Flashcards in Bacteria Deck (94)
Loading flashcards...
1
prokaryotic, cell wall, single chromosome, 70S ribsome
bacteria characteristics
2
stain, shape, oxygen requirements, temperature, others
classification of bacteria
3
lag, log, stationary and death
bacterial growth phases
4
number of cells are constant as they prepare for growth; no multiplication
lag growth phase
5
exponential growth
log growth phase
6
new growth matches die off rate as nutrients run out of food
stationary growth phase
7
gram positive (BLUE) or negative (RED)
stain
8
crystal violet, H2O, iodine, H2O, acetone alcohol wash, safranin, H2O
gram stain
9
iodine (mordant or fixer) and safranin (counterstain)
mordant and counterstain
10
coccus (round), bacillus (rod) or vibrio (comma-shaped)
shape
11
aerobic (grows in O2) or anaerobic (can grow without O2)
oxygen requirement
12
prefers to live without O2 but has the facility (ability) to live with oxygen
facultative anaerobic
13
cannot live in the presence of O2
obligate anaerobic
14
cannot live without oxygen-mycobacteria, bacillus, and pseudomonas
obligate aerobic
15
needs a very small amount of O2 - helicobacter pylori, treponema pallidum
microaerophilic
16
thermophile (45-900), mesophile (20-450), or psychrophile (0-200)
temperature preferences
17
urease, nitrite producing, catalase positive, specific sugar fermentation
other ways of grouping bacteria
18
klebsiella, proteus, ureaplasma, nocardia, (cryptococcus), helicobacter
urease (urea splitting)
19
klebsiella, escherichia coli, enterobacter, pseudomonas, proteus, serratia
nitrite-producing
20
pseudomonas, listeria, escherichia coli, and staphylococcus
catalase - positive
21
staphylococcus aureus; all other staphylococci and coagulase negative
coagulase - positive coccus
22
neisseria gonorrhea and neisseria meningitidis
glucose - fermentation coccus
23
escherichia coli and klebsiella pneumoniae
lactose - fermenting bacilli
24
neisseria meningitdis and proteus mirabilis
maltose fermenting bacteria
25
mycoplasma
bacteria without cell walls
26
chlamydia, rickettsiae, ehrlichia, bartonella, and coxiella
obligate intracellular parasite
27
borrelia, leptospira, treponema
flexible bacteria (spirochetes)
28
all bacteria have cell walls except MYCOPLASMA
bacteria rule 1
29
all cocci are gram + except NEISSERIA
bacteria rule 2
