On Friday(14/08/15), We had our Pathology class of the semester. It was an interesting and funny class as the lecturer continued with his comedian antics. This is a breakdown of how it went down :
* Definite Host: This is a host in which adult or sexually-reproductive stage of the parasite is found.
* Intermediate host- This is the host that habour the larva or asexually-reproductive stage of a parasite. It actually hosts' the parasite for part of the life cycle.
Vectors: They are organisms who transfer diseases from one host to another or from one environment to another. The types of vectors are: Mechanical and Biological vector.
Sources of infection are:
1. Fecal-Oral transmission.
2. Vertical transmission.
3. Eating of improperly cooked beef or fish.
4. Auto-infection.
5. Air-borne infections.
ADAPTAION OF PARASITES
Adaptations exhibited by parasites are:
1. Morphological adaptation
2. Life cycle adaptation
3. Immuno-logical adaptation.
4. Bio-chemical adaptation.
We then discussed Protozoa.
Protozoans are unicellular animals which are often microscopic. Some species are free living while some are parasitic.
Types of their life cycle are :
1. Simple/direct life cycle - They do not involve an intermediate host. Examples are flies, cockroach etc.
2. Complex/indirect life cycle: It involves two or more hosts. Examples are: Fasciola sp, Taenia sp. Etc.
The class had another funny end as there was an Adam and Eve scene where a guy and a girl shared an earphone. The lecturer scolded them and made a scene.... Lol..
