Detection and colonization of Desulfovibrio desulfuricans in an 84-year-old man in Japan who had undergone endovascular aortic repair 9 years earlier. A) Gram stain of pus. D. desulfuricans MB has a gram-negative spiral rod appearance (arrow). Original magnification ×1,000. B) Colonies of D. desulfuricans MB on ABHK agar. Biochemical properties showed positive results for catalase and negative for indole and urease. In vitro susceptibility testing revealed that it had the following MICs: meropenem, <2 μg/mL; cefotaxime, <2 μg/mL; ampicillin/sulbactam, <4 μg/mL; piperacillin/tazobactam, <16 μg/mL; and clindamycin, >8 μg/mL.
