Creating a Bacterial Key

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
