Larviparous nematode. Hello My YouTube Viewers !! Challenge yourself to not only identify a hookworm egg by genus alone, but by species. Faecal egg counts (FEC) are routinely used to aid diagnosis of nematode infestations but have certain limitations: Faecal egg counts may not accurately indicate the nematode population present in the gastrointestinal tract at that time. Eggs of the different helminths were identified on the basis of morphological appearance and size of eggs according to the literature (Foreit, 1999). Nematodes, commonly known as roundworms, are a group of worms that make up the phylum Nematoda. The L3 were then stained Some 80,000 species are described in the literature; possibly a million exist.

The unsegmented yolk appears as a compact mass in the centre. of their life cycle. Since species identification cannot be determined from evaluation of Nematode eggs, researchers in the 1970's developed a technique in which they hatched the fecal eggs and identified the species based on morphological differences of L3 larvae. Thick shell that is coarsely pitted with prominent bosses or knobs on the outer surface. 2016;166:164–172.
