在前期發光桿菌(Photorhabdus)eCIS系統研究工作的基礎上【6】, 2019年10月8日,首都醫科大學附屬北京友誼醫院楊國威團隊、中國醫學科學院病原生物學研究所楊劍團隊與英國華威大學Waterfield團隊合作在Cell Reports雜志發表題為Genome-wide identification and characterization of a superfamily of bacterial extracellular contractile injection systems的研究論文,通過對公共數據庫中細菌基因組大數據的生物信息學分析,系統闡釋了eCIS在細菌中的分布狀況及亞型分化,并構建了專門的eCIS數據庫dbeCIS ,為進一步深入開展不同細菌中的eCIS功能研究奠定了重要數據基礎。
