We report a case of Paenibacillus polymyxa bacteremia in a patient with cerebral infarction. The patient was a 93-year-old female who was admitted to our hospital. On the 4 day after admitted, she had a fever 38.2°C. The result of the blood culture showed a gram positive spore bacillus in the blood culture bottle. As a result of performing 16SrDNA sequence analysis (500bp), it was a close relationship most by 99.26% P. polymlxa of coincidence was found. With a result using api 20E and api 50CH, this bacillus turned out to be P. polymyxa.
The patient had a habit of weeding around her house daily. So we had to take her habit into consideration. We thought she could to get her hands injured. We assumed probably her habit might put her into high risk state of infection of this bacillus. We have supposed this bacillus might be infected with her through her blood.
