Copper selects for siderophore-mediated virulence in Pseudomonas aeruginosa: data

Data for the paper entitled 'Copper selects for siderophore-mediated virulence in Pseudomonas aeruginosa'. Columns are: - copper: 1 = no copper control, 2 = 0.1g/L copper sulphate, 3 = 1.0g/L copper sulphate. - rep: rep identifier to allow control of repeated sampling - death: the number of larvae dead out of 20 - pyo: the amount of pyoverdine in the sample. Values of sterile media are already subtracted from these readings. - od: the optical density of each sample. Values of sterile media are already subtracted from these readings. - tp: timepoint. 1 = 2 days, 2 = 12 days - cfu: the number of colony forming units per 25µL of freezer stock. This is made with 50% glycerol. - strain: wildtype = a pyoverdine and pyochelin producer, mutant = a non-producer本数据集配套于题为《铜对铜绿假单胞菌嗜铁载体介导毒力的筛选作用》的学术论文。各列字段说明如下： - copper：1代表无铜对照组，2代表0.1g/L硫酸铜处理组，3代表1.0g/L硫酸铜处理组。 - rep：重复样本标识符，用于规范重复采样的质控流程。 - death：20只受试幼虫中的死亡个体数。 - pyo：样本中绿脓杆菌素（pyoverdine）的含量，该检测值已扣除无菌培养基的背景信号。 - od：各样本的光密度值，该检测值已扣除无菌培养基的背景信号。 - tp：时间点分组，1对应培养2天，2对应培养12天。 - cfu：每25µL添加50%甘油的冻存液中的菌落形成单位（colony forming unit, CFU）数量。 - strain：菌株类型，野生型（wildtype）为可合成绿脓杆菌素（pyoverdine）与脓杆菌素（pyochelin）的菌株，突变型（mutant）为无法合成这两种物质的菌株。
