Q

outermost layer which gives shape & integrity to bacteria; its makeup used to differ among m.o.’s; e.g, high lipid for TB; protein in Gram stain (blue if yes, red if no-named for Robert Gram tested use)

23
Q

thinner, inner layer; controls entry & exit into bacteria

A

Cell membrane:

24
Q

living substance in cell

A

Cytoplasm:

25
Q

located on outside of certain bacteria; protects cell from phagocytosis, thus enhancing “virulence” of m.o.

A

Capsule (slime layer):

26
Q

best means of protection any m.o. can possess; NOT a means of reproduction; only 1 per cell when formed; Bacillus & Clostridium only

A

Endospore:

27
Q

any bacteria that can never form endospores (does not have genus name Bacillus or Clostridium), or can produce endospores but currently not producing them

A

Vegetative bacteria:

28
Q

any bacteria currently producing endospores; occurs under adverse living conditions (change in temp/ph, medication given)

A

Sporulating bacteria:

28
Q

used for movement of bacteria; long, whiplike structures attached to outside; many variations (e.g. monotrichous, peritrichous)

A

Flagella:

29
Q

when free endospore forms new vegetative cell when good living conditions return

A

Germinating bacteria:

30
Q

“little hairs”; shorter than flagella and used to aid in attachment to the initial site of infection; e.g. gonorrhea

A

Pili:

31
Q

Bacterial typical reproduction binary fission (simple transverse division); an asexual means

A

1

32
Q

obtain their food from inorganic matter; manufacture its on carbon

A

Autotrophic bacteria:

33
Q

Conditions Affecting Bacteria Growth

A
  1. Food requirements
  2. Oxygen requirements
  3. Moisture (water) requirements
  4. pH
34
Q

obtain food from organic matter; all pathogens are so classified

A

Heterotrophic bacteria:

35
Q

any organism that must obtain food from dead organic matter

A

Strict (obligate) saprophytes:

36
Q

organism that must obtain food from living organic matter

A

Strict (obligate) parasites:

37
Q

organisms that lives in present of oxygen but at a level required less for humans

A

Microaerophiles:

38
Q

organisms that can live in either the present or absence of oxygen

A

Facultative bacteria:

40
Q

percentage of H ion in solution; slightly alkaline for most pathogens

A

pH:

41
Q

pH scale range from 0 (most acidic/sour taste) to 14 (most alkaline)

When tested Acidic shows red and Alkaline shows blue

A

range 0-7 acidic closer to 0 is darker red color

range 7-14 alkaline closer to 14 is darker blue color

42
Q

neutral (water)

A

7

43
Q

slightly alkaline (human body & blood)

A

7.3 - 7.4

44
Q

moderately alkaline / alkaline basic (bitter taste)

A

10.5

45
Q

highly alkaline (milk)

A

13

46
Q

slightly acidic (pick up stiff body of rigamorrtis - but as embalming body it becomes more alkaline)

A

48
Q

  • cause meningitidis
A

A

Salmonella typhi

54
Q

( Hemophilus= blood loving bacteria) caused influenza, influenza meningitidis

A

Hemophilus influenzae

55
