spp., formerly ., are gram-negative, non-motile, traditionally opportunistic pathogens that are infrequent clinical isolates. spp. have been pathogenically implicated in only 52 reported cases since the discovery of the genus in the 1920s. We present a case of spp. lower extremity cellulitis and bacteremia. To our knowledge, this is the 16th case of cutaneous infection caused by spp. Etiology of this patient's infection was felt to be related to exposure of his pre-existing lower extremity wounds to soil and water versus a dog lick in the context of relative immunosuppression from type 2 diabetes and chronic inhaled steroid use. Given the characteristic multi-drug resistance of spp., resistance to usual empiric antimicrobials given for cellulitis, and potential for fatal infection in cases of pan-resistance, it is important that clinicians remain alert to the possibility of this rare pathogen.
某菌属（以前称为某某菌属）是革兰氏阴性、无运动性的，传统上属于机会致病菌，临床分离株较少见。自20世纪20年代发现该菌属以来，某菌属仅在52例报告病例中被认为具有致病性。我们报告一例某菌属引起的下肢蜂窝织炎和菌血症病例。据我们所知，这是第16例由某菌属引起的皮肤感染病例。该患者感染的病因被认为与他原有的下肢伤口接触土壤和水有关，而非在2型糖尿病和长期吸入类固醇导致相对免疫抑制的情况下被狗舔舐所致。鉴于某菌属具有典型的多重耐药性、对蜂窝织炎常用经验性抗菌药物耐药，以及全耐药病例存在致命感染的可能性，临床医生对这种罕见病原体的可能性保持警惕很重要。
