Eimeria stiedae
Where does Eimeria stiedae inhabit?
Bile duct epithelium
C/s of hepatic coccidiosis
Young: death without clinical signs
Adult: Liver pathology with associated bloodwork abnormalities
Pathology of hepatic coccidiosis
Hepatomegaly with white, flat nodules or cords on surface of liver
Hepatic coccidiosis tx
Sulfa-based antibiotics
Good vermin prevention

Infection confers little immunity
Transmission of E. cuniculi
Urine/oral
C/S of E. cuniculi
Usually subclinical
Ataxia, torticollis, paresis, opisthotonus, tremors, convulsions
Histopath of E. cuniculi
Granulomatous lesions in KIDNEY, lung, liver, CNS
Tx for E. cuniculi
Fenbendazole + steroid (acute)
Chronic tx not helpful
Toxoplasmosis c/s in rabbits
Anorexia, fever, lethargy, CNS signs, death
How to tell difference between Toxo and E. cuniculi

E cuniculi is gram positive, purple with Carbol fuschin, Giemsa blue
Pneumocystis species specific to lagomorphs
Pneumocystis oryctolagi
Rabbit pinworm
Passaluris ambiguus
Prepatent period of Passaluris
56-64 days
Adult Passaluris inhabit what part of the GI?
Cecum and LI
How to sex adult Passaluris
Female has round esophageal bulb and long, pointed tail
Male has curved tail
Tx of Passaluris
