Rabies Vaccination Campaign

Rabies, a deadly viral infection, is a threat to human communities, domestic dogs and the survival of many important species, including the endangered African wild dog. In Africa, most human cases of rabies are transmitted from domestic dogs instead of wild animals such as bats or raccoons. Unfortunately, children are most commonly infected.

Welcome to the Serengeti!

It’s my very first time to Africa, and my introduction to the wonders of Tanzania and Serengeti National Park has been simply amazing! As a veterinarian passionate about conservation medicine, it has been a treat to see more than 80 native mammals and birds in a few short hours in the Serengeti.

Siku ya Chanjwa! (Vaccination Day!)

Earlier in the season we joined forces with the Serengeti Health Initiative team to vaccinate dogs for rabies, distemper and parvovirus in Nangale village. The line was long, the sun was hot and there were lots of nervous puppies around. By the end of the day we vaccinated 350 dogs!

Sensa ya Watu na Mbwa (Human and Dog Census)

“Sasa, hi ni GPS…kama simu.” (Now, this is a GPS…kind of like a cell phone.) Chunde is explaining to the village leaders we’re working with as part of my domestic-dog demography research what a GPS unit is and how to use it.

Meals in the Field

My last post inspired a reader to ask what I eat while I’m in the field. Excellent question! While in Tanzania, I try to eat as much of the amazing fresh fruit as possible, if it’s available. Typically during this time of year (the dry season), there isn’t much of a fruit selection in the villages other than some bananas and tomatoes.

Back to Buyubi!

My field assistant, Chunde Bigambo, and I are back in Buyubi Village, a control village (a village where dogs are not vaccinated). We’re tracking all the dogs we marked here last year by visiting our study households and checking all dogs for ear tattoos and microchips.

We need to be able to identify each dog individually because many dogs not only look similar, they also have the same name!

Nimerudi! (I Have Returned!)

Here we go again! I’m back in Tanzania gearing up for my second field season studying free-roaming domestic dog population dynamics west of Serengeti National Park. I’m excited to see how all my study dogs are doing as well as reconnect with all my village friends.

This year I am revisiting the same households I collected data in last year. In 2010, I marked more than 800 dogs with ear tattoos and microchips so I can follow their life histories (life expectancy, survivorship and reproductive rates) for four years.

A Grim Reminder

I recently experienced a sad reminder of the importance of the Serengeti Health Initiative. On a drive out of the Serengeti, whilst passing through the Ngorongoro Conservation Area (NCA), I discovered a spotted hyena lying out in the midday sun having convulsions by the side of the road. It passed away soon after. Through the prompt action of the NCA veterinary team, samples were taken that have since tested positive for the rabies virus.

Nangale Vaccination Day

The road to Nangale village was filled with people walking their dogs, tugging uncertain puppies along on palm fiber leashes. If this were the bike path along Lake Shore Drive, this wouldn’t be so surprising. However, I was in Tanzania studying free-ranging domestic dogs that typically don’t get daily walks—they receive plenty of exercise herding, guarding livestock and protecting their households.

Mvua Atakuja (Rain is Coming)

I was in Nangale village at the start of rainy season, continuing to mark dogs for my dog demography study and there, was a sense of urgency in the air. “Mvua atakuja,” said Mayenga, the Nangale village chairman, as he surveyed the horizon. It was a clear cloudless day, and I had just stumbled upon an interesting spider as we were on our way to another household in search of dogs.
