microbiology

 

Throughout the previous modules you have gained information on the methods used to distinguish different bacteria from one another. This activity serves to reinforce the concepts associated with biochemical tests, help you learn the metabolic strategies associated with individual or groups of bacteria, and strengthen your understanding of basic morphological differences. For this assignment, you are to choose one (1) of the groups, either A) oral/respiratory tract pathogens and commensals, or B) urogenital pathogens and commensals or C) gastrointestinal tract pathogens and commensals, and develop a key based on differential staining and culturing, morphology and the suite of biochemical tests available to identify bacteria.

 

A) Typical oral/respiratory tract pathogens and commensals –

Streptococcus pneumonia	Yersina pestis
Haemophilus influenza	Streptococcus viridans
Staphylococcus aureus	Bacillus antracis
Klebsiella pneumonia	Bordetella pertussis
Streptococcus pyogenes	Chlamydia pneumonia
Psuedomonas aeruginosa	Mycobacterium tuberculosis
Mycoplasma pneumoniae

 

B) Typical urogenital pathogens and commensals

Neisseria gonorrhoeae	Streoticiccus agalactiae
Staphylococcus saprophyticus	Clostridium perfringens
S. pyogenes	Haemophilus vaginalis
Ureaplasma urealyticum	Treponema pallidum
Chlamydia trachomatis	Serratia marcescens
Trichomonas vaginalis

 

C) Typical gastrointestinal pathogens and commensals –

Campylobaacter jejuni	Enterobacter faecalis
Salmonella typhimurin	Shigella sonnei
Escherichia coli	Bacillus cereus
Clostridium perfringens	Vibrio cholerae
C. dificile	Helicobacter pylori
Alcaligenes faecalis	Listeria monocytogenes
