Paragonimus westermani Eggs: Microscopic Morphology

Thu, 29 May 2025 11:00:01 +0300

🔬 Paragonimus spp. eggs in unstained wet mounts.

Paragonimus westermani eggs are 80-120 µm long and 45-70 µm wide. They are yellowish-brown, ovoid or elongated, with a thick shell, often asymmetrical, with one slightly flattened end. The operculum is clearly visible at the larger end. The opposite (abopercular) end is thickened. The eggs are unembryonated when passed in sputum or feces.

Intestinal Schistosomiasis: Microscopic Diagnosis of Schistosoma mansoni Eggs

Sun, 23 Feb 2025 16:00:01 +0300

🐍Answer to the parasitology video quiz Schistosoma mansoni. Intestinal schistosomiasis. Microscopic examination revealed an oval egg with a “lateral spine”.

Sometimes it may be necessary to tap the coverslip to move the eggs; the lateral spine may not be visible if the egg is turned on its side.

Sat, 15 Feb 2025 12:00:00 +0300

🔬 Clonorchis sinensis Eggs They are small, measuring 27 to 35 µm by 11–20 µm, and have an oval shape with a convex operculum that rests on visible “shoulders.” A small projection or hook-like protrusion is often visible at the opposite (anopercular) end. A miracidium may be visible inside the egg. C. sinensis eggs are morphologically very similar to Opisthorchis spp.
