Abstract
Objective To investigate whether spinal cord injury (SCI) will cause bacteria transfer to other organs and induce these organs infection in mice.
Methods SPF C57BL/6J mice were randomly divided into two groups: SCI group (n = 6) and sham operation group (n = 6). Mice were anesthetized with 1.25% tribromoethanol and performed with a moderate contusion (0.5 mm/0.4 s) injury at the spinal cord T10 with an LSA-Vibraknife. One week after the operation, the spinal cord, liver, and lung tissues in each
group of mice were collected for detection of the bacterial DNA using polymerase chain
reaction (PCR) to determine.
Results It turns out that positive 16s rRNA bands were detected in the spinal cord, the liver, and lungs after spinal cord injury. However, no positive bands were measured in the sham group.
Conclusion The infection of the liver and the lung results suggest that the bacteria of the intestine may enter the blood stream after SCI and cause the infection in these two organs. While spinal cord infection may cause from the injury itself or from translocation of intestinal bacteria.
