Lyme disease research studies often require generation of ticks infected with the pathogen Borrelia burgdorferi, a process that typically takes several weeks. Here we demonstrate a microinjection-based tick infection procedure that can be accomplished within hours. We also demonstrate an immunofluorescence method for in situ localization of B. burgdorferi within ticks.

An Ex Vivo Gut Organ Culture System to Study Host-Microbiota Interactions

2025
In this video, we describe the methodology for setting up an ex vivo gut organ culture system to study the interactions between mouse intestinal tissue fragments and specific gut bacteria. The device consists of two pairs of input-output ports, the first connecting the intestinal tissue lumen and supplying the specific bacterial suspension into it, and the second continuously supplying media to the device's wells to maintain ex vivo tissue viability.
FAQs
Detailed inspection connects visible structure with digestive function. Examining length, compartments, tissue layers, contents, and associated blood vessels helps relate regional organization to ingestion, digestion, absorption, and waste elimination. This structural evidence also supports comparison among specimens and discussion of how anatomical arrangements reflect biological function.
Compartments and tissue layers provide distinct structural features for organizing observations. Their arrangement helps students or researchers describe how the digestive tract is internally and regionally organized rather than treating it as a single undifferentiated tube. Recording these features supports anatomical comparison and consideration of adaptations associated with digestive activity.
Associated blood vessels and gut contents add context to the gut’s visible anatomy. Vessels show relationships between the digestive tract and surrounding structures, while contents provide an observable feature for describing the tract during examination. Together with length and compartments, these observations create a more complete record for biological study.
The procedure begins with carefully opening the abdominal region, followed by isolating the gut from nearby structures. Researchers or students then inspect its length, compartments, tissue layers, contents, and associated blood vessels. Careful observation throughout each stage helps preserve anatomical relationships and produces a reliable description of the specimen.
Specimen handling should be careful, and observations should be accurate and systematic. The abdominal region is opened cautiously, the gut is isolated without losing its relationships with surrounding organs, and visible features are inspected before conclusions are drawn. Ethical laboratory practice remains part of the procedure, particularly in educational biology settings.
In biology education, the technique provides direct study of digestive anatomy and supports learning about structural adaptations. In research, it can contribute to comparative anatomy and investigations involving development, physiology, nutrition, and gastrointestinal disease. Its value comes from linking observed organization with broader questions about digestive structure and function.
