Study Notes
Coccidiosis
- Caused by protozoa of the genus Eimeria, with two forms: intestinal and hepatic
- Infection occurs through the gastrointestinal tract
- Typically affects young rabbits, just after weaning
- Etiology:
- Liver coccidiosis: caused by Eimeria stiedae
- Intestinal coccidiosis: caused by E. magna, E. perforans, and E. irresidua
- Clinical signs:
- Loss of appetite and emaciation
- Bristly and matted fur
- Pale mucous membrane
- Blood and mucosa in feces
- Anemia
- Diarrhea in terminal stage, leading to body dehydration and pot belly
- Death
- Postmortem findings:
- Hepatic form: liver swelling, yellowing of mucous membranes, and urination
- Intestinal coccidiosis: soft intestinal contents, pinhead-sized lesions, and greyish-white flakes in the intestinal wall
Differential Diagnosis
- Pasteurellosis
- Tuberculosis
- Pseudotuberculosis
- Listeriosis
- Salmonellosis
Pasteurellosis (Snuffles, Pneumonia)
- Caused by Pasteurella species, including P. haemolytica and P. multocida
- Clinical signs:
- Chronic rhinitis (colds):
- Sneezing
- Clear, watery, or thick-yellow nasal discharge
- Soiled, discolored fur on the inner side of the front legs
- Snuffles (contagious catarrh):
- Frequent "snuffles" and forceful loud sneezing
- Mucoid to cream-colored purulent nasal discharge
- Purulent conjunctivitis and cloudy eyes
- Pneumonia:
- Elevated temperature
- Dullness and noisy forceful breathing
- Bluish ears and eyes
- Peritonitis:
- High temperature
- Fast and shallow breathing
- Reluctance to move due to sore abdomen
- Septicemia:
- Dead rabbit as the first sign
- Extreme weakness and high temperature
- Difficult breathing
- Bluish discoloration of the ears and skin
- Abscesses:
- Abscesses on the neck, dewlaps, ribs, and back
- Abscesses in the mammary gland of a doe
- Eye and middle ear infection:
- Partial or complete blindness
- Pronounced head tilt (may fall over easily)
- Inability to right themselves
- Mastitis:
- Swollen, bluish glands in lactating does
- Metritis:
- White discharge from the vulva
- Chronic rhinitis (colds):
Postmortem Findings
- Snuffles: Inflammation and necrosis of nasal passages
- Pneumonia:
- Consolidated inflamed area in the lungs
- Deep red, sharply demarcated lung lesion
- Whitish purulent material in the bronchi
- Cheesy material (fibrin) on the pleura
- Peritonitis:
- Yellow-white deposits (fibrin) on the peritoneum and abdominal cavity
- Abdominal organs adherent to the peritoneum and with one another
- Septicemia:
- Hemorrhages on body fat and heart muscles
- Enlarged body organs
- Bluish discoloration of body tissues
- Abscesses: Walled off abscesses containing white creamy cheesy pus
- Eye and middle ear infection:
- Normal eye structure obliterated by white or yellow pus
- White pus in one or both middle ears
- Mastitis: Swollen mammary gland with red to blue discoloration and congestion
- Metritis: Distended uterus contains white pus
- Arthritis: Cloudy fluid and pus present in the leg joints
Differential Diagnosis
- Salmonellosis
- Coccidiosis
- Bacteria such as E. coli, Pseudomonas, Listeria, and Proteus
- Staphylococcus aureus
- Streptococcus spp
- Actinomyces pyogenes
