In recent years, Klebsiella pneumoniae (Kpn) has evolved into a global public health threat. Convergent Kpn lineages that are both hypervirulent and multidrug-resistant have emerged and can cause community-acquired, drug-resistant infection...
A genome-wide screen in Pseudomonas aeruginosa identifies genes impacting production of the hemolytic phospholipase C/sphingomyelinase, PlcH [0.03%]
全基因组筛选鉴定出影响恶臭假单胞菌血红素磷脂酶C/鞘氨醇磷酸-diesterase(PlcH)产生的基因
Kristin Schutz,Olivia F Evans,Jacob R Mackinder et al.
Kristin Schutz et al.
The secreted phospholipase C/sphingomyelinase, PlcH, is the heat-labile hemolysin of Pseudomonas aeruginosa and one of its important secreted virulence factors. While there are known and suspected genes that impact PlcH production in P. aer...
Transcriptional landscape of metal-resistant Cupriavidus metallidurans: one sigma factor to rule them all [0.03%]
金属耐受型芽孢杆菌的转录图谱:一个σ因子统治他们所有
Dietrich H Nies,Jan Grau,Grit Schleuder et al.
Dietrich H Nies et al.
Cupriavidus metallidurans is able to grow in the presence of transition metal mixtures with high concentrations and varying compositions. This ability is mediated by a multitude of metal transport and repository systems. To reveal the genet...
