Infectious Bacteria, Viruses, and Eukaryotes

Paper Summary:

This paper discusses the threats of infectious organisms, with a focus on their ports of entry. The paper explains that typical portals of entry include the mouth, ears, eyes, urethra, nose, and skin, while non-typical portals might include wounds, broken skin, insect bites, or even animal bites or stings. The paper explores the E. coli bacteria, Hepatitis A ,and Guardia Lamblia, providing explanations of how these diseases may be contracted and various methods for treatment and prevention.

From the Paper:

"Indeed, the specialized preferences of many organisms with regard to ports of entry are so consistent that it is often taken as a hallmark of a particular organism in the diagnosis phase. This is especially important when one notes that the symptoms of characteristic of a specific infection usually give clear clues as to the point of entry. Although it is important to consider the point of entry when diagnosing the cause of illness in a patient, it can also be important for many aspects of disease prevention, especially when a high risk for a particular organism is present in one's environment. For example, if one knows that he or she is working in an environment where there is a high incidence of an airborne pathogen, steps can be taken (the wearing of masks the use of patient isolation procedures for example) to minimize possible exposures to that pathogen."
