CREDENCE AND PARVOVIRUS CONTROL
Canine parvovirus is an important, potentially fatal, disease that requires control anywhere where vulnerable, unvaccinated or immune-suppressed dogs are kept. This includes breeding facilities, boarding kennels and veterinary clinics. Puppies are at great risk of contracting parvovirus, and all breeding related equipment and buildings must be suitably cleaned and disinfected before whelping to ensure the disease is controlled.
A laboratory trial in the USA was conducted to test the efficacy of Credence sanitiser against Canine Parvovirus (Cornell Strain) ATCC VR-2017. One tablet of Credence was dissolved in 3.8 litres of filter sterilised reagent grade deionised water, and used to test its efficacy against canine parvovirus. The virus was grown on test medium: Eagles minimal essential medium (E-MEM) supplemented with 5% heat-inactivated foetal bovine serum, 10 ug/ml of gentomycin, 100 ug/ml penicillin and 2.5 ug/ml fungizyme. Separate dry virus films were exposed to 2 ml of either water or Credence dilution at room temperature for 10 minutes. Following exposure, viral plating on the test media was conducted to assess viability of the canine parvovirus.
Table 1. Control of canine parvovirus (ATCC VR-2017) by Credence
| Virus Dilution | Control (water) | Credence solution |
| None | Positive | Not detected |
| 10-1 | Positive | Not detected |
| 10-2 | Positive | Not detected |
| 10-3 | Positive | Not detected |
| 10-4 | Positive | Not detected |
| 10-5 | Positive | Not detected |
The results of this study demonstrated that Credence is fully effective against canine parvovirus.
