Zoo freezes genetic samples to save animals from extinction
Jaguars are among the threatened animal species that have been successfully cryopreserved in the Nature's SAFE biobank.
Chester Zoo partners with Nature's SAFE to cryopreserve threatened species. 

Conservationists at Chester Zoo have started to freeze tissue samples from some of the world's rarest creatures in a bid to save them from extinction.

The scientists have joined forces with leading animal reproduction experts to establish Nature's SAFE (Saving Animal From Extinction) – one of Europe's largest living biobanks for the future regeneration of animals. 

It involves taking ovarian and testicular tissue samples from deceased animals, and keeping them frozen at -196C, the point at which the cells enter a state of suspended animation.

The hope is that as reproductive technologies advance, the samples could help to further conserve species globally by generating sperm and eggs.

Nature's SAFE has already successfully cryopreserved multiple cell types from more than 100 highly threatened animal species, including the Eastern black rhino, mountain chicken frog, jaguar and Javan green magpie.

Dr Sue Walker, head of science at Chester Zoo and co-founder of Nature’s SAFE, explains: “With gene pools and animal populations continually shrinking in the wild, the work of modern conservation zoos like ours has never been more important. 

“Technologies, such as cryopreservation, offer us a new, critical piece of the conservation puzzle and helps us provide a safeguard for many of the world’s animals that, right now, we’re sadly on track to lose.” 

There are currently more than 142,500 species on The IUCN Red List, with more than 40,000 species threatened with extinction. Working closely with zoos across Europe, Nature's SAFE aims to provide a vital insurance policy for endangered wildlife to protect it for generations to come.

Vets to run marathon for World Animal Protection

News Story 1
 Two recently graduated veterinary surgeons will be running the London Marathon in April to raise money for the charity World Animal Protection.

Alex Bartlett and Maeve O'Neill plan to run the race together if they are given the same start times.

Dr O'Neill said: "You're always limited in what you can do to help animals, so it is nice to raise money for a charity that helps animals around the world."

Dr Bartlett added: "I have never run a marathon before and am excited to run my first one for such a good cause!"

Both Dr Bartlett and Dr O'Neill have fundraising pages online.

BSAVA releases new Guide to Procedures

The British Small Animal Veterinary Association (BSAVA) has published a new edition of its Guide to Procedures for Small Animal Practice.

It has added four new procedures; cystostomy tube placement, endotracheal intubation, point-of-care ultrasound and wet-to-dry dressings.

BSAVA says that it is an essential step-by-step guide to diagnostic and therapeutic procedures performed in practice. The textbook includes new images and illustrations, as well as high-definition videos for use prior to procedures.

Nick Bexfield and Julia Riggs, editors of the new edition, said: "We have built upon the success of the previous editions by responding to the feedback received from the BSAVA readership, and hope this new guide helps to further increase the confidence and accuracy with which these procedures are performed."

Print copies are available in the BSAVA store, with a digital version in the BSAVA library.
