We report a catalase-negative Staphylococcus aureus isolated from a 56-year-old male diabetic patient with foot ulcer who attended our surgery ward. Species identification was confirmed by Gram staining, standard biochemical tests and PCR amplification of the nuc and fem genes. Antibiotic susceptibility showed that the strain was sensitive to imepenem, chloramphenicol, amoxicillin, vancomycin and resistant to oxacillin, penicillin, ceftriaxone, erythromycin, clindamycin, and amikacin. Clinicians and microbiologists must be encouraged to identify and report these atypical strains and the infections associated with them in order to establish their role in pathogenesis.
我们报告了从一名56岁患有足部溃疡的男性糖尿病患者身上分离出的一株过氧化氢酶阴性金黄色葡萄球菌，该患者曾入住我们的外科病房。通过革兰氏染色、标准生化试验以及nuc和fem基因的PCR扩增确认了菌种鉴定。药敏试验表明该菌株对亚胺培南、氯霉素、阿莫西林、万古霉素敏感，对苯唑西林、青霉素、头孢曲松、红霉素、克林霉素和阿米卡星耐药。必须鼓励临床医生和微生物学家识别并报告这些非典型菌株及其相关感染，以便确定它们在发病机制中的作用。
