Contagious Parvoviral Infection in Rats

Parvovirus in Rats

 

Parvoviral infection is a highly contagious but rarely encountered viral disease in rats. When it does occur, the parvovirus infection is very severe and recovery of the affected rat is uncommon, as the severity of this infection often leads to death.

 

The parvovirus infection spreads through direct contact, and by contact with contaminated cage items, such as litter, bedding, etc. Infection is usually symptomized in the digestive system as bloody diarrhea and vomiting, and in the reproductive system of pregnant female rats as stillbirths, small litters, runting (weak, low weight newborns with failure to thrive), hemorrhages, and infertility. In advanced cases, parvovirus can also lead to death of brain cells.

 

There is no available treatment for this condition; only supportive care is possible with the help of fluids and electrolytes. Prevention of this viral infection, by means of good hygienic practices, is essential to avoid the loss of your pet as a result of the parvovirus infection.

 

Symptoms and Types

 

  • Severe bloody diarrhea and vomiting in the initial stages of infection
  • Pregnant females may deliver stillborn pups or give birth to small litters, especially during the initial stages of infection
  • Recovering females may develop infertility or runting (delivery of weak, underdeveloped newborns, with failure to thrive)
  • Infertility in infected rats due to death of cells in the gonads (male and female)
  • Hemorrhage in male rats, with a high rate of fatality
  • Death of brain cells (due to involvement of the nervous system)

 

Causes

 

  • Contact with another infected rat or its feces or urine
  • Soiled and contaminated bedding material
  • Unhygienic living conditions, with a lack of regular cleansing and disinfecting of the cage and surroundings 

 

Diagnosis

 

A diagnosis can be confirmed by your veterinarian based on the clinical symptoms observed along with advanced serological tests.
