Course description:
Topics of this course cover the fundamentals of organisms causing
infections to humans for undergraduate pharmaceutical students. This
course includes three major topics "bacteriology, mycology and
virology". Medical bacteriology covered the important micro-organism
causing disease. Each micro-organism is studied from the following
topics: Morphology and characters, virulence factors "surface antigen,
toxins and enzymes", pathogenesis, the disease caused by infectious
micro-organism, clinical and laboratory diagnosis, prophylaxis,
epidemiology, vaccination and treatment. Medical mycology involved
introduction and classification of fungi. In addition, study of medically
important fungi that caused human disease. Medical virology was
previously studied under PHT226.
Prerequisite:
PHT226
Credits:
Three credits distributed as 2+1 (Lectures + Laboratory)
Course Proficiencies:
The students at the end of the course must be able to:
1- Define of causative agents causing human diseases
2- Define Role of virulence factors to established the diseases
3- Describe the of mode of transmission of the infectious diseases,
incubation period of pathogenic micro-organisms, and signs and
symptoms of the disease
4- Define the basis of diagnosis of micro-organism-causing infection
5- Describe the fundamentals of epidemiology of diseases, in addition
their prophylaxis, prevention and control, vaccination and
treatment of infectious diseases

Lab description
1
Staphylococci
Use of catalase test to differentiate between staphylococci and
streptococci. Laboratory diagnosis of staphylococci by gram stain and
biochemical tests as coagulase, DNase, Mannitol fermentation on
Mannitol salt agar and novobiocin sensitivity tests to differentiate
between S. aureus, S. epidermidis and S. saprophyticus using
2
Streptococci
Use of blood agar to differentiate between , ,  haemolytic
streptococci. Use of bacitracin to identify Strepococcus pyogenes. Use
of CAMP test to identify Streptococcus agalactiae. Use of optochin
and bile soloubility tests to differentiate between viridans streptococci
and Streptococcus pneumoniae.
3
Corynebacterium
Use of Gram stain to characterize the morphology of
Corynebacterium. Use of Loefflers serum agar medium as growing
medium for corynebacteria. Elek's test and sucrose fermentation to
differentiate between Corynebacterium diphtheriae and diphtherioids.
4
Bacillus
Gram stains to characterize Gram-positive bacilli. Spore staining to
characterize the spores of Bacillus. Motility test and hemolysis on
blood agar to dipherntiate between Bacillus anthracis and Bacillus
cereus
