In this Research Topic of Frontiers in Cellular and Infection Microbiology journal, We have tried to emphasise studies on blood microbiota and its different effects on health and disease. Blood acts as a liquid medium carrying the elements necessary for host life. In recent years, the concept of human blood microbiota has been developed and this has caused serious debates as it may shelve the idea that “blood is a sterile environment” that has been in existence for years. Although there are different hypotheses that the blood microbiota originates from the gut microbiota, its origin is not clearly understood because it contains different phyla (Castillo et al., 2019). In today’s medicine, where faecal microbiota transplantation is being considered for treatment, blood transplantation is much more easily feasible. If the effects of the blood microbiota on health and disease can be demonstrated, intervention here may be possible (Almeida et al., 2022). Therefore, the aim of this Research Topic was to provide an up-to-date summary on recent findings on the role of the blood microbiota and to explore relationships between the blood microbiota and diseases. This Research Topic also acted as a key initiative towards facilitating a discussion on the role of blood microbiota and its interactions with the immune system during health and disease.
