During the last 2 weeks, we have had 2 patients test positive for exposure to a parasite called Trypanosoma Cruzi. This parasite is carried in a specific bug called a Kissing Bug. Kissing Bugs have orange stripes on their body and long heads. The parasite is passed to dogs, and rarely cats, through the Kissing Bug's p**p. If the dog eats the bug, or has contact with the bug's p**p, the parasite enters the dogs body. The parasite, T. Cruzi, then travels to the dog's heart through the blood stream. Eventually, the dog develops right sided heart failure. There is currently no treatment for a T Cruzi infection, and a dog infected with T Cruzi will likely die from heart failure. They call that disease process, Chagas disease. One of my patients that tested positive was tested as a screening process for a clinical trial for a new drug at A&M. She has no symptoms of infection. This dog is very well cared for and lives in NE Austin. The 2nd dog was tested because I actually found 2 Kissing Bugs on my deck 3 weeks ago. I sent pictures to the Kissing Bug lab at A&M and they confirmed they were Kissing Bugs. I have sent the bugs to A&M for testing to see if they carry the parasite. They were dead, but as a precaution, I tested my daughters' 4 dogs as they have spent time on our property. 1 of my daughters' dogs has tested positive. That doesn't mean she was exposed here on our property, but it is a possibility. Most of the time we discover a dog is infected with T Cruzi and has Chagas after the heart disease develops, not before. So we are still looking at what the prognosis is for these 2 dogs. But I think it is very important that my clients know what a Kissing Bug is and keep an eye out for them. Here is a good webpage for more information and pictures of the bugs. The bugs I found were under a spider web ( THANK YOU spider). I never would have known they were there. If you find a kissing bug, don't touch it. Use a bag over your hand to collect it and put it in the freezer until it dies. I do recommend sending pictures to A&M for confirmation.
Texas A&M research on kissing bugs and chagas disease in the United States with the help of citizen scientists to uncover the distribution of different species of kissing bugs, their infection prevalence over time, and their interactions with host species.
