Pet ownership can change your life. A loving cat might bring out your compassionate side. Regular dog walks can help keep you more active. That's all well and good, but Trypanosoma brucei rhodesiense takes everything to the next level. This little parasitic protozoa can literally transform you into a different person.

Carried by the East African tsetse fly, a good infection of T. brucei rhodesiense can cause personality changes -- not in the touchy-feely sense, but in the clinical sense. Some people refer to the effects as East African sleeping sickness, choosing to focus on other symptoms, such as headache, skin rash, progressive confusion, irritability and eventual death if untreated.

But what kind of sensible pet owner focuses on the negatives? T. brucei rhodesiense offers you the rare chance to hold a dear friend so close that they're actually inside your central nervous system. Ready to transform your life? Just contact your local travel agent and ask about trips to rural East Africa.

Other selections: Too much of a wimp to let this ittle East African cutie change your life? Well, Naegleria fowleri can alter the way you perceive smells and Toxocariasis.
