In a healthy body, organs themselves are typically considered to be free of microbes. This means they are largely sterile environments. For instance, sterile conditions are crucial to avoid infections during organ transplants. However, recent research has started to suggest that even traditionally considered "sterile" areas of the body might contain low levels of microbes or microbial DNA, possibly contributing to the body's functioning in ways that are not yet fully understood.
