Develop a key based on differential staining and culturing | Homework Helpers

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
