Study led by NTU Singapore finds that microbes work as a network in causing lung infection
Traditionally, an infection is thought to happen when microbes – bacteria, fungi, or viruses – enter and multiply in the body, and its severity is associated with how prevalent the microbes are in the body. Now, an international research team…
