| Etiology
Deoxyribonucleic acid (DNA) viruses belonging
to the family Parvoviridae, which is thermostable and resistant
to wide variety of physical and chemical agents.
Transmission
- Direct contact or through fomites as the virus is present in
all secretions of the affected animals.
- Transplacental infection can also occur.
Clinical Signs
There is rapid onset of the disease associated with
vomition of blood tinged ingesta mixed with frothy mucus.The common
signs are-
- Biphasic feverand anemia
- Profuse and persistent blood tinged diarrhea
- Depression and blindness
In peracute cases, the affected animals may die suddenly without
exhibiting any cllinical signs, while in chronic cases, the disease
may be prolonged with persisstent diarrhea, dehydration and death.
If the cat survives for 48 hours, its chances for recovery are much
better.
Pathology
The carcass were invariably dehydrated and the blood was dark
and tarry in colorand thick in consistency. The mucosa of the
entire iintestinal tract was hyperaemic but the ileum and colon
were covered with diptheritic membrane.
Diagnosis
- ELISA test to detect antibodies
- Virus isolation
- Parvo
Dipstick Test (Cypress Diagnostics, Belgium)
for detection of parvo virus in fecal sample.
- Leucopenia particularly agranulocytes.
- Rapid onset and febrile reaction.
Specimens to be sent to Lab
- Fecal sample or rectal swabs for virus isolation and Parvo Dipstick
Test.
- Heparanised whole blood for leucopenia
- Intestinal pieces, lymphnode, spleen and bone marrow in 10 %
formol-saline separately.
