The objectives of the two types of research and their underlying philosophical assumptions are simply different. However, as discussed in the section on âphilosophies guiding researchâ, this does not mean that the two approaches cannot be used in the same study.
Signs and symptoms. Contagious impetigo. This most common form of impetigo, also called nonbullous impetigo, most often begins as a red sore near the nose or mouth which soon breaks, leaking pus or fluid, and forms a honey-colored scab, followed by a red mark which heals without leaving a scar.
What causes impetigo? Impetigo is caused by one of two kinds of bacteria-strep (streptococcus) or staph (staphylococcus). Often these bacteria enter the body when the skin has already been irritated or injured because of other skin problems such as eczema, poison ivy, insect bites, burns, or cuts.
