Bacteria!! All you Microbiologists out there, please help!?

Any information you know for sure would be greatly appreciated. Below is a list of bacteria. If you can answer any of the questions about the bacteria, (farther below) that would help, or maybe a website that will help me? Please label the bacteria and questions you answer. Thanks for your help!





Bacteria:


Shigella Dystenteriae


Clostridium Tetani


Klebsiella pneumoniae


Streptococcus pneumoniae


Treponema Pallidum (syphillis)


Pseudomonas Aeruginosa


Borrellia burgdorferi


Sprillum voltans


Clostridium Perfingens








Questions to answer about each:





1) What is the species reaction to Gram's staining method?


2) Is the species pathogenic?


3) Symtoms?


4) Treatment?


5) Mode of transportation ( ex. fecal contamination of food/water)


6) Does it make endospores


7) When grown on an agar plate, what is the colony shape/color


8) Does it produce an enzyme/toxin?

clostridium test gave 1,920,000 links. The first link I gave you is a general one, and the second is specific to (some) clostridia. The third link refers to shigella.





I answered only what I could, partly with the help of the article accessed by the links I gave.








1) What is the species reaction to Gram's staining method? Clostridia =%26gt; Gram positive, shigella =%26gt; Gram negative


2) Is the species pathogenic? Shigella, Clostridium, Klebsiella, Streptococcus, Treponema


3) Symptoms? Shigella: dysentery e.g. vomiting and / or diarrhea. Clostriidium tetani (lockjaw) ?Clostridium perfringens gangrene (in limbs), gas production, they thrive in the absence of oxygen, 2 pneumoniae lung infection, syphilis - brain infection and more.


4) Treatment? Shigella - probably rehydration therapy e.g. drinking a mixture of glucose and some simple salts (better than water) OR put on an intravenous drip, providing this. Unlike the article, I suggest treatments for gangrene: e.g. 1) Washing and cleaning a wound, vigorously if necessary. 2) Antibiotics 3) hyperbaric oxygen i.e. oxygen under pressure, which might leak into the wound. 4) Surgically opening a wound and letting oxygen in!


5) Mode of transportation? Shigella probably water-borne fecal contamination) tetanus probably food, syphilis sexual intercourse, Clostridium perfringens could probably occur from a contaminated stab wound which might if untreated become anaerobic., tetanus: spores getting into a wound


6) Does it make endospores? Clostridia [Yes, spores], shigella [No spores]


7) When grown on an agar plate, what is the colony shape/color.


8) Does it produce an enzyme/toxin? Clostridia
