is one of the most clinically relevant species in immunocompromised individuals responsible for community-acquired and nosocomial infections, including pneumonias, urinary tract infections, bacteremias, and liver abscesses. Since the mid-1980s, hypervirulent , generally associated with the hypermucoviscosity phenotype, has emerged as a clinically significant pathogen responsible for serious disseminated infections, such as pyogenic liver abscesses, osteomyelitis, and endophthalmitis, in a generally younger and healthier population. Hypervirulent infections were primarily found in East Asia and now are increasingly being reported worldwide. Although most hypervirulent isolates are antibiotic-susceptible, some isolates with combined virulence and resistance, such as the carbapenem-resistant hypervirulent isolates, are increasingly being detected. The combination of multidrug resistance and enhanced virulence has the potential to cause the next clinical crisis. To better understand the basic biology of hypervirulent , this review will provide a summarization and discussion focused on epidemiology, hypervirulence-associated factors, and antibiotic resistance mechanisms of such hypervirulent strains. Epidemiological analysis of recent clinical isolates in China warns the global dissemination of hypervirulent strains with extensive antibiotic resistance in the near future. Therefore, an immediate response to recognize the global dissemination of this hypervirulent strain with resistance determinants is an urgent priority.
是免疫功能低下个体中最具临床相关性的物种之一,可导致社区获得性和医院获得性感染,包括肺炎、尿路感染、菌血症和肝脓肿。自 20 世纪 80 年代中期以来,高毒力 ,通常与高黏液性表型相关联,已成为一种具有临床意义的病原体,可导致化脓性肝脓肿、骨髓炎和眼内炎等严重播散性感染,其患者通常更年轻、更健康。高毒力 感染主要发生在东亚,现在全球范围内的报告越来越多。尽管大多数高毒力 分离株对抗生素敏感,但一些具有毒力和耐药性的分离株,如耐碳青霉烯类高毒力 分离株,越来越多地被检测到。多药耐药性和增强的毒力的结合有可能引发下一次临床危机。为了更好地了解高毒力 的基础生物学特性,本文将重点综述和讨论此类高毒力 菌株的流行病学、与毒力相关的因素和抗生素耐药机制。对中国近期临床分离株的流行病学分析警告称,在不久的将来,高毒力 菌株将在全球范围内广泛传播,并具有广泛的抗生素耐药性。因此,立即采取措施认识到这种具有耐药决定因素的高毒力 菌株的全球传播是当务之急。
