What is dimorphism
Where fungi can show either yeast or hyphal form
Give and example of fungal infection
Ring worm
What are protisa defined as
single cells/unicellular eukaryotes
What are protozoa’s role
Consume bacteria - control bacteria population/biomass
What are thee 3 main classifications of protozoa
Sarcomastigophora
Ciliophora
Apicomplexa
What are the two subphylum Sarcomastigophora can be split into
Mastigophora
Sarcodina
What are the difference between Mastigophora and Sarcodina
Mastigophora - move by flagella
Sarcodina - move by pseudopodia (false feet)
How do Ciliophora move
Move by short hair process/cilia
How do Apicomplexa move
By body flexion - use apical body to invade host cell
Which classification of protozoa are all parasitic
Apicomplexa
What are cats classed as in the life cycle of toxoplasma
Definitive host
Who are the intermediate hosts of the life cycle of toxoplasma
Other animals/humans
What are oocysts
Cysts with zygotes
What do oocysts develop into after being ingested by intermediate host
Tachyzoites
