The complex (BCC) represents a group of bacteria that are gram-negative, aerobic, and non-fermenters. They are notorious for causing infections in vulnerable individuals, such as those with compromised immune systems. Examples are patients suffering from cystic fibrosis or chronic granulomatous disease. These bacteria are prevalent in diverse habitats, like soil and water. Over the last four decades, they have gained recognition as both emerging opportunistic pathogens and nosocomial threats. Managing BCC infections poses significant challenges due to their inherent resistance to numerous antibiotics, thus raising substantial concerns within clinical settings. Here, we present a case series of bacteremia, with BCC as the causative organism. The isolates showed a curious phenomenon of producing a violet pigment.
嗜麦芽窄食单胞菌复合体（BCC）是一组革兰氏阴性、需氧且不发酵的细菌。它们因在免疫系统受损等易感个体中引发感染而声名狼藉。例如患有囊性纤维化或慢性肉芽肿病的患者。这些细菌在土壤和水等多种栖息地中普遍存在。在过去的四十年里，它们已被公认为新兴的机会致病菌和医院感染威胁。由于其对多种抗生素具有固有抗性，管理BCC感染带来了重大挑战，从而在临床环境中引发了诸多担忧。在此，我们呈现一系列以BCC为致病菌的菌血症病例。分离株呈现出产生紫色色素这一奇特现象。
