Abstract

ochrobactrum anthropi ( O.anthropi) ,önceleri Achromobacter spp. veya CDC grup Vd olarak adlandÖrÖlmÖĹ olup, çevresel ortamlarda yaygÖn bulunur. Nadir olarak insanlarda etken olabilen gram negatif aerop nonfermenter bir mikroorganizmadÖr. Mac Conkey agarda ürer. Peritriköz flagellalarÖ ile hareketlidir. Son yÖllarda insanlarda fÖrsatçÖ nozokomiyal enfeksiyon etkenleri arasÖnda görülme sÖklÖþÖ artmÖĹtÖr. Çoþu sistemde enfeksiyona neden olmakla birlikte sÖklÖkla immünsüprese bireylerde santral venöz kateter enfeksiyonu etkeni olarak bildirilmektedir. Burada , akut miyeloid lösemi (AML) nedeni ile daha önce allojenik kök hücre nakli yapÖlmÖĹ ve sonrasÖnda nüks nedeni ile kemoterapi alan bir vakada geliĹen O.anthropi bakteriyemisi sunulmuĹtur

İmmünsüpresif Bir Hastada Gelişen Ochrobactrum Anthropi Bakteriyemisi

Abstract

O.anthropi formerly known as Achromobacter spp. or CDC group Vd, can be isolated from various environmental sources. It’s an aerobic, gram negative, nonfermentative microorganism, which can rarely cause infection in humans. It grows on Mac Conkey agar plate. It’s peritrichious flagellated and motile. Recently it has been increasingly seen as a nosocomial pathogen in humans. Mostly O.anthropi is reported as a cause of catheter related bloodstream infection, but it can cause infection in most organ systems. Here, O.anthropi bacteremia is presented in a patient who’s receiving chemotherapy for relapsed acute myeloid leukemia (AML) and previously had haematopoetic stem cell transplantation (HSCT)
