Many foreign reports have shown that it can cause a variety of parenteral infections such as urinary tract infections, traumatic infections, meningitis, peritonitis and septicemia. Now we from the pleural fluid and the first separation of Sm in the case of the following report. Materials and methods First, the isolation and identification of pathogens: Two cases of pleural effusion or bile specimens directly inoculated in broth tube enrichment culture until the broth tube turbidity, transplanted blood plate, the blood plate by 37 After culturing for 24 hours at 0 ℃, the colonies showed red color
