Bio Ch 10 Disease Biology Practice Flashcards
explain what it means if someone is said to be suffering from an “acute rhinovirus infection.”
The common cold can be spread through droplets of a pathogen colonizing (organism present) and last a short time.
Briefly explain what you are saying differently from (a.) if you say someone is suffering from “acute rhinovirus disease.”
The common cold can be spread through droplets of impairment of function (symptoms present) ENDS WITH RETURN OF NORMAL FUNCTION
Briefly explain what it means if someone is said to be suffering from a “chronic infection causing initial acute disease.”
A long-time infection that caused the initial short disease is so infectious with the disease.
Briefly explain what it means if someone is said to be suffering from an “acute infection causing chronic disease.”
A short-term infection caused a chronic disease that is long-term that affects the rest of your life maybe years.
Correctly use the disease biology terms from the course to describe the typical pattern of how Varicella zoster interacts with the people it enters
Varicella zoster (chicken pox) is highly contagious by a direct transition in which the person is an acute disease in which the person is infected, disease, and infectious.
Briefly explain how what it means to say that “SARS-CoV2 usually is passed directly, but under certain situations is transmitted indirectly via airborne or vehicle transmission.
enveloped RNA virus entered via droplets usually which is a vehicle transmission. which results in it ending with infected and infectious which could be a chronic illness.
Using ecological principles briefly explain why it is not surprising that dry skin has higher microbial species richness than moist or oily skin.
skin is the human body’s largest organ, colonized by a diverse milieu of microorganisms, most of which are harmless or even beneficial to their host
Explain what a biofilm is and how the ecological process of succession is related to dealing with the most common oral-cavity biofilms.
an assemblage of surface-associated microbial cells that is enclosed in an extracellular polymeric substance matrix but they form the basis of food webs and ensure nutrient cycling and bioremediation in natural systems.
Explain why and how Clostridium difficile causes disease.
difficile can cause the colon to become inflamed and sometimes form patches of raw tissue that can bleed or produce pus. Signs and symptoms of a severe infection include Watery diarrhea as often as 10 to 15 times a day. Abdominal cramping and pain may be severe.
Briefly explain what should be done to address the increasing problems with C. difficile in hospitals.
Wear gloves and a gown when entering CDI patient rooms and during their care. As no single method of hand hygiene will eliminate all C. diff spores, using gloves to prevent hand contamination remains the cornerstone for preventing C. diff transmission via the hands of healthcare person
