Medical Microbiology

At the end of this, course the students should be able to: 1. identify microorganisms associated with disease processes and the need for infection control measures in radiography procedures; and 2. identify common vectors of pyrogens in the equipment and accessories use for radiographic examinations.

Introduction to Medical Microbiology. Basic concepts and terminologies. infection and disease pathogenicity and virulence, immunity, hypersensitivity, latency and communicability. Pathogenic properties of bacteria: invasiveness, toxigenicity and exotoxins, virulence properties. Host defense mechanisms: skin and mucous membrane barriers, phagocytic defense and inflammation, bacterial infection. The pathogenicity, morphology and cultural characteristics of certain groups of bacteria. Gram-positive bacteria – bacillus, clostridium, staphylococcus and streptococcus; gram-negative bacteria – the family enter bacteria, Neisseria, pseudomonas and vibrio; mycotic infection, types of mycoses. The morphology, laboratory diagnosis and treatment of disease caused by certain groups of fungi to include aspergillus, blastomyces, candida, cryptocossus, histoplasma, sporotrichum and yeasts; viral infections: classification of viruses, distinctive properties of viruses, method for the diagnosis of viral infections. 300 Level
