Hamster Diseases Flashcards
What is the etiology of proliferative ileitis (wet tail)
lawsonia intracellularis
whats are the hosts of proliferative ileitis
17-30 day old hamster
what are the predisposing factors for proliferative ileitis
shipping, crowding, improper diet, stress
What are the clinical signs for the less acute version of proliferative ileitis
failure to gain weight. bloody diarrhea, prolapsed rectum, colon. can die from ileal obstruction, intussusception, peritonitis.
what are the clinical signs for the acute version of proliferative ileitis
lethargy, matted coat hair, hunched, anorexia. watery diarrhea, emaciation, dehydration. high morbidity and mortality. death within 48hrs
what is the treatment for proliferative ileitis
fluid PO, SQ. Bismuth Salicylate (pepto bismol 1-2ml PO), antibiotics (metronidazole, enrofloxacin, tetracycline)
what is the etiology if clostridium enterotoxemia
clostridium sp (not piliforme) especially clostridium difficile
what are the hosts of clostridium enterotoxemia
hamsters, rabbits, guinea pig
what is the pathogenesis of clostridium enterotoxemia
clinical signs: occur spontaneously or following the administration of antibiotics (penicillin).
Describe clostridium infection that occurred spontaneously
reason unknown for colonization of colon by clostridia.
describe clostridium infection following antibiotics
alteration of intestinal flora. overgrowth of clostridia. toxin producing. cause diarrhea, dehydration, rough hair coat, hunched, high mortality rate
what are the other two diseases
bacterial pneumonia
tyzzers disease
What is lymphocytic choriomeningitis
refer to mouse lecture
what two endoparasites parasitize the hamster
pin worms : syphacia mesocriceti, obvelata and muris
Tapeworm: (direct: zoonosis): hymenolepis nana (direct) and diminuta (indirect)
what ectoparasites parasitize the hamster
demodex
how do you diagnose demodex
deep skin scraping
is demodex contagious
no
what are the clinical signs of demodex
rarely associated with clinical signs. no pruritis. dermatitis, alopecia (scaly skin, scabs) on back, rump. Secondary to malnutrition, systemic disease
who is demodex more common in
males > 1.5yrs of age
How do you treat an impaction of cheek pouches
remove materials inside, flush, antibiotic ointment
Describe amyloidosis in hamsters
high incedence. female > male increase with age. Occurs in all organs, but with a predilection for kidneys. most common cause of death in old hamsters
Describe polycystic disease in hamsters
congenital, cysts in liver, pancreas, epidydimis, seminal vessicals. doesn’t cause clinical signs.
describe atrial thrombosis in hamsters
in older hamsters. causes severe dyspnea due to congestive heart failure
