• PARASITOLOGY

  • The study of the interaction between parasites and their hosts
• PARASITES

  • An organism that lives on or in a host organism and gets its food from or at the expense of its host
• PROTOZOA

  • MASTIGOPHORA - THE FLAGELLATES
  • SARCODINA - THE AMOEBA
  • CILIOPHORA - THE CILIATES
  • SPOROZOA
• HELMINTHS

  • FLATWORMS (PLATYHELMINTHES)
  • TREMATODES (FLUKES)
  • CESTODES (TAPEWORMS)
  • ROUNWORMS (NEMAHELMINTHES)
  • THORNY - HEADED WORMS

   Parasitic Arachnids include:

  • TICKS
  • MITES
  • CHIGGERS
  • SCABIES
• PARASITISM

  • Common among children due to poor personal hygiene. Ex: lice infestation
• SCOTCH TAPE TEST


  Test for children to identify pinworm infestation
• WHIPWORM AND HOOKWORM


  soil transmitted helminths
• skin


  portal of entry of hookworm and plasmodium
• mouth


  portal of entry of whipworm and amoeba
• LARVAE


  stage of hookworms enters the human host
• small intestine


  this is where most parasites hatch
• head


  as long as this survives tapeworms will continue to grow and shed
• ASCARIS


  the mode of reproduction is sexual
• ANEMIA AND DISTENDED ABDOMEN


  it is the common signs and symptoms of children with helminthic infestation
• DEFINITIVE HOST

  harbors the adult or sexual stage of the parasite
• INTERMEDIATE HOST

  harbors the larval or asexual stage of protozoans and parasites
• ACCIDENTAL HOST

  is a living organism that can serve as a host
• FACULTATIVE PARASITE

  • is an organism that can be parasitic but does not have to live as a parasite.
• OBLIGATE PARASITE

  • has no choice to survive. It must be a parasite. Most parasites that infect humans are obligate parasites.
• INFECTIVE STAGE


  parasites are capable of entering the host
• DIAGNOSTIC STAGE


  it is the stage that parasite leaves the host
• PROTOZOA

  • From Greek protozoon word meaning “First animal”
  • Eukaryotic organisms that inhabit water, soil, and from animals
• PROTOZOAN INFECTION

  Adult patient complains of diarrhea with mucus, stool is blood - tinged, with fishy odor. From this signs and symptoms, the nurse already suspects amoebiasis.
• ASEXUAL

  • Multiple fission or schizogeny: Sexual
• Oocyst

  • Cyst formed by members of the phylum Apicomplexa used to produce new cells asexually
• trophozoite

  • A growing stage in the life cycle of some sporozoan parasites, when they are absorbing nutrients from the host.
• NUTRITION

  • All protozoa live in areas with a large supply of water. Some protozoa transport food across the plasma membrane.
• Ciliates take in food by waving their cilia toward a mouth-like opening called a

  CYTOSTOME
•  Ectoparasitic Insects include:

  • MOSQUITOES
  • FLEAS
  • LICE
  • BED BUGS
• CYSTS 


  A protective capsule produces by some protozoa under certain adverse conditions permits
