We have learned terms like 'sterile,' 'commensal,' 'contaminants,' 'germs,' 'microorganisms,' and 'infection' over the last week and in the lab. Why is it important for a health care personnel to clean the surface of a patient's skin before drawing a blood sample? Why is it important for a health care personnel to change his gloves and sanitize his hands between patients?

Which percentage of medical waste is infectious or hazardous? A) 25% B)50% C)75% D) 85%

Give a disease-causing pathogen or microbe and answer the following questions. 1. What is the name of the pathogen causing the disease? 2. What disease does the pathogen cause? 3. How is disease transmitted? 4. What are the symptoms of the disease? 5. How long does it last for? 6. Can the disease be treated? 7. Is there a vaccine for the disease?

Our environment contains masses of microorganisms, many of which reside as commensal organisms on our body’s mucosal and epithelial surfaces without causing disease. What two features distinguish a pathogenic microbe from these commensal microbes?

Rea performed a quality control on hematology section. She noticed that results were out of range for the normal control. The tests were repeated twice and produced same result. What must be the most probable reason for this scenario? How should she address this problem?

True or False: Confirmatory identification is the final identification of a bacterium.

I need help answering this question to my professor:   The topic for the discussion was this one:   Some potentially pathogenic bacteria and fungi, including strains of Enterococcus, Staphylococcus, Candida, and Aspergillus, can survive for one to three months on a variety of materials found in hospitals, including scrub suits, lab coats, plastic aprons, and computer keyboards. What can hospital personnel do to reduce the spread of these pathogens?   My answer was this one:   To reduce the spread of these pathogens an infection control protocol should be followed. Some ways in which this could be reduced is by using desinfectants, sterilization, hand washing, and disposing techniques. In addition, I currently work as a dental assistant at Jackson Main and the protocol we use is hand washing our hands for at least 20 seconds before and after seeing every patient. We use CaviWipes to disinfect every surface and autoclave every single instrument after every use. Also, we make sure to…
