- Reported with Pasteurella multocida
infection. (J4.203.w3)
- "Predisposing factors, such as build up of ammonia fumes in the rabbit house, ambient temperature changes and drafts, reproduction, older age, existence of carriers, and poor sanitation contribute to the likelihood of development of clinical
pasteurellosis." (J4.203.w3)

| General Description |
- "Ovarian abscesses commonly caused by P. multocida
are often found during groos and microscopic examinations at the end
of reproductive and teratology studies." (B534.6.w6b)
Clinical signs
- An affected rabbit was bright and alert, with a distended abdomen.
- Weight gain and abdominal distention had developed over a period
of six months.
- Palpation of the abdomen revealed that the caudal half of the
abdomen was filled by a mass.
- Radiography revealed distinct multilobulated soft tissue opacities
in the abdominal cavity caudal to the kidneys and displacing the
abdominal viscera and right kidney cranially.
- Ultrasonography revealed multilobuled masses; the walls were well
defined and there were cyctic spaces of variable echogenicity.
(J4.203.w3)
Clinical pathology
- Normocytic, normochromic anaemia. (J4.203.w3)

Diagnosis
- In a reported clinical case: on laparotomy (Laparotomy in Rabbits), the ovaries were enlarged (10 x 8 and 8 x 5 cm),
containing pasty inspissated exudate, tan in colour. (J4.203.w3)
Pathology
Gross Pathology
- Ovarian abscesses, usually containing a thick, creamy white to tan
exudate, and sometimes surrounded by a fibrous capsule. (B534.6.w6b)
- Ovaries: mottled white-brown, consisting of cystic cavities
containing chalky white inspissated exudate.
- Uterus: walls thickened, horns containing tan-coloured pasty
material with a thin encapsulating layer of red-tan fibrous
tissue, and body containing inspissated tan exudate.
Histopathology
- Ovarian abscesses, may be an incidental finding in rabbits at the
end of toxicological or reproductive studies. (B534.6.w6b)
- In a doe with Pasteurella multocida pyoendometritis,
pyosalpingitis and ovarian abscesses: (J4.203.w3)
- Ovaries: normal tissue replaced by fibrous connective tissue
surrounding abscesses.
- Uterus: subacute suppurative endometritis and subacute
suppurative salpingitis
- Renal: multifocal subacute pyelonephritis (mild)
- Cardiac: Pericardial effusion (mild)
- Liver: Extramedullary haematopoiesis.
- Gram-negative rods in the ovarian abscess exudate.
- Culture: Pasteurella multocida isolated from
ovarian exudate. (J4.203.w3)
