The Laboratory Xenopus sp. Care Manual
by Sherril L. Green, DVM

Even though the Xenopus is one of the most popular non-mammalian animals used in biomedical research, their value in the lab suffers from a lack of standardization regarding their optimal care, breeding, and housing. Filling the need for such a reference, this book provides researchers, technicians, and animal caretakers with a practical, step-by-step manual that emphasizes the human care and use of captive clawed frogs in basic as well as biomedical and toxicological research...read more

Worldwide Amphibian Concerns

There are environmental concerns about the precipitous worldwide decline of amphibian populations. New O.I.E. (World Organization for Animal Health) regulations will soon mandate disease testing of amphibians prior to shipment. Two disease organisms of particular concern are the Chytrid fungus and Ranaviruses.

Nasco has chosen to be pro-active about these new rules and have tested our Xenopus colony in advance of the mandated requirement. We are pleased to report that all of our sample frogs received a clean bill of health in February 2013.
