A very basic introduction to parasitology. It includes the terminologies used in the parasitology, and fields of parasitology!

1. INTRODUCTION TO
PARASITOLOGY

2. PARASITOLOGY

Parasitology the branch of biology concerned with the
phenomenon of dependence of one living organism
on another.

It’s study of parasites, their hosts, and the relationship
between them.

3. PARASITE

An organism that lives on or in its host, which is
usually a larger organism, that provides physical
protection and nourishment.

An organism that has sustained contact with another
organism to the detriment to the host organism.

4. FIELDS /BRANCHES OF
PARASITOLOGY

Medical parasitology

Veterinary parasitology

Structural parasitology

Quantitative parasitology

Parasite ecology

Conservation biology of parasite

Taxonomy and phylogenetics

5. PREDATOR

Organism that attack another living animal, not
necessarily killing them. ( attacker)
PREY

They are the victim.

6. HOST

The organism from which a parasite obtains its nutrition
and/or shelter.

Intermediate host- is used normally by a parasite
in the course of its life cycle
and it which it may multiply
asexually and but not sexually

7. 
Definitive host- is the host in which the sexual
reproduction of parasite takes
place.

Reservoir host- is an organism in which a
parasite that is pathogenic for
some other species, lives and
multiplies usually without
damaging its host.

8. SCAVENGERS

Devouring those dead of natural causes or taking the
leavings of the predator.
SYMBIOSIS

Living together in more or less intimate association or close
union of two dissimilar organisms

From the Greek symbiosis which means the state of living
together.

9. DIFFERENT FORM OF SYMBIOSIS

Commensalism
- means eating at the same table
- association that is beneficial to one partner
and at least not disadvantageous to the
other.
- a relation between two kinds of organisms
in which one obtains food or other benefits
from the other without damaging it.

10. SPECIALIZED TYPE OF
COMMENSALISM

Mutualism- association is beneficial to booth.

Parasitism- symbiotic relationship in which one
organism , the host is to some
degree injured thru the activities of
the other.

11. VECTORS

Hosts that transmit parasites to man.
BIOLOGIC VECTORS

those that are essential in the life cycle.
PHORETIC OR MECHNICAL VECTORS

Those that are not essential in the life cycle.

12. ZOONOSIS

Disease of animals (literally)

Disease of animals that are transmissible to man
CLASSIFICATION OF ZOONOSIS

Euzoonosis- Common to man and reservoir
host.

Parazoonosis- man is infrequent host and
incidental

Anthropozoonosis- infection acquired by man
from other vertebrates.

13. 
Zooanthroponosis- human infection that maybe
acquired by other vertebrates

Obligate parasite- cannot exist without the host

Facultative parasite- can be free living or parasitic

Amphizoic- free living amoeba that may invade
and colonize the brain and other
sites( Naegleria and Acanthomoeba)

14. 
Spurious- Free living parasites or organisms that
parasitize other hosts,
- they merely passed the intestine ,
- recovered in living or dead state from
he human feces.
