Electron Microscopy

Recent fee changes

Electron microscopy is used to detect and identify viruses in clinical specimens, such as feces (rotavirus, coronavirus, parvovirus, calicivirus, etc.), skin lesions (poxvirus, papovavirus) and tracheal and conjunctival swabs/scrapings (herpesvirus). At least 1 ml of feces, more if possible, should be submitted in leak-proof containers and submitted refrigerated. Do Not Freeze! Do not use plastic gloves or OB sleeves as containers! Plastic bags are acceptable if specimens are double bagged. Fecal swabs are often acceptable for detection of canine parvovirus/coronavirus. Swabs and excised skin lesions should be placed in tightly closed containers with a drop of water to prevent drying.

Samples should be collected early in the course of the disease as the concentration of virus shed will decrease rapidly with time. In the case of herd problems, samples should be collected from more than one animal including an apparently healthy individual and several others in different stages of the disease. Multiple samples will also help in detection of viruses that are shed intermittently, as is frequently the case with infection by rota/reoviruses.

Results are available within 24 hours or less, depending on when specimens are received.

Plant Identification (includes algae, "mushrooms", fungi)
Submit entire plant including flowers, seed pod and roots. Formalin fixed specimens lose their color making ID difficult. Please submit some fresh specimens wrapped in paper, not plastic, and refrigerated. Submit samples to Tifton Diagnostic Laboratory. Samples may also be submitted to The University of Georgia Herbarium in Athens. Contact 706.542.3732 for further information.
