Resources provided by the CSG Veterinary Science Group

The Mission of the CSG Veterinary Science Group is to:

  • provide a platform for the exchange of and access to specific veterinary knowledge and advise the CSG on veterinary matters related to crocodilian conservation;
  • contribute to advancing crocodile veterinary medicine and science; and,
  • provide support to animals under human care: farms and zoological or educational institutions, biologists and researchers that require veterinary support in their work such as sampling, anesthesia, surgery, etc., conservation, research, NGO and Government organizations investigating in-situ mortalities and population health status.
As part of this overall mission, the Veterinary Science group aims to compile information on selected topics, which will be posted on the CSG website as it becomes available (see Resources below).

Expertise Register

At the 23rd CSG Working Meeting (May 2014), attendees to the Veterinary Science Group side-meeting were asked to provide their details, so that a list could be posted on the CSG website. This list could serve as a resource for CSG members and non-members seeking advice on veterinary matters.

CSG members interested in being involved with the Veterinary Science Group and being included on the list (see below) should send their details (full name, e-mail, interest/expertise, country) to Dr. Cathy Shilton (Cathy.Shilton@nt.gov.au) or Dr. Paolo Martelli (paolo.martelli@oceanpark.com.hk). An updated list, including e-mail addresses, is available from Dr. Shilton or Dr. Martelli.

Fritz Huchzermeyer Veterinary Science Research Assistance Scheme

In honour of the late Dr. Fritz Huchzermeyer, in mid-2014 the Veterinary Science group established the "Fritz Huchzermeyer Veterinary Science Research Assistance Scheme" (FHVSRAS), with the specific goal of encouraging and assisting undergraduate and post-graduate students to undertake formal research to advance crocodilian veterinary science.

Dr. Tellez has also provided a Crocodile-Parasite Data Sheet (Excel format) that summarises current knowledge on crocodile-parasite interactions for different species. Literature cited in this document are available in "A Checklist of Host-Parasite Interactions of the Order Crocodylia".
