A parasite maintains and multiplies at the expense of the host with which it lives Ecto parasite : Parasites that exclusively live of the skin of their host (ticks) Endo parasite : Parasite that live inside their hosts : intestines, blood, tissues and organs (worms) Protozoa: unicellular organisms eukaryotic cell that lack some of the familiar organelles Metazoa: multicellular organisms eukaryotic cells that has specialised cells/organs (brain, digestive and reproduction system)

Introduction parasitology

Q: What is the difference between intra- and inter- species associations?

Intra -species association: between animals of the same species Inter -species association: between animals of different species

Q: What is the difference between the final and intermediate host?

Final host : organism in which the adult parasite is present and where sexual reproduction takes place Intermediate host : organism in which the parasite undergoes a specific development and where asexual reproduction might occur but not sexual reproduction

Q: What is the difference between a vector and a reservoir?

Vector : invertebrates organism that facilitates the transmission from one host to the next Reservoir : some parasite occur in both human and animals. These animals are called reservoir hosts and are a source of infection for humans (zoonotic infections)

5 important questions on Introduction parasitology

What is the difference between intra- and inter- species associations?

Intra-species association: between animals of the same species
Inter-species association: between animals of different species

What are the differences between inter-species associations?

Mutualism

mutually beneficial association between 2 different species

Communalism

both species can live independently from each other, but one (or both) may gain advantage form the association

Parasitism

being dependent on host and benefit from the association at the host's expense

What is a parasite?

A parasite maintains and multiplies at the expense of the host with which it lives

Ectoparasite: Parasites that exclusively live of the skin of their host (ticks)

Endoparasite: Parasite that live inside their hosts: intestines, blood, tissues and organs (worms)

Protozoa: unicellular organisms

eukaryotic cell that lack some of the familiar organelles

Metazoa: multicellular organisms

eukaryotic cells that has specialised cells/organs (brain, digestive and reproduction system)

What is the difference between the final and intermediate host?

Final host: organism in which the adult parasite is present and where sexual reproduction takes place

Intermediate host: organism in which the parasite undergoes a specific development and where asexual reproduction might occur but not sexual reproduction

What is the difference between a vector and a reservoir?

Vector: invertebrates organism that facilitates the transmission from one host to the next

Reservoir: some parasite occur in both human and animals. These animals are called reservoir hosts and are a source of infection for humans (zoonotic infections)
