Envigo offers its clients numerous possibilities in setting up your health surveillance programs including testing profiles, frequencies of testing, number of animals to be monitored etc., all based on the FELASA 2014 recommendations. Our ISO 9001-2008 certified diagnostic laboratories are located in the UK, Italy and Singapore and include highly qualified microbiologists, (molecular) biologists and veterinarians.
The routine testing of laboratory animals includes the use of serology, bacteriology, molecular biology (PCR) and parasitology which is usually undertaken on live animals, which can be picked up from your facility by dedicated Envigo trucks. For shipping live animals to our labs, Envigo offers special filtered boxes including gel, so animals arrive in good condition at our lab. Alternatively samples can be sent by overnight courier; this includes the use of dry blood spot cards for serology. Please download our dry blood spot leaflet for detailed information.
There are some instances when the use of sentinel animals is recommended. Sentinel animals are those that are introduced to the main population specifically for the purpose of health monitoring, when it is difficult or inappropriate to sample animals from the main population. One example of such a case is when using racks of individually ventilated cages (IVC’s), where it may not be practicable to screen animals in every cage on the rack.
It is advised that sentinels are sufficiently exposed to the animal colonies (at least 6 weeks). Sentinel animals should be selected for immune responsiveness, susceptibility to pathogens of interest (and therefore negative for these organisms!), and ease of identification. Isolator bred and maintained sentinels from Envigo are at minimum free of opportunistic bacteria (often referred as FELASA Plus or SOPF quality). Full monitoring reports are normally provided within 10 working days from receipt of animals. If necessary, serology data can already be provided within 48 hours after receipt of the animals or samples. The reports can provide historical data for individual units and areas, if required. Keep in mind that as a customer you pay for the result – not the restesting!
