1
Disease
Failure of the body to function normally.
2
Pathogens
Disease producing microorganisms.
3
Infection
Invasion of a body by a pathogen.
4
Normal Flora
•bacteria high usually lives in the body & stays within a specific population.
5
Bacilli
Rod shaped cells
6
Cocci
Round cells
7
Diplococci
Double cells
8
Streptococci
Chain cells
9
Staphylococci
Bunch of grapes
10
Curved rods
Have a slight curvature
11
Spirillum
Corkscrew like
12
Spirochetes
Wavy shaped
13
Rickettsia/chlamydia
-Only live inside cell.
-Smaller.
-Considered parasites.
14
Viruses
-tiny compared to bacteria
-contain nucleic acid(rna/DNA) but lack ability to perform protein synthesis.
-can only reproduce within living cells.
-not usually susceptible to antibiotics.
15
Fungi
-plant like
-much larger than bacteria
-grow in dark,damp places
-single cell fungi=Yeasts
-fuzzy,filamentous forms mold
-mycotic infections
(Ex. Ringworm , athletes foot, thrush)
16
Protozoa
-larger than bacteria
-one cell organisms
-found in soil & water
-(4)main divisions
•amebas
•ciliates
•flagellates
•sporozoa
17
Parasitic worms
-Helminths
-intestinal round worms
-pinworms
-hookworms
-other round worms
18
Arthropods
-mites & lice = ectoparasites
- mosquitos , fleas, ticks act as vectors
-fomites= nonliving vectors
-humans end up as host
19
Looking at Bacteria
- single cell
- cell wall
-form spores
- grouped by shapes
20
Single celled organisms
- viruses consists of DNA or RNA w/protein shell
-viruses only reproduce with a host
- fungi cost mycotic infection
-Protozoa are single celled animal like microbes
