As Keiser University students, faculty, staff and friends navigate healthcare awareness and safety issues in relation to the COVID-19 viral pandemic, Keiser University Tampa campus Biomedical Science Department Chair Dr. Clare-Anne Canfield and Instructor Dr. Neil Copes recently released this video. Designed to highlight the main differences between bacteria and viruses, the presentation reminds audiences that infections caused by viruses are extremely different than bacterial infections.

 

While demonstrating with a meter stick and an agar plate, Dr. Canfield pointed out that the human normal biota (microbes that normally live in and on us) is diverse, as there are approximately 40 trillion bacteria (measured in 1-10 micrometers) and nearly 5 times as many viruses in our intestines (measured in the 10-100 nanometer range). While bacteria can be viewed with a microscope, viruses are only visible through the use of high-powered microscopes, such as an electron microscope.  Bacteria are alive whereas viruses are not considered ‘alive’ as they lack a metabolism, which is a key feature of life. These key differences are important because medical doctors and researchers must know what they are working with before they can administer medication. The minuscule size and lack of metabolism make studying viruses much more difficult than bacteria.

 

The Keiser University Bachelor of Science Degree in Biomedical Sciences program prepares students for entry into health sciences and analytical/research laboratories. Graduates possess the skills to perform in a variety of science-related positions in health departments, zoos, clinical and environmental chemistry, pharmaceutics, and laboratories.  Graduates of the program will have completed the prerequisites necessary to be successful in graduate programs in the sciences as well as a multitude of professional programs such as occupational and physical therapy, dentistry, pharmacy, physician, and physician assistant programs. However, a Bachelor of Science degree in Biomedical Sciences can also be a terminal program for individuals who wish to work in laboratory settings and other occupations.
