What is the common name for the intestinal nematodes transmitted through contaminated
soil, including Ascaris lumbricoides, Trichuris trichuria, Ancylostoma duodenale, and
Necator americanus?
C) Soil-transmitted Helminths (STHs)
What is the typical life cycle of the human whipworm (Trichuris trichiura)?
Eggs are passed in the feces, embryonate in the soil, and become infective larvae.
After ingestion by a host, the larvae mature into adult worms in the large intestine.
What characteristic feature is associated with the feeding apparatus of Ancylostoma
duodenale?
Hook-like teeth
What is the primary purpose of the Kato-Katz technique (K-K), recommended by the
World Health Organization (WHO), in diagnosing and quantifying infections in endemic
localities?
Indirect estimation of worm burden through the number of eggs per gram of stool
(epg).
the primary route of transmission for Ascaris lumbricoides?
Fecal-Oral Route
Giant intestinal roundworm of man
Ascaris lumibricoides
Human hookworms
Ancylostoma duodenale and Necator americanus
Human whipworm
Trichuris trichuria,
nfant’s ingestion of mother’s milk
Translactational
Technique used to diagnose STHs
Kato-Katz
the typical duration of treatment for Ascaris lumbricoides infections.
. 1-3 days
of contaminated soil in unwashed hands either playing for children or working for
adults.
Ingestion
has a mouth with no teeth but with four chitinous cutting plates, two each on the
ventral and dorsal surfaces.
N. americanus
It is a study of parasites their hosts, and the relationship between them.
Parasitology
An organism that lives on or inside the body of its hosts from which they deserve
food and shelter.
Parasite
Trichuriasis is transmitted primarily through the ______?
Fecal-Oral Route
The name comes from the worm’s whip-like shape.
Trichuris Trichiura
An organism where the parasite lives, feeds, and obtains shelter from and is
therefore disadvantaged in the associations.
Hosts
Definitive Host is the adult stage that releases the eggs. t or f
