Adenovirus Flashcards
Morphology of Adenoviruses
non enveloped, double stranded, icosahedral
avian adenoviruses
aviadenovirus
mammalian adenoviruses
mastadenovirus
adenovirus of vertebrates
atadenoovirus
amphibian adenovirus
siadenovirus
causes infectious caninehepatitis
canine adenovirus serotype 1
involved in infectious tracheobronchitis
canine adenovirus serotype 2
Associated with quail bronchitis, inclusion body hepatitis and hepatitis hydropericardium syndrome
fowl adenovirus
Causes egg drop syndrome in laying hens
duck adenovirus A
cause marble spleen disease in pheasants
Turkey adenovirus A
important source of infection of avian adenovirus
feces
IBH affected animals
broilers, rearing pullets
Mortality of IBH
10 to 30 percent
disease is characterized by a drop in egg production, by the laying of abnormal eggs or by a failure to peak
egg drop syndrome
egg drop syndrome is seen between start of lay and?
36 weeks of age
lesions of IBH are found in
oviduct, pouch shell gland
IBH intranuclear inclusions are commonly seen in
epithelial cells of pouch shell gland
Suitable specimens for isolation of the Aviadenovirus
duck kidney or fibroblast cells, oviduct, material from pouch shell gland
causative agent of infectious canine hepatitis
CAV 1
CAV 2 is more commonly associated with
respiratory disease
causes infectious canine hepatitis or Rubarths disease
Canine adenovirus type 1
affected area of CAV 1
liver, vascular endothelium
transmission of CAV 1
urine, feces, saliva
The immune response usually eliminates CAV 1 from host tissues by how many days
14 days after initial infection
incubation period of CAV 1
7 days
True or False. Dogs of all ages are susceptible to CAV 1
TRUE
mortality rate of mature dogs to CAV 1
10 to 30 percent
mortality rate of young pups to CAV 1
100 percent
CAV 1 infection where death occurs so rapidly that poisoning may be suspected
peracute disease
True or FALse. Dogs infected with CAV 1 has life long immunity once recovered.
TRUE
the enzyme which causes the hepatic tissue unsuitable for CAV 1 isolation
arginase
how does arginase affect CAV 1 tissue culture
through inhibition of viral replication
Affected dogs present with signs typical of canine infectious tracheobronchitis
CAV 2
CAV 2 is shed for how many days post infection
8 to 9 days
