The contribution of iron transporter systems encoded by feo genes to the pathogenic traits of streptococci is largely unknown, despite the fact that those systems are required for the full virulence of several gram-negative bacterial specie...
Bacteriophage induction versus vaginal homeostasis: role of H(2)O(2) in the selection of Lactobacillus defective prophages [0.03%]
细菌溶源诱导与阴道稳态：H₂O₂在乳杆菌缺陷型原噬菌体选择中的作用
Rebeca Martín,Nora Soberón,Susana Escobedo et al.
