BI 234 Microbiology


Lecture Hours: 3
Lab Hours: 3
Credits: 4

Presents a survey of bacteria and other microorganisms, emphasizing their impact upon human health. Includes discussion of infection, immunity, common pathogens, and mechanisms of control.

Prerequisite: Placement into WR 115  (or higher), or completion of WR 090  (or higher); and completion of BI 231  within the last seven years; or consent of instructor. (All prerequisite courses must be completed with a grade of C or better.)
Student Learning Outcomes:
  1. Describe the characteristics of microorganisms and explain their contributions to the world. 
  2. Describe how microbes are named and classified and explain the importance of these concepts to laboratory identification and microbial control. 
  3. Differentiate the major characteristics of pathogenic organisms including viruses, bacteria, protozoans, fungi, helminthes. 
  4. Describe and explain the major features of bacterial structure, morphology, metabolism, growth and genetics and relate these to disease, identification, treatment and control. I
  5. Describe the major features of selected microbial diseases including; identification of the causative agent, life cycle, transmission, symptoms, treatment and prevention. 
  6. Apply the major principles, techniques and agents (chemical and physical) of microbial control to clinical case studies. 
  7. Perform and use laboratory techniques designed to isolate, grow, maintain, and identify microbes under controlled situations including; microscopy, aseptic technique, culture techniques and microbial control. 
  8. Define and apply basic principles related to infection and disease, including; modes of invasion and establishment, factors affecting pathogenicity and development of disease, and reactions of the human body to invasion and tissue damage. 
  9. Describe the development of immunity, the nature of vaccines and immunization. 

 

Statewide General Education Outcomes:

Upon successful completion of the Science course, students should be able to:

  1. Gather, comprehend, and communicate scientific and technical information in order to explore ideas, models, and solutions and generate further questions.
  2. Apply scientific and technical modes of inquiry, individually, and collaboratively, to critically evaluate existing or alternative explanations, solve problems, and make evidence-based decisions in an ethical manner.
  3. Assess the strengths and weaknesses of scientific studies and critically examine the influence of scientific and technical knowledge on human society and the environment.
