The differences between germ free and specific-pathogen-free mice
WEBWhat are 'germ-free' mice? Truly “germ-free” mice are more properly referred to as “axenic,” meaning that they are free of ALL microorganisms, including those that are typically found in the gut.
Germ-Free Mice - NIH Intramural Research Program
WEBMay 2, 2022 · To find out, NIH scientists are studying germ-free mice that have not been naturally colonized by microorganisms. NIAID is home to one of the few facilities in the United States that houses so-called gnotobiotic mice.

WEBAug 10, 2023 · Germ-free (GF) mice, which are depleted of their resident microbiota, are the gold standard for exploring the role of the microbiome in health and disease; however, they are of limited value in...
Mouse Microbiota Models: Comparing Germ-Free Mice and …
WEBOct 31, 2018 · Germ-free mice are bred in isolators which fully block exposure to microorganisms, with the intent of keeping them free of detectable bacteria, viruses, and eukaryotic microbes. Initially conceptualized by Louis Pasteur in 1885, colonies of germ-free rodents were first established in the 1940s (Yi and Li, 2012 ; Al-Asmakh and Zadjali, 2015 ).

WEBMar 24, 2024 · Germ-free rederivation is the process of creating a GF mouse line from a conventionally or specific-pathogen-free (SPF) housed line, either inbred wild-type mouse lines, or genetically engineered mouse models (GEMM).
What Are Germ-Free Mice and How Are They Sourced?
WEBGerm-free mice are a critical tool to uncover the causal relationship between the microbiome and disease, and to determine the mechanistic basis through which microbes influence the host.
From germ-free to wild: modulating microbiome complexity to
WEBSep 5, 2022 · By feeding GF mice an antigen-free, elemental diet, researchers can begin to unravel the specific influences that dietary, microbial, and environmental antigens (Ag) have on Ag-specific, adaptive...
WEBIn this review, we discuss practical considerations for the design and execution of germ-free and gnotobiotic experiments, including considerations around germ-free rederivation and housing conditions, route and timing of microbial administration, and dosing protocols.
