Bordetella bronchiseptica and cilia associated respiratory bacilli. transmitted by direct contact, aerosol and fomites. normal harbor theses organisms. asymptomatic except in weanlings and rabbits under stress. can cause mortality rates in guinea pigs and other rodents.
young rabbits, signs: constipation w/ mucous hypersecretion to profuse watery diarrhea. Impacted colon. hypothermia, depressed, crouched posture and rough hair coat. distended stomach with fluid and gas.
Enterotoxemia and Mucoid Enteropathy

mastisis "blue bag"

gram -, transmitted by ticks or undercooked meat, ZOONOTIC, causes leasions, pneumonia, LN enlargement, death. no signs.
oral is most common floor of the mouth and under tongue. infections usually self-limiting
highly contagious high mortality prevented by Vx. Signs: fever, rash, lacrimal and nasal discharge.
high mortality transmitted by insect vectors and direct contact. doesnt happen in rabbits younger than 2mo. death within 2 days - 2 weeks. Signs: pyrexia, anorexia, lethargy. Tx not effective must be culled.
Found in normal rabbits Signs: watery diarrhea, anorexia, dehydration. Mortality rate 80% in rabbits younger than 6mo. secondary infection E. Coli. Resulting in a higher mortality rate. Seizure like activity followed by death. Vaccine available.
Rotavirus Type A
ringworm is the only significant type of this disease. High zoonotic potential.
nematodes, cestodes, and protozoans
caused by protoza Encephalitozoon cuniculi. shed in urine asymptomatic but can have neurological signs leasions seen in brain and kideny's. no effective treatment
common neoplasia of domestic rabbits. This is the leading cause of death in pet female rabbits
