A conventional PCR and a real-time PCR for detecting Bacteroides fragilis were evaluated against clinical specimens. Analytical sensitivities were 100 and 40 fg of DNA, respectively. Detection limits were 100 and 10 CFU/ml, respectively.

We describe two cases of infections due to isolates simultaneously resistant to clindamycin, tetracycline, cefoxitin, piperacillin-tazobactam, and imipenem and, in one of the two cases, to metronidazole. Such infections, although still rare, do exist and tend to complicate treatment.

Following a kidney transplantation operation and an acute rejection of the transplant, an aneurysm developed at the site of the arterial ligation and three stents were inserted. Two months following insertion of the stents, recurrent episodes of peripheral thromboembolism occurred.
