Which of the following is an incorrect match between organism and diagnostic procedure?

The association of Echinococcus granulosus with a routine ova and parasite examination is incorrect because this diagnostic approach is typically not sufficient for the detection of this organism. Echinococcus granulosus is a tapeworm that causes cystic echinococcosis (hydatid disease) in humans. To identify this parasite, more specific imaging studies, such as ultrasound or CT scans, are often employed to visualize the hydatid cysts it forms in the organs, rather than relying solely on the ova and parasites examination that is primarily effective for detecting more common intestinal parasites.

Other matches provided in the choices represent correct diagnostic associations. For instance, Onchocerca volvulus is accurately identified through examination of skin snips to detect larval forms known as microfilariae, while Cryptosporidium can be effectively visualized using modified acid-fast staining techniques due to its resistant oocysts. Schistosoma haematobium can be diagnosed by examining urine sediment to find its eggs, as this parasite typically affects the urinary tract.
