeybee health crises, including probiotic strategies against foulbrood, the impact of Nosema ceranae on lipid reserves, and microbiome dysbiosis in pesticide-parasite co-exposures. His 2024-2025 publications indicate growing interest in bioinformatics approaches to microsporidian genomics and paleogenomic studies of microsporidian evolution in environmental contexts.

Dr. Delbac maintains active collaborations across multiple institutions, including international partnerships with researchers in Ireland and the United Kingdom. His work has practical implications for apiculture, environmental monitoring, and understanding host-parasite coevolution. As evidenced by his ongoing research projects and recent publications, Dr. Delbac continues to make significant contributions to parasitology and environmental microbiology.
