Q

Neisseria cocci

Study These Flashcards
A
  • meningitis

- capsule

25
In what age group is meningitis most common?
- college students
26
Pseudomonadales aeruginosa
- rods - flagella (mono or lopho) - aerophile - produce pigment (blue-green) - can cause UTI - grows on burn wounds - grow in quads - grow in abtibodies aniseptis - grow on foods
27
Moraxella lacunta
- coccobacillus - conjunctivitis - gamma - pseudomonodales
28
Legionella pneumophile
- rod - spread by water - causes pneumonia (mild or fatal) - gamma
29
Coxiella burnetti
- rod - spreads through endospores - causes pneumonia - legionellales - gamma
30
Vibrionales
- move with flagella - cause cholera - facultative anaerobe - gamma
31
Enteriobacteriales all...
- rods - facultative anaerobes - flagella (peri-trichous) - attach to intestine using fimbrae - use pilus - produce bacteriocins
32
Escherichia coli
- "coliform" - gastroenteritis - traveller's diarrhea - UTI - grows well in lab - Gamma
33
Salmonella
- gastroenteritis - found in food - gamma - enteriobacteriales
34
What is the difference between S. enterica and S. hyphi?
S. e- from food | S. h- human carrier
35
Shingella
- dysentry - 10-20 bowel movements - severe dehydration - gamma - enteriobacteriales
36
Hemophilus influenza
- pasteuralles - gamma - not related to flu - loves blood (grown in blood agar) - require X-factor needed for aerobic resp, and ETC cytochrome and V-factor (NAD) - cause meningitis, otitus medi, pneumonia, arthritis, and epiglottis
37
Helicoptor pylori
- peptic ulcer - epsilon - microaerophiles - peri-trocher - vibrio
38
Compylobacter jejuni
- gastroenteritis - microaerophiles - monotrichous - vibrio - epsilon
39
Chlamydia tranchomatis
- trachoma - lympho granuloma - non- gonnoccal urethritis - coccobacillus
40
Life Cycle of Chlamydia tranchomatis
1. Elementary Body 2. Reticulate Body 3. New Elementary Body created * only stopped with antibiotics
41
Fusobacteria/ Bacteriodes
- rods - anaerobe - oral cavity (gingivitis)
42
What is the difference between Fusobacteria/ Bacteriodes?
pertionitis present in bac not fus
43
Spirochetes
- treponema pallidum - spiral - hair-like - cannot grow in lab with live organism (wiggle away) - often use rabbits for testing as they have the same symptoms as us
44
Clostridales
- form endospores - terminal - rods anaerobe - carried in soil
45
Bacillus anthracis
- endospores - central - rods - aerobic or facultative anaerobes - soil - bioweapon
46
Staphylococcus aureus
- bacillus - cluster - cocci - facultative anaerobe - skin infecton - TSS - food poisons - UTI - skin flora
47
Lactobacillus
- obligate fermentors - in commercial items (cheese/yogurt) - aerotolerant - rods
48
Lactobacillus in Hospitals
- keeps genital region sterile - increase in quantity in puberty and pregnancy - disturbance causes UTI (e.g strong soaps) - acidic - newborn's first contact
49
Streptococcus
- Aerotolerant | - requires blood agar
50
What is Alpha-Hemolysis?
- green zone - Hb changes into Meth Hb (causes green colour) - S mutans, S pneumonia
51
What is Beta-Hemolysis?
- clear zone | - Rheumatic fever and Scarlet fever grow like this
52
What strain of Streptococcus does not require blood agar?
S. Mutans
53
Listeria monocytogenes
- lactobacille - grow in monocytes - rods - facultative anaerobe - psychotrophs - milk, feta, salads, brie, sausage, cold cuts
54
Mycoplasma
- no cell wall - very contagious with mild symptoms - fried egg - pleomorphine - add sterols (steroid alcohol in membrane allows for membrane fluidity regulation) - pliable
55
Why is penicillin useless for Mycoplasma? What is used instead?
- no cell wall | - tetracycline
56
Myobacterium tuberculosin
- rods - aerobic - mycholic acid in waxy lipid layer - acid fast staining - nutrients enter slowly - resistant to dying (spread through body fluids) - resistant to antibiotics - resistant to antiseptics - colonies appear in 4-6 months
57
Cornybacterium Diotheriae
- rod arranged in picket fence or pleomorphic arrangement - facultative anaerobe - diptheria suffocates - quickly developing - prevented with DTaP - metachromatic granules - store phosphate
58
Propionibacterium acnes
- rods - anaerobic - sebum in acne - P. species ferments swiss cheese creating flavour and holes
