Pros and cons for Zinc Sulfate
-floats protozoan organisms with the least amount of distortion

-may distort helminths
Pros and Cons of sugar solution
-does not distort helminths
-does not crystalize
-long self life

-ova rise slowly
may distort fraglie larva tramatodes or cysts
-attracts bugs

How are parasite usually reported?
-Life cycle
-Zoonotic significance
-Signs and symptoms
What are Three types of parasites?
Parasite- An organism which lives on(ectoparasite) or in(endoparasite) another living organism (host) at whose expense it obtains some advantage

Erratic or Aberrant Parasite- An organism which wanders from its usual site of infection

Free-living parasite- An organism which is capable of living in the enviroment and leading a non parasitic existance
What are Four types of hosts?
Definitive host- a host that harbors the adult, sexually mature stages of a parasite, usually defined as the final host

Intermediate host- This host harbors at least on developmental stage of the parasite before trasferrign it to another host(Without this host the parasite would not exsist)

Parentenic host- This host harbors a stage of the parasite which does not undergo a developmental stage(ex.a mouse)

Resivoir host- a vertabrate host in which a parasite or disease occures naturally and is a sourse of infection( ex. A dog who is harboring heartworm is carrying the infection and could expose it to any mosquito(untermediate host) that bites it)
What is a carrier host?
some resivoir hosts act as carrier hosts. That means that they carry the parasites but they show no signs of illness
