Symbiosis define

Association of different organism of different species living together. There are two types of symbiosis.

What are the two symbiosis?

1. Commensalism


2. Mutalism

Commensalism define

One organism that benefits the other one by living off it

Mutalism define

Beneficial to both


Ex. Bacteria in the intestine

Parasitism define

One organism is benefited and the other organism is harmed

Host

Another organism the parasite is living on

There are two types of host what are they?

1. Intermediate


2. Definitive

Intermediate define

Parasite passes larvae stage or asexual reproduction stage

Definitive stage

Parasite where it passes


Lives at adult stage or asexual stage

Reservoir

Can be a animal, insect, lake, land


Harbors the parasite where a host can become infected

It harbors parasites

Host specificity

Range of diff host in which parasite can develop


Some can only develop in dogs and cats

Incidental

Affection of host other than it's hoat

Zoonotic

Contagious from pets to humans

Obligatory parasite

Parasite that cant live away from a host

Facultative parasites

Live independently with out host

Carrier

Host that harbors a parasite that can be transmitted to another host and they show no signs or symptoms

Vector

Transport parasites from infected host to non-infected host

What are the two types of vectors?

1. Mechanical


2. Biological

Mechanical

Transport parasite (passively) no growth or development occurs in the insect

Biological

Essential in the life cycle of parasite and development or change of parasite that takes place in the vector

Life cycle

How the parasite lives, thrives and mature

Life cycle stages

A. Diagnostic stage


-what is identifiable that the doctor can make a diagnosis


B. Infective stage


- parasite that enter host and continue infection, become pathogenic


C. Method of infection


- how it got into the host


- portal of entry/portal of exit


D. How parasite affect host


- give off secretary that ia toxic


Parasite and how it affects the host body

1. Enzyme destroys tissue


2. Gets into the RBC it burst them amd destroys them


3. Attached to organs witb suckers and causes irritation


4. Travel to diff parts of the body


5. Cause perforation to intestine


6. Cause intestinal problems such as obsession


7. Need nutrients


How does the host affect the parasite

1. Good immune system- antibodies will be able to fight back


2. Ethnic differences will help thrive the parasite.
