“Avian malaria can be carried by all wild birds and although is not infectious to us or the wild birds, penguins have never had to build an immunity to this as they live on or near the sea where the insects that carry the disease do not occur.“Avian malaria can be carried by all wild birds and although is not infectious to us or the wild birds, penguins have never had to build an immunity to this as they live on or near the sea where the insects that carry the disease do not occur.
“This summer at least two other collections have also contracted the pathogen, which is a protozoa living in the blood of its hosts and usually spread by mosquitoes or biting midges from the original host bird.”“This summer at least two other collections have also contracted the pathogen, which is a protozoa living in the blood of its hosts and usually spread by mosquitoes or biting midges from the original host bird.”
Danny Reynolds, the living collection manager at Exmoor Zoo, said: “The protozoan pathogen cannot be easily identified in the blood of the penguins and dies very quickly so it cannot be seen with blood samples.

“Unfortunately, all drugs given from pathological reports had no effect and it is now known that once the malaria is contracted even the anti-malarial drugs cannot help the infected bird but the drugs can stop other penguins from contracting the disease.“Unfortunately, all drugs given from pathological reports had no effect and it is now known that once the malaria is contracted even the anti-malarial drugs cannot help the infected bird but the drugs can stop other penguins from contracting the disease.

The zoo said it would consider whether to try to exhibit penguins again. Its statement added: “The disease may never strike again for another 25 years or more but could just as easily occur again next year – it all depends on what birds migrate through the avian malaria areas in Africa and if they visit Exmoor. If we do, then a lot of care will be given to any possible prophylactic treatments and stocks of the anti-malarial drugs will be available.”The zoo said it would consider whether to try to exhibit penguins again.

It concludes: “Perhaps this is the time to say goodbye to some of the individuals we have looked after (some for 23 years or more) – Buster, Newquay, Ludo, Percy, Lemmy, Truddle, Owlie, Blossom, Friendly and Arthur. They are being keenly missed especially by those keepers who have given significant years to their care over time.”It concludes: “Perhaps this is the time to say goodbye to some of the individuals we have looked after (some for 23 years or more) – Buster, Newquay, Ludo, Percy, Lemmy, Truddle, Owlie, Blossom, Friendly and Arthur.

Paul Caine said: “Had to read that many times before believing it, I’m absolutely stunned ... My daughter, when she was about two years old, bought a fluffy penguin from the zoo and called it Buster. She’s now 10 and still completely inseparable from her Buster.”Paul Caine said: “Had to read that many times before believing it, I’m absolutely stunned ...
