Characteristics and spatiotemporal changes in phenotypes and genotypes of extended-spectrum β-lactamases in Escherichia coli isolated from bloodstream infections in China from 2014... by Sayyed Salman, Hao Xu, Yunbo Chen, Jinru Ji, Zhiying Liu, Yonghong Xiao

“…Regarding the geographical distribution of the ESBLs, the highest rate of ESBL genetic positivity was observed in Southwest China, accounting for 84.9% (45/53), and the lowest was observed in Northeast China, with 73.2% (30/41). The abundance of the bla CTX−M−27 genotype, in particular, exhibited a notable increase in Southwest China, with 31.4% (14/45) of the strains exhibiting this genotype, followed by the CTX-M-55 genotype, with 13.6% (6/45) of the strains exhibiting this genotype. …”

The clinical prediction model to distinguish between colonization and infection by Klebsiella pneumoniae by Xiaoyu Zhang, Xifan Zhang, Deng Zhang, Jing Xu, Jingping Zhang, Xin Zhang

“…ObjectiveTo develop a machine learning-based prediction model to assist clinicians in accurately determining whether the detection of Klebsiella pneumoniae (KP) in sputum samples indicates an infection, facilitating timely diagnosis and treatment.Research methodsA retrospective analysis was conducted on 8,318 patients with KP cultures admitted to a tertiary hospital in Northeast China from January 2019 to December 2023. After excluding duplicates, other specimen types, cases with substandard specimen quality, and mixed infections, 286 cases with sputum cultures yielding only KP were included, comprising 67 cases in the colonization group and 219 cases in the infection group. …”
