canine parvovirus an corona virus Flashcards
what 4 things should you consider about the etiology of CPV
a) highly contagious DNA viral disease
b) spread by dog to dog contact and ingestion
c) source of infection is fecal matter from infected dogs
d) overcrowding, poor nutrition and poor sanitization can make this disease worse
what 5 things should you consider about CPV1
a) in 1967 it was isolated from the feces of military dogs
b) it is also known as minute virus of canines
c) it is only seen in puppies from birth to 42 days old
d) this the myocardium form of CPV affecting the heart
e) clinical signs include diarrhea, vomiting, dyspnea, and constant crying
what 5 things should you consider about CPV2
- this form was not found until 1978 in the US and is a contagious enteric disease affecting the GI tract
- any breed, age and gender can get this but young dogs are most affected
- attenuated and killed vaccines of CPV2 are available and they are long lasting, and safe when used with other vaccines
- CPV2 vaccines do not protect puppies from CPV1 infections
- clinical signs include depression, loss of appetite, vomiting, sever bloody diarrhea, high temperature and lethargy
what 3 key points should you consider about the parvovirus
a) signs appear 5-7 days after the dog is exposed to the virus
b) most deaths occur within 48-72 hours following the start of clinical signs
c) puppies less than 5 months have an increased risk of getting this disease
what 3 things does the infection depend on whether or not it actually happens
host vitality, virulence of the virus and the environment
what is virulence of the virus
it is how many viral particles the host is exposed to
what is host vitality
it is an animals immune experience and vaccination status
what are the environmental factors
a stressful environment will reduce host vitality and a dry environment will reduce the number of viral particles
what 6 things should you consider about the incubation of CPV
a) the virus enters the body seeking the nearest rapidly dividing group of cells
b) lymph nodes of the throat multiply to large numbers
c) significant amounts of the virus released free into the bloodstream
d) over the next 3-4 days the virus seeks new organs containing rapidly dividing cells such as bone marrow and delicate intestinal cells
e) in the bone marrow the virus destructs the young cells of the immune system
f) the GI tract is where most of the damage is done because the body cant produce new cells and both the villi and microvilli cant absorb the nutrients needed
what are the 2 ways CPV kills
a) diarrhea and vomiting lead to extreme fluid loss and dehydration until shock and death result
b) loss of intestinal barrier allows a bacterial invasion of potentially the entire body, septic toxins from those bacteria result in death
what 4 things should you consider about the diagnosis of CPV
a) symptoms and history
b) CBC-marked lymphopenia and neutropenia
c) Fecal Elisa test
d) serology titer 1 of 10000
what 5 things should you consider about the treatment of CPV
a) isolation
b) stop dehydration by replacing electrolytes and fluid losses
c) control V and D
d) prevent secondary infections with antibiotics
e) keep warm
what 2 things should you consider about the corona virus
a) it is a highly contagious GI disease most commonly found in puppies less than 4 months
b) it has a unique relationship with CPV
what 5 thongs should you consider about CCV symptoms
a) loss of appetite
b) V and D although blood is rarely seen
c) secondary bacterial infection
d) dehydration
e) differentiated from CPV by the fact that CCV does not cause the total number of WBC in circulation to reduce
