(2) 5. Placement: Second year / First semester 6. Instructors: Staff of microbiology Unit. 7. Course Description: his course is designed to provide the nursing student with basic theoretical and practical knowledge in microbiology. Therefore, he would be aware of the activities of microbial world in the clinical areas and his daily living, and acquires a scientific approach to control infection. 8. Course Goals: At the end of the course the student will be able to: Review the historical development of microbiology. Recognize types of microorganisms that cause infectious diseases. Interpret diagnostic methods and laboratory findings to make the ultimate diagnosis. Describe types of parasites, their structures, figures, hosts, lifecycle, pathogenic effects, methods of diagnostic and treatment. Understand principles and methods of sterilization relative to nursing care. Use the microscope efficiently Demonstrate slide preparation processes.

2 The principles of chemotherapy through the use of appropriate antimicrobial agents and laboratory techniques Collect clinical specimens and disposal of contaminated materials. Elaborate kinds of body defense against infection. Discuss types of body immunity. 9. Course Outline: The Theoretical Content Unit 1: Introducon and the historical development of microbiology.
