|pathogenesis of a disease is the biological mechanism (or mechanisms) that lead to the diseased state. Pathogenesis is the development of disease, from the initial appearance of disease all the way to its end stages. It is a multi-factorial process which depends on the immune status of the host, the nature of the species or strain (virulence factors) and the number of organisms in the initial exposure. The study of pathogenesis is important for medical professionals, as it helps them identify and treat diseases. It is also part of the work of laboratory sciences who work on cures and treatments for diseases, as each stage of pathogenesis represents a potential possibility for interrupting the progression of the disease.
Journal Article is sometimes called a Scientific Article, a Peer-Reviewed Article, or a Scholarly Research Article. Together, journal articles in a particular field are often referred to as The Literature.
Journal articles are most often Primary Research Articles. However, they can also be Review Articles. These types of articles have different aims and requirements. Sometimes, an article describes a new tool or method.
Because articles in scientific journals are specific, meticulously cited and peer-reviewed, journal databases are the best place to look for information on previous research on your species. Without a background in the field, journal articles may be hard to understand - however, you do not need to understand an entire article to be able to get valuable information from it.
