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

21

Multicellular organisms

-worms (round or flat)
•transmission by fecal-oral route
-Arthropods
•animals with jointed legs
•ectoparasites &vectors
