❓ A question from a subscriber. In what cases can pinworm eggs with immobile larvae be found in a perianal swab? Are these immature or could it be during treatment?
✅ This is a non-native preparation; the eggs in it are immobile, but the larva inside the egg does not move. In all the swabs I have seen, and there have been many, the larvae in the eggs were viable, i.e., movement was observed. I am particularly interested in what more experienced colleagues will answer, as I could not find information online.
✅ The question is kindly posed by laboratory assistant Svetlana Sergeevna, Raduzhny City Hospital.
