Abstract

Acinetobacter baumannii is a gram-negative nonfermentative bacteria that cause hospital-acquired bacteremia, pneumonia, meningitis and urinary tract infections, especially in intensive care units. The pigmented strains of Acinetobacter bacteria can be found in environmental specimens but are rarely isolated in clinical specimens as an etiologic agent of infection. A 66-year-old male patient was admitted to Urology Department of Dokuz Eylül University Medical Faculty Hospital, with the initila diagnosis of Fournier gangrene. We observed that A. baumannii isolated from three specimens obtained by partial penectomy, urethrectomy and wound site debridement, produced a brown pigment that spread on Mueller Hinton agar. Identification was done with conventional methods and with two different automated identification systems. The biochemical characteristics of the brown pigment produced by A. baumannii strain could not be characterized. We think that the contribution of this brown pigment to A. baumannii pathogenicity should be investigated which is rarely found in clinical isolates.

Özet

Acinetobacter baumannii özellikle yoğun bakımünitelerinde yatan hastalarda hastane kaynaklı bakteriyemi,pnömoni, menenjit ve idrar yolları enfeksiyonlarına nedenolan Gram negatif nonfermentatif bir bakteridir.Acinetobacter cinsi bakterilerin pigmente suşlarına çevreselörneklerde rastlanabilmekte, ancak klinik örneklerdeenfeksiyon etkeni olarak ender olarak izole edilmektedir.Dokuz Eylül Üniversitesi Tıp Fakültesi Hastanesi ÜrolojiServisi’ne fournier gangreni ön tanısı ile yatırılan 66yaşındaki erkek hastanın parsiyel penektomi, üretrektomi,yara yeri debridmanı ile alınan üç örneğinden izole edilenA. baumannii izolatının Mueller Hinton agarda yayılabilenkahverengi pigment ürettiği gözlemlendi. Tanımlamakonvansiyonel yöntemlerle birlikte iki ayrı otomatizetanımlama sistemleri ile yapıldı. A. baumannii suşununürettiği kahverengi pigmentin biyokimyasal özelliklerikarakterize edilmedi. Klinik izolatlarda ender olaraksaptanan bu kahverengi pigmentin A. baumanniipatojenitesine katkısının araştırılması gerektiğinidüşünmekteyiz.
