BASIC PARASITOLOGY
•The science that deals with organisms that take up their abodes• Temporarily or permanently• On or within other living organisms• Procuring food with the relationship
of these organisms to their hosts2Untan-neurosains sem 4-2011
CLASSIFICATION
• Ecto-parasite :
Parasite that lives outside the body of the host (infestation)
• Endo-parasite :
Parasite which lives within the body of the host (infection)
3Untan-neurosains sem 4-2011
• Obligate-parasite :
Parasites are completely dependent upon the host
e.g : Ascaris lumbricoides
• Facultative-parasite :
Parasites are capable of leading both a free and a parasitic existence upon the host
e.g : - Strongyloides stercoralis, Tick
CLASSIFICATION

Parasite
Phytoparasite Zooparasite Spirochaeta Virus
Protozoa Metazoa Helminths Arthropods
Nematode Trematode Cestode

HOST
• Harboring parasite species• Usually a larger organism that
provides physical protection and nourishment
6Untan-neurosains sem 4-2011
DEFINITIVE HOST
• The host that harbors the adult or sexual stage of the parasitee.g : - Ascaris lumbricoides man
• Intermediate host :
Another animals that take place part or all of the larval or asexual stage e.g : - Plamodium mosquito man
- Filaria man mosquito
7Untan-neurosains sem 4-2011
RESERVOIR HOST
• Animals that harbor the same species of parasites as man and act as additional sources of human infection
E.g : - Trichinella spiralis Rh : pig, rat, bear
- Brugia malayi Rh : monkey, cat, dog
8Untan-neurosains sem 4-2011
Intermediate hosts
• Transmission in a passive capacity.• Part or all of the larval or asexual
stage may take place in another animal such as the snail , Cyclops or Diaptomus.
9Untan-neurosains sem 4-2011
VECTORS
• Hosts that transmit parasites to man
e.g. : mosquitos in malaria / filariasis
glossina in sleeping sickness Africa
ZOONOSIS• Animal diseases which can be transmitted
to humane• e.g.:Blantidiosis (Balantidium coli)

Protozoa Metazoa Helminths Arthropods
Nematode Trematode Cestode
11Untan-neurosains sem 4-2011
NEMATHELMINTHES
• Roundworm , unsegmented• Posses a body cavity• Have a complete digestive system • The sexes are separate
12Untan-neurosains sem 4-2011
PLATYHELMINTHES
• Flatworms • Bilaterally symmetrical • Leaf – shaped or band – shaped • Without a body cavity • Have no digestive tract • Hermaphrodite
13Untan-neurosains sem 4-2011
Trichuris trichiura
Cacing dewasa Telur
Fasciolopsis buski
Cacing dewasa
Protozoa• an unicellular animal cell • living either in colonies or solitaire which is
able to perform all physiological function of its own
15Untan-neurosains sem 4-2011
Classification :
E Rhizopoda
E Mastigophora/Flagellata
E Cilliophora/Ciliata
E Sporozoa

Reproduction
§ asexual : binary fission, schizogony, cyst formation
sexual : Gametogony, sporogony, conjugation
alternating asexual and sexual
18Untan-neurosains sem 4-2011
Pathology
Tissue damage by :• invasion • enzyme • toxin • immune response
19Untan-neurosains sem 4-2011
Infection
• Acute fatal• Sub clinical• Chronic/latent• Relapse/ acute exacerbation
20Untan-neurosains sem 4-2011
Entomology
deals with insects, arachnids, and other arthropods which cause pathology / role in transmission infective agents
The arthropods involved may be as :1. the causal agents (S.scabiei)2. intermediate hosts (cyclops)3. vectors. (Aedes, Anopheles)
