agent of pinworms
enterobius vermicularis
the symptoms of this disease are associated with migration and egg deposition of female worms on the perneum
enterobius vermicularis - pinworm
anal pruritis and irritability are common symtoms among children who have
enterobiasis (pinworm infection)
The Scotch Tape prep is used to diagnose
Enterobiasis (pinworm infection)
how is enterobius vermicularis transmitted
infection follows ingestion of embyonated eggs
pyrantel pamoate is an over the counter drug used against
helminth or worm infections
mebendazole and albendazole
antihelminth drugs
ascariasis
roundworm infection
enterobiasis
pinworm infection
the giant roundworm of man
ascaris lumbricoides
how is ascariasis diagnosed
from a stool sample - eggs can be found within the stool - eggs are the infective stage
the females are bigger than the males and they can migrate to several other organs in the body and cause symptoms
ascaris lumbricoides: giant roundworm
the larvae undergo a period of development in the lungs and can cause pneumonia and even be coughed up and re-swallowed
ascaris lumbricoides: giant roundworm
agents of hookworm infections
Ancylostoma duodenale and Necator americanus
how are hookworms transmitted
infective larvae penetrate the exposed skin, usually the foot
these worms feed on erythrocytes and can lead to hypochromic microcytic anemia
Hookworms: Ancylostoma duodenale and Necator americanus
typically in worm infections the eggs the infectious stage, however in this disease the larvae are infectious
Necatoriasis : hookworm
Trichuriasis
whipworm
trichuris trichiura
causative agent of whipworm infection
these worms infect the large intestine can be founded threaded or sewn into the mucosa of the cecum and appendix
whipworms: trichuris trichiura
this disease can be acquired by ingesting raw or insufficently cooked meat, mainly pork, containing encysted larvae
trichinosis
causative agent of trichinosis
trichinella spiralis
larvae enter the bloodstream and are carried to all parts of the body and encyst in striated muscle
trichinosis
eosinophilia commonly occurs due to
allergic reactions or some type of parasitic infection
the symptoms of this worm disease are muscle muscle pain, weakness, fever, and eosinophila
trichinosis
this disease can be acquired by ingesting raw or insufficently cooked meat, mainly pork, containing encysted larvae
trichinosis
causative agent of trichinosis
trichinella spiralis
larvae enter the bloodstream and are carried to all parts of the body and encyst in striated muscle
trichinosis
eosinophilia commonly occurs due to
allergic reactions or some type of parasitic infection
the symptoms of this worm disease are muscle muscle pain, weakness, fever, and eosinophila
trichinosis
the only human nematode infection in which larvae rather than the eggs are passed in the feces
strongyloides
may persist for many years due to autoinfection by larvae which transform to he filariform stage
strongyloidiasis
Toxocara canis and toxocara cati
agents of visceral larva migrans: dog and cat roundworms
Ancylostoma caninum and ancylostoma brasiliense
cutaneous larva migrans: dog and cat hookworms
larvae of dog and cat hookworms cause a dermitis in man called "creeping eruption"
cutaneous larva migrans (ancylostoma caninum, ancylostoma brasiliense)
the only human nematode infection in which larvae rather than the eggs are passed in the feces
strongyloides
may persist for many years due to autoinfection by larvae which transform to he filariform stage
strongyloidiasis
Toxocara canis and toxocara cati
agents of visceral larva migrans: dog and cat roundworms
Ancylostoma caninum and ancylostoma brasiliense
cutaneous larva migrans: dog and cat hookworms
larvae of dog and cat hookworms cause a dermitis in man called "creeping eruption"
cutaneous larva migrans (ancylostoma caninum, ancylostoma brasiliense)
cestoda
intestinal tapeworms
neurocysticerosis is associated with what species of tapeworm
Taenia solium -> pork tapeworm infection
taeniasis is to adult tapeworms in the intestine as cysticercosis is to...
larval tapeworms in the tissues
Taenia saginata
beef tapeworm infection
echinococcus granulosus
hydatid disease - larvae becomes encysted in various organs
the symptoms of this disease depend upon the location of cysts, also the release of fluid from the cysts into the surrounding tissues may caue anaphylaxis
Hydatidosis caused by Echinococcus granulosus
filariasis is the causative agent of
elephantiasis
Wuchereria bancrofti and brugia malayi are agents of Filariasis which are nematode infections that reside in
lymphatics
man is infected with Wuchereria (Filariasis) through
the bite of a female mosquito harbouring larvae
flukes
trematodes
a blood fluke disease in which flukes live in the veins of humans
schistosomiasis
Eggs are diagnostic they have lateral spines, snails are a critical part of their life cycle
Schistosomas
liver fluke disease commonly seen in vietnam veterans
clonorchiasis
a trematode disease of the bile ducts, can result in cirrhosis of the liver and carcinoma of the biliary tract
Clonorchiasis
cholangiocarcinoma associated with
Clonorchis sinensis
Paragonimiasis
lung fluke disease
Infection of this fluke occurs following ingestion of raw or rare flesh of crabs or crayfish containing mature larvae (metacercaria)
Paragonimus westermani
