Q

Chicken: Sample and method

A

Giemsa (smear) for the zoites-pale body and the nucleus is visible
Kinyoun: pink unsporulated oocysts in fresh faeces
Iodine: grey sporulated oocyst
Flotation method of faecal sample

Q

necatrix

A

Jejunum and ileum
Most dangerous- lots of unclotted blood
Scattered white spots

big mass of RBC’s
no structure
damage deeper than subep!
