Laribacter hongkongensis is relatively a new name in the list of bacterial pathogens for gastroenteritis and travelers' diarrhea. Addition of another name increases burden on the enteric infections as a whole. L. hongkongensis belongs to Neisseriaceae family of β subclass Proteobacteria. L. hongkongensis was initially isolated in Hong Kong from blood and empyema of an alcoholic cirrhotic patient in 2001, followed by reports from Korea and China, representing a total of 38 articles in PubMed until April 2013. As of now, there is no report from Indian subcontinent where infectious diarrhea is very much prevalent and a major burden. This review provides information about the microbiological characteristics, consideration of an emerging pathogen, relative pathogenicity, genome and proteome content, resistance toward multiple antibiotics, adaptability to different stress, and other features since its time of discovery. Investigation for this bacterium may avoid misidentification as other microbial flora. Further studies like the geographical distribution, type of infection, disease burden, pathogenicity, or genomic exploration of this bacterium will be useful in characterizing them properly. This bacterium may possibly be the emerging threat to public health.
香港拉氏杆菌在引起肠胃炎和旅行者腹泻的细菌病原体名单中相对是个新名称。增添另一个名称整体上增加了肠道感染的负担。香港拉氏杆菌属于β-变形菌纲奈瑟菌科。香港拉氏杆菌最初于2001年在香港从一名酒精性肝硬化患者的血液和脓胸中分离出来，随后韩国和中国也有相关报道，截至2013年4月，在PubMed上共有38篇文章。目前，在感染性腹泻非常普遍且是主要负担的印度次大陆尚无相关报道。这篇综述提供了自其被发现以来有关该菌的微生物学特征、作为一种新兴病原体的考量、相对致病性、基因组和蛋白质组内容、对多种抗生素的耐药性、对不同应激的适应性及其他特征的信息。对这种细菌的检测可避免将其误鉴定为其他微生物菌群。像这种细菌的地理分布、感染类型、疾病负担、致病性或基因组探索等进一步研究将有助于对它们进行恰当的特征描述。这种细菌可能是对公共卫生的新兴威胁。
