The fecal egg count reduction test was suggested in the World Association for the Advancement of Veterinary Parasitology guideline for estimating the reduction in fecal egg counts and its corresponding confidence interval. [1] The results of this test can be used to determine the anthelmintic resistance status of the animals.
Faecal egg count is widely used to identify and select animals that are relatively resistant to nematode infection. [ 22 ] [ 23 ] [ 24 ] Selection is most advanced in Australia and New Zealand where the dominant nematodes are Haemonchus contortus or a mixture of T. circumcincta and Trichostrongylus colubriformis .
The direct counting of nematode eggs in feces is the method of choice for yearling animals, whereas in adult animals it may yield high variability due to a cow's immunity and low egg output. [41] Other biochemical methods have been developed to help more accurately diagnose O. ostertagi parasitism. These include the determination of specific ...
Treating a horse with regular dewormer when they have the worms inside of them may cause the worms to migrate all at once, causing rupture of the intestines and lead to death. [11] Recommendations for deworming horses include performing fecal egg counts to determine what kind of protection each individual horse requires and alternating products ...
Eggs per gram (eggs/g) is a laboratory test that determines the number of eggs per gram of feces in patients suspected of having a parasitological infection, such as schistosomiasis. [ 1 ] Measuring the number of eggs per gram is the primary diagnostic method for schistosomiasis, as opposed to a blood test .
Mature horses appear to develop a certain degree of resistance to this parasite, but it is a concern for younger horses up to about two years old. [4] P. equorum is one of the few parasites where a natural immunity develops in the host. [3] However, when an infection is found in an adult horse, both the worm and egg counts are substantially low ...
After the eggs have hatched in the feces, the larvae are ingested by the maggots of various flies that lay their eggs in the feces (such as Stomoxys (the stable fly) or Musca (the house fly). The nematode larvae develop within the maggot for about one week (depending upon ambient temperature), as the maggots mature into the imago (adult) fly .
The game of conkers is played with a horse-chestnut seed with a string threaded through it. Conkers is a traditional children's game in Great Britain and Ireland played using the seeds of horse chestnut trees—the name 'conker' is also applied to the seed and to the tree itself. The game is played by two players, each with a conker threaded ...
