Infections of research animals can often lead to subclinical diseases without visible clinical signs. In this state, transmission of the disease between the animals is possible. Furthermore, subclinical infections can cause effects and reactions in the organism, regarding e.g. the immune response, growth of the animal, behavior and so on. Depending on the use of the animals and the scope of research, these changes may have an impact on the experimental results, reproductive outcome, performance and other parameters.

Infections in the animals can also contaminate biological material such as transplant tumors, tissues, cell lines or sera with infectious agents. When these materials are used, also the pathogens can be transmitted.
Furthermore, some microorganisms are known as potential zoonotics and can be transmitted between animals and humans.

Based on this, a regular Health Monitoring of research animal facilities is recommended.
Please do not hesitate to contact us for support for an individual health monitoring program for your animal facility.

    Sample Shipment

    The samples should be stored in the respective tubes. The tubes must be tightly closed. Dry Blood Spot cards should be dryed before closing. All samples must be clearly labelled.

    In general, direct samples of animals should be sent as soon as possible on the day of sample taking. When the shipment of samples on the same day is not possible, please store the direct samples as follows:

    Sample Storage conditions
    Feces samples PCR For a few hours cooled, overnight in the freezer (-20°C)
    Feces samples bacteriology Overnight in the refrigerator
    Pharynx swab PCR If not sent immediately, dry swab under sterile conditions approx. 2 hrs before placing in the tube; thereafter, store for a few hours or overnight in the refrigerator
    Pharynx swab bacteriology Overnight in the refrigerator
    Serum samples max. 1 day at room temperature, up to 5 days in the refrigerator, otherwise in the freezer (-20°C)
    DBS card After drying, store for a few days (max. one week) at room temperature; dry and clean conditions
    Sticky swab (fur) Overnight in the refrigerator


    For fresh samples with a short tansportation distance, shipment at room temperature is possible. Otherwise, the samples should be cooled during shipment.

    Biological material must be packed with three layers for shipment. This means that the tubes need to be wrapped with two additional materials, such as a second, bigger tube or a plastic bag which are than placed in a bubble-wrap envelope, or in case of higher sample numbers, in a styrofoam or cardboard box.

    Please always send the complete analytical form with the samples. The form is available on the homepage or can be sent to you per email, on request.

    To ensure fast processing of your samples, please contact MicroBioS in advance.
