  • hookworms
  • other round worms
18
Q

Arthropods

A
  • mites & lice = ectoparasites
  • mosquitos , fleas, ticks act as vectors
  • fomites= nonliving vectors
  • humans end up as host
19
Q

Looking at Bacteria

A
  • single cell
  • cell wall
  • form spores
  • grouped by shapes
20
Q

Single celled organisms

A
  • 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
Q

Multicellular organisms

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