 An overgrowth of "Prevotella" and a reduction of "Lactobacillus" have been correlated with the onset of osteomyelitis in mice.The reduction of "Prevotella" in model mice led to an increase of "Lactobacillus" showing a protection effect against osteomyelitis.Thus, changes in the microbiota "Prevotella" may be related to the development of osteomyelitis.
