Hi, I am hoping that you can give me some insight into this matter. My husband has had diarrhea for about a week now. He went to the doctor, and we are waiting for results from his stool sample. This morning, he had an accident in his pants, and we found this worm that doesn’t resemble any of the more common intestinal parasites. I searched the internet, and found a post from Feb. 2013 titled “Can Centipedes really crawl up your butt??” The culprit resembles the picture in the post, so I am wondering what the final findings were. Thanks.

Dear concerned wife,
We invested much research into the posting you cited: Can Centipedes really crawl up your butt?? What we find troubling about your submission is that your Centipede does not look like a Soil Centipede, the group that was the subject of all our research as well as other strange reports we have received including Soil Centipede presumably passed during bowel movement and Soil Centipede found in Bath Water. BugGuide also has a submission of a Soil Centipede found in a human stool sample. Soil Centipedes are described on BugGuide as being: “Slender, rather sluggish eyeless centipedes that have 27 to 191 pairs (the number of leg pairs is always odd) of legs and 14-segmented antennae. They burrow in the substrate in a manner similar to earthworms, by elongating and contracting their bodies.” If our calculations are correct, your Centipede has fewer than 21 pairs of legs, so it is NOT a Soil Centipede. Additionally, your Centipede does not appear like it has been in a human gastrointestinal tract. Your Centipede appears like it might be in the genus Cryptops, based on this imaged of Crytops hortensis which is posted to BugGuide and appears to have the same number of legs as your individual. We also have a posting on our site of a Tiger Centipede found in a young lady’s panties, and it was definitely NOT a parasite. We suspect it just sought out a warm dark place, which is what we are inclined to believe regarding the Centipede you found. We would urge you to keep the specimen and take it to the doctor conducting the stool sample, but again, we are inclined to believe the two instances are a coincidence and that your husband’s diarrhea is not related to the discovery of the Centipede in his dirtied pants. Please keep us posted if there are additional developments or questions.
