Parasite from abandoned dog?

Question: We took in an emaciated blue heeler abandoned in the woods on the Big Island of Hawaii’i. I started getting 1x2 inch oval patterns of red dots on my arms and legs with 1/4' hairs sticking out at a 45 degree angle. They turned into deep oval wounds with white worms around the edges that I couldn't remove. Eventually I pooped out hundreds of creatures that looked like 2" long shrimp with long snouts. What could this be and did I get it from our dog?

response: Not looking for medical advice. Just asking if this is a parasite you have ever seen.Sent from Yahoo Mail on Android  On Sun, Apr 30, 2023 at 5:29 PM, Ask Extension<<personal data hidden>> wrote:

response: There are no obvious parasites that I can see in the photos that you have provided. It is unclear to me what images labeled A and C are though these look like a screenshot from a textbook.

response: Hi Alec,Thank you so much for your kind reply! This is dead serious, as 3 others are infested and Infectious Disease Specialists are baffled. I used screenshots because they use less memory and allow me to attach more pictures. I know its hard to see what is under the skin, except the bizarre pink parasite that is on a piece of toilet paper. If I could at least learn what phylum that creature is, that would be a good starting point. Here's a picture of the tail end of a dead worm I tried removing after taking Combantrin. It fell apart.The black pairs of suckers in picture 3 should be a clue. The last pictures are of things I pulled out of the wounds. The emaciated blue heeler we rescued from the woods seems fine now. Fat and happy, but still eats poop. This started right after we got her.Thanks, JohnSent from Yahoo Mail on Android  On Tue, May 2, 2023 at 6:50 AM, Ask Extension<<personal data hidden>> wrote:

response: The images remain too grainy/blurry for me to determine what is in the image, though nothing I see leads me to believe that I am looking at an insect or other parasite. I recommend that you provide your samples to a veterinarian (given the connection to your new dog) or to your physician. These folks can reach out to a parasitologist if needed to identify a parasite. Most organisms are best placed into 70% ethanol, though rubbing alcohol works also as a preservative and sterilant.  Sincerely,
