Ferret quarantine exam

2 female, a few weeks old, ferrets had no abnormalities. Performed: rectal swab and blood collection (CBC, Chem, Heart worm).

Elk, antlers

The elk antlers to be treated tomorrow, as they are growing toward the orbit!

Wallaroo, quarantine exam

1. examination: observation, palpation
2. radiographs: whole body, especially jaw for detail
3. blood: CBC, Chemistry
4. rectal swab

Findings & treatment
1. left torn/bent off (=avulsed) toe nail :
a. removed by tearing it off, clipped, cleaned, left open,
b. cultured fluid from wound,
c. antibiotic (enrofloxacin inj, s.i.d., continued with trimethoprim sulfadiazine),
d. anti-inflammatory : metacam
2. enlarged cardiac silhouette :

Boa, lethargy and mass examination

History: slightly week, partly paralyzed, mass
Finding: 28cm from head there is spinal osteomyelitis, and a rotated rib has lead to an indention. No mass
Tx: vit B to stimulate appetite, flagyl for potential flagellates. Prognosis: disease is not curable. Should eventually be euthanised. Not to be adopted.

On my few days off…..

I try to see the rest of the city and its surroundings! So I got sunburned for the first time last weekend at the beach! These local fishing vessels is were a few Norwegians have become large men!

Axolatls, quarantine examination

1. radiographs: the least amount of water gives the best image as their body density is similar to that of water.
2. observation: microscopic evaluation of their exterior.

Ocelat, endoscopic, ultrasound examination, specialist ER clinic visit

Endoscopic findings:
1. gastro-esophageal iatrogenic intusseception
2. stomach and colon are fine
Ultrasound findings
1. slightly enlarged liver: portal vein: normal bl.pres
2. slightly enlarged mesogastric lymphnodes : ca. 4mm
3. abdominal fluid : aspirated sample was colored weak yellow
4. GI: normal

This weekend off became completely different than planned, as one of the zoos elephants was to be inseminated. To entire procedure turned out to be a longer than expected as the follicle ovulated almost a day later than expected, and there are only 3 elephant bulls in the US (1 in Canada) that have the ability to serve as sperm donors. So in order to accomplish this, an expert (sperm collector) from Florida was flown in, along with 2 German reproductive specialists. All seemed well until our first problem came up: the Department had sent as the wrong permit. They had allowed us to bring sperm from the wrong specie, from a large sea mammal. All thanks due to government cut backs. Maybe they (the government) can wait, but the follicle certainly will not. Then the sample from the first backup bull in the US couldn’t arrive back in time. The third bull delivered some OK samples, but the swimmers kept dieing in transport. So until the elephant is checked by ultrasound in a few months time, who knows how successful this procedure became.
So all in all, I got to go on a roadtrip t to see the sperm collection, and I got to see plenty of insemination procedures here at the zoo. Elephants are wonderful large animals, but their gestation period is the longest of all animals, 22 months. In return, they are over 10 feet tall, and weigh from 8000 -13000 pounds. (female is smaller). I can show the complete picture series of everything later, as this would take way to much space on this site.

Thrush, nematode

Heres the end of the nematode I found in the birds cecum!

Cattle, Lice (bovicola bovis)

I have now learned how hard it can be to get rid of lice. This was me before the job was done. 3 hours later, the barn was clean, and I wasn't!

Black headed laughing thrush, necropsy


4 of the 5 Black Throated Laughing Thrushes have died due tonematode infections. They die within 6 hours of any clinical signs. We have tried all sorts of treatment once they have been caught, but this takes time as they have a super-sized aviary.

Patas Monkey, ocular, micro surgery

One of our monkeys had her left ocular lens emulsified and aspirated. A veterinarian ophthalmologist did the procedure.
Complete radiographs were taken before the 20minute procedure was performed, to make sure there were no thoracic alterations that would decrease the importance of the ocular disease.

Hippo, skin, wound/abscess, visual examination

There are now two hippos with skin lesions. There placement, size, and stage differ. See images for visual impression. There are also systemic signs: decreased appetite and depression according to the keepers.
A skin flake was collected for analysis. More research has to be done, so until more is known, we are attempting to give them amoxicillin by oral bolus. As this isn't always successful, we are also ordering a liquid solution. The difficulty is making the proper flavor, and making them drink/eat 600ml each day. This isn’t easy. If you were a hippo, would you eat 3 tennis balls coated with some fruit flavor, knowing that the rest tastes bad?

River otter, health exam

I assisted a sea otter’s health exam. They have scent glands on their distal hindlimbs!
