All animal procedures described here must be conducted in accordance with institutional animal ethics guidelines and approved by IACUC. All procedures must follow the principles of the 3Rs—Replacement, Reduction, and Refinement—and must be performed by trained personnel. Blood collection is a common procedure in swine research and clinical studies. The choice of sampling site depends on the animal's age, body size, the volume of blood required, the study objectives and approved IACUC...

This video describes a swab-based technique to isolate viable commensal bacteria from the ocular conjunctiva. The technique can be used to profile the commensal bacterial microbiome of the conjunctiva, which plays a defensive role against pathogens.
FAQs
The swab gathers a mixed sample containing epithelial cells, secretions, and microorganisms from the cloacal surface. This combination can provide material for examining infectious agents while also preserving information about host-associated biological conditions. Because several material types are collected together, the sample can support investigations of pathogen presence, microbial communities, and host responses within the same sampling approach.
Gentle insertion and rotation help the sterile swab contact the cloacal surface sufficiently to collect epithelial cells, secretions, and microorganisms. The technique is minimally invasive because sampling does not require tissue removal. Careful handling is important for obtaining representative biological material while maintaining the intended low-impact approach across birds, reptiles, amphibians, and other animals with a cloaca.
After collection, the swab is placed in appropriate transport medium before laboratory analysis. This step provides the designated medium for handling the collected material between sampling and testing. Its use is part of the sample workflow and supports subsequent analysis by culture or molecular assays, allowing the collected biological material to proceed to pathogen detection or related investigations.
Collected material can be examined through culture or molecular assays, two laboratory approaches identified for detecting pathogens in the sample. Culture provides a route for analyzing organisms through laboratory growth, whereas molecular assays analyze the sample using pathogen-related molecular information. These options make cloacal sampling useful for infectious-disease surveillance and experimental infection studies.
The workflow consists of using a sterile swab, gently inserting it into the cloaca, rotating it to collect biological material, and placing it in appropriate transport medium. The handled sample is then available for laboratory analysis. These steps connect minimally invasive sampling with downstream culture or molecular testing and help standardize collection across relevant animal groups.
Researchers can use this sampling approach for pathogen detection, infectious-disease surveillance, and experimental infection studies. It is also suited to investigating host immune responses, shedding patterns, and microbial communities. Wildlife and veterinary work benefit from the minimally invasive format, while repeated or comparative sampling can help examine how infection-related biological material changes across study settings.
Cloacal samples can support questions about whether pathogens are present, how infectious material is shed, and how microbial communities are associated with the sampled site. They can also contribute to investigations of host immune responses. In immunology and infection research, these outcomes connect laboratory detection with broader observations about host and microorganism interactions.
