Canine Parvovirosis

Quantitative detection (real-time PCR) of canine parvovirus for a reliable diagnostics of canine parvovirosis even if the animal has recently been vaccinated with a high titer attenuated vaccine.

Reasons for testing

 Diagnostics of canine parvovirosis
 Assessment of the epidemiological risk (to reveal viral spread in a group)
 Assessment of environmental contamination and sanitizing monitoring in an infected environment

Test characteristics

 Real-time PCR
 Limit of detection
 Quantitative analysis
 Possible strain typing on request (this typing is not necessary for routine diagnostics)

Diagnostic samples

 Rectal swab (even post-mortem, dry swab without any preservative or culture media)
 Environmental swab

Result interpretation

Most of young dogs are infected with parvovirus. The only presence of virus, either wild or vaccine strain, does not lead to a reliable diagnostics if the viral load shed is not quantified. The quantitative results must be interpreted in a clinical and epidemiological context.

• Positive result :
  • Low or very low viral load : healthy carrier or a low load of vaccine strain is detected in the analyzed sample. Then, parvovirosis can be excluded.
  • High or very high viral load : compatible with parvovirosis. Such loads can be detected in some rare asymptomatic animals in a very contaminated environment (presence of clinical cases)
  • Medium viral load : eventually compatible with a recent vaccination with a high titer vaccine. Medium viral load are most often detected in cases of coinfections with coronavirus or in subacute forms of parvovirosis (duration of clinical signs > 10 days).
• Negative result : absence of virus or quantity lower than the limit of detection of the assay.
