A keeper on the Oklahoma Metropolis Zoo someday seen that Eko, a Sumatran tiger, stored rubbing his face on the facet of the fence, breaking all his whiskers.
A staff began treating the tiger with antihistamines, however he continued to rub his face. Ultimately, the employees partnered with a veterinary dermatologist who got here out and carried out pores and skin allergy testing to see what Eko was reacting to.
Whereas allergy symptoms in domesticated animals like canines, cats, horses, and a few birds are widespread, specialists say there are few documented instances of allergy symptoms within the wild. It’s not clear whether or not that’s as a result of wild animals are much less prone to allergy symptoms than domesticated animals or whether or not scientists haven’t been capable of observe wild animals intently for signs of allergy symptoms.
“It’s not as widespread as you’d see in home canines and cats, but it surely definitely does occur,” says Dr. Jennifer D’Agostino, DVM, DACZM, and chief animal program officer on the Oklahoma Metropolis Zoo. “Now that we now have extra superior drugs and information, I feel it’s in all probability being identified greater than perhaps it was previously.”
Allergic reactions for Zoo Animals
A number of theories why animals don’t usually have allergy symptoms within the wild reference that animals are uncovered to extra environmental microbes and parasites and should develop stronger immune techniques than animals which have been domesticated. Pure choice may come into play: If animals have extreme allergy symptoms, they won’t survive lengthy sufficient to breed.
That stated, wild animals that reside in zoos do get identified with allergy symptoms.
Eko obtained common injections to desensitize him to the allergens, with the promise of his favourite deal with.
“He did nonetheless need to have some antihistamines right here or there if he had a flare-up, however the allergen remedy helped him out tremendously,” D’Agostino says. “His hair grew again, his whiskers grew again, and he wasn’t rubbing his face anymore.” Eko was finally transferred to the Akron Zoo, the place he’s doing effectively.
D’Agostino attributed Eko’s allergy symptoms partly to his location. “Oklahoma has a number of allergens,” she says. “Even for the people who dwell in Oklahoma, it’s a really allergenic state.”
As well as, some wild animals in zoos have been bred underneath human care and over time, may grow to be prone to allergy symptoms by genetic drift. Lastly, the animals in zoos are watched intently, so signs of sickness grow to be obvious shortly.
“Our keepers are very attuned,” D’Agostino says. “They know these animals extremely effectively.”

The Atmosphere and Treating Allergic reactions
D’Agostino sees allergy symptoms extra usually in carnivores and in birds than different species and thinks atmosphere performs an vital position.
“They’ve advanced of their specific area of the world, they usually could not have come into contact with a selected [allergen], so perhaps their immune system just isn’t used to that,” she says. “They’re uncovered to grasses and vegetation that they might by no means come throughout of their native habitat.”
D’Agostino can be presently overseeing remedy for the allergy symptoms of a jaguar named Zia and two elephants. Zia was licking herself and creating hotspots from itchiness. The veterinary dermatologist decided that Zia was allergic to fleas and mosquitos and put her on two totally different flea medicines, allergy pictures, and sprayed her atmosphere for fleas.
The Oklahoma Metropolis Zoo additionally had two Asian elephants on allergy remedy for pollen and grasses: Kairavi and her aunt, Chandra. Due to their thick pores and skin, testing for pores and skin allergy symptoms was not potential, however the zoo carried out blood allergy checks. Once they retested, solely Kairavi was nonetheless reactive, and he or she continues to be on oral allergy remedy.
Dr. Kadie Anderson, DVM, the affiliate veterinarian at Level Defiance Zoo & Aquarium in Tacoma, Washington, can be treating 4 animals with allergy symptoms: two beavers, a polar bear, and a Nigerian dwarf goat. She thinks a part of the explanation instances within the wild are uncommon is as a result of scientists typically aren’t observing these animals.
“The allergy symptoms might not be apparent in an animal that’s dwelling out within the wild,” Anderson says. “Now we have our employees biologists actually intently watching and dealing with these animals.”
Signs of allergy symptoms she sees embody itchiness, runny eyes, crusty pores and skin, and recurrent ear infections. She’s presently treating a beaver on the zoo named Nutmeg and her companion, Walnut and overseeing the care of Astra, a polar bear that was displaying itchiness. The veterinary dermatologists discovered that she was allergic to bushes, leaves, yeast, mites, bugs, and canines. Astra’s keepers are presently coaching her to simply accept administration of immunotherapy underneath her tongue.
Different animals which have been handled for allergy symptoms in zoos embody black leopards and pteropid bats, in line with research within the Journal of Zoo and Wildlife Medication.
“As our local weather adjustments and because the climate adjustments, I feel we’re going to see vegetation probably flower for longer durations of time, or they is perhaps releasing pollen for lengthy durations of time,” Anderson says.
