This section is simple yet vital in maintaining the well-being of horses by detecting external and internal parasites or parasitic ova in the fecal or skin scraping samples. Internal parasites being one of the common health concerns among horses wherein intestinal parasite like ascarids, large and small strongyles and tapeworms may cause weight loss, anemia, diarrhea and colic. Direct mount microscopy, fecal flotation, fecal sedimentation for lung worms, fecal sand test, Knott’s test for equine microfilaria, fecal worm egg reduction test, Baermann’s test for nematode larvae and quantitation of egg parasites in the stool using McMaster fecal egg count are the routine tests at the laboratory. Peripheral blood smears for suspected equine piroplasmosis and cryptosporidiosis are examined using staining and microscopy. Skin scraping KOH test for checking external parasites and dermatophytes is available. Fecal occult blood test and nematode larvae culture test are in line to be added to the laboratory portfolio.
