Common cestode infections
Cards in this deck (33)
- 1Taenia saginata is more commonly known as?Beef tapeworm
- 2Taenia solium is more commonly known as?Pig tapeworm
- 3Echinococcus multilocularis is more commonly known as?Small foxtapeworm
- 4Echinococcus granulosus is more commonly known as?hyatid tapeworm
- 5what species are the only definitive host of Taenia?humans
- 6What is meant by the term definitive host?the host in which sexual reproduction of the parasite takes place
- 7Infection with taenia occurs by?ingestion of raw/ undercooked meat
- 8Adult taenia worms live in the ?Small intestine
- 9Taenia attach to the small intestine via their?Scolex
- 10What is an important diagnostic feature which we can use to distinguish between different Taenia'sThe rosetellum
- 11Give some rare symptoms of taenia?obstruction,
diarrhoea
hunger pains
weight loss
appendicitis
discomfort
proglottids crawling from anus - 12Give a definition of taeniasisHumans get infected by ingesting raw or undercooked meat containing cystercerci, symptoms are moderate
- 13Give a definition of cycticercosishumans ingest eggs or gravid proglottids of taenia solium,severe symptoms
- 14How can we treat cycsticercosis/ taeniasis?Praziquantel/ niclosamide
- 15What is the mechanism of action of niclosamide?prevents glucose uptake and oxidative phosphorylation, so worms cannot feed, they die and starve as glucose cannot enter the tissues
- 16What is the mechanism of action of praziquantel?causes the flatworm to lose its ability to resists digestion so the tapeworm becomes degraded in the gut.
- 17Why is niclosamide not the drug of choice?Has side effects
- 18Give 2 examples of zoonotic cestode infectionsEchinococcus mutiocularis (alveolar)
echinococcus granulosus (cystic) - 19Give a definition of a zoonotic infectionwhen a pathogen which is usually found in animals infects humans
- 20Give 3 reasons why zoonotic cestode infections are important?animal reservoir- animals are more widespread more difficult to eradicate
pathology more severe- we dont have any antibodies agains them
can be transmitted via pets and live stock - 21Cystic echinococcus is caused by.....granulosus
- 22Alveolar echinococcus is caused by...multilocularis
- 23Give some symptoms associated with Cystic echinococcuscough
abdominal pain
anaphylaxis and allergic reactions if cysts rupture - 24Give 2 ways in which we can diagnose Cystic echinococcus infection?Serology- look at antibodies
Medical imaging- brain scan, MRI - 25What is the problem with the diagnostic techniques used to diagnose Cystic echinococcusThey wont detect a fresh infection, only an infection that has been present for some time
- 26How long does it take for symptoms of alveolar echinococcus to show?5-15 years
- 27Give some symptoms associated with alveolar echinococcusweight loss
abdominal pain
hepatic failure
malaise - 28The growth of alveolar echinococcus is similar to a...Metastatic cancer
- 29How can alveolar echinococcus be transmitted to dogs?By eating infected sheep livers
- 30How can alveolar echinococcus be transmitted to humans?foecal oral route
- 31How can we treat cystic echinococcus?Albendazole
Mebendazole
Praziquantel - 32What are the contraindications in treating cystic echinococcus?large cycts at risk of rupture
inactive/ calcified cysts
early pregnancy - 33How can we treat alveolar ecinococcosis?surgery,
albendazole
chemotherapy
