Hello again!
I wrote this blog post in a few stages, but
the main purpose is to summarize part of our week spent with Dr Ludwig Seifert, an
excellent wildlife vet who has worked in Uganda for more than 30 years. To give
a little background, we are staying in little student rooms on the Mweya
Peninsula in Queen Elizabeth National Park, which is home to many species of
wildlife. One memorable night this week we saw a leopard walking into the
trees, watched elephants strolling a few meters from our door and opened the
curtains to see a hippo munching some grass behind our rooms.
The first few days we spent time helping
out with a human disease screening project, and I wrote some of the following
paragraphs while I was waiting to enter patient data:
I am sitting in a warm room in the back
corner of a run-down medical clinic in Muhokya, where we have been since 8:00
this morning. There are scuffed yellow walls with HIV posters hung up with band
aids or masking tape, and a lineup of patient people waiting to receive an
ultrasound. Tara is standing behind Dr. Eberhard Zehyle as he runs the ultrasound
probe over a woman’s abdomen, Elad is taking notes while watching the
ultrasound screen, Katie is drinking water to stay hydrated in this stuffy
place, and Ilse and I are recording patient information. We switch back and
forth doing different things and I am on the job of initial patient
identification, which leaves a bit of time to write as there is a current back
up at the “long survey” station Ilse is running.
Here is the typical scene - everyone with a job to do
This guy was my buddy when I was taking a water break, but when he came to get tested, he was terrified! Our translator said he was screaming "I'm dying!!!" while getting his ultrasound

The purpose of today is to screen for
Hydatid disease, which is caused by a very interesting parasite called
Echinococcus. I have copied a picture from our parasitology notes, courtesy of
Dr. Polley at the University of Saskatchewan, to better explain why this is
such a cool parasite to study, especially in this part of the world. The main
route of human infection is through contact with eggs found in dog feces. Once
the eggs are ingested, the larvae move through the blood stream and can cause
cysts to form in various organs, but most commonly the liver. Humans act as an "incidental host" which means they do not transmit the disease back to dogs like the moose (or Hartebeast of Water Buffalo), but they are still susceptible to cyst formation. If the disease is
caught early it can be successfully treated with drugs, but later in its
course, it requires surgery. Due to the presence of lions, leopards, and other
carnivores in African countries like Uganda, some scientists speculate that
these species could also transmit this parasite to humans. In addition, there
are also many different herbivores including goats, buffalo, and countless types
of antelope which could take on the role of the “intermediate host”. Such zoonotic
diseases highlight the important relationship between human and animal health,
often referred to as “One Health”.
Here is Dr. Polley's life cycle- I added a few pictures to the original
The people Katie and I collected initial information from while they patiently waited for their scan
We had a lot of fun - the women were very patient with our broken Ryankole (their local language)
It was a long day for these women, and we also made a new little friend
So after 3 days helping out with the ultrasound clinic, we saw about 400 patients and around 10 positives for Hydatid Disease. The doctors carrying out the study hope to organize treatment for these patients, and hopefully we were able to educate some people about how to break the disease cycle. Overall, it was a worthwhile experience and I definitely learned a lot about the human-animal health connection in the people living in Queen. Our last day spent with Dr. Seifert was very exciting, but I think I will let Tara tell you about our experience with “the lion man”.
Cheers!

Ps. (This is a VERY critical paragraph for
all our readers) I am starting to get concerned about Elad. Whenever I leave my
computer open he writes flattering blog articles about himself. Although, he
definitely did impress me today. He’s basically my mentor. I’m not sure what I
would do without him. I’d be completely lost! Yep, he sure is the best.
Here we all are with Dr. Zehyle at the end of our 3 days of work
Lastly, I could not help putting up this picture I snapped while driving out to our work - we had a sort of a stand off with this guy. He did NOT want to leave the road, so he shook his ears at us and we had to back up the land rover for a km or so until he became more interested in the Acacia trees.
