<FlashCard questions="6">
|q1= What types of parasites cause cryptobiosis in fish?
|a1= Biflagellate protozoa
|l1= Cryptobiosis#Introduction
|q2= Which species is the ectoparasite and where does it reside?
|a2=
*''C. branchialis''
*Lives on the gill epithelium of its host
|l2= Cryptobiosis#Introduction
|q3= How are the bloodborne parasites transmitted between fish?
|a3= By bloodsucking leeches
|l3= Cryptobiosis#Distribution
|q4= How does ''C. salmositica'' cause anaemia? (Hint:There are two mechanisms)
|a4=
*Secretes haemolysin which directly destroys red blood cells.
*Release of antigens when the complement system destroys the parasite, causing immune complexes to form and attach to erythrocytes, causing haemolysis.
|l4= Cryptobiosis#C. salmositica - Haematozoic Endoparasite
|q5=How can parasites be detected in tissue samples?
|a5= Both techniques look for moving/fixed flagellate organisms.
*Wet mounts can be used under bright field or phase contrast microscopy
*Slides can be fixed in ethanol and examined under light microscopy with Giemsa stainins
|l5= Cryptobiosis#Diagnosis
|q6= Which parasites can be vaccinated against?
|a6=
*''C. bullocki''
*''C. salmositica''
|l6= Cryptobiosis#Treatment and Control
