Bancroftian Filariasis Quiz

The size range of the Bancrofti parasite is 200-280 μm long.

The Bancrofti parasite has a sheath present.

Bancrofti has two distinct nuclei in the tip of its tail.

Bancrofti and Malayi are endemic in Southeast Asia and specific regions of the Pacific.

Humans are the primary hosts, but B.malayi can also infect felines and monkeys.

Infections with B.malayi are often asymptomatic, with symptoms taking months to develop.

Fevers may take months to years to develop after initial infection with B.malayi.

Successful resolution of symptoms in patients after treatment with DEC (Diethylcarbamazine).

Adult O.volvulus worms range from 150-500 mm long.

Microfilariae of O.volvulus do not possess a sheath.

Nuclei in O.volvulus extend almost to the tail tip, not quite reaching it.

O.volvulus is primarily found in equatorial Africa and Central America.

Simulium blackfly is the known vector for O.volvulus.

Infection usually leads to River Blindness (Onchocerciasis).

Diagnosis involves Giemsa-stained tissue biopsies known as skin snips.

Adult females can measure up to 500 mm long and coil in nodules.

An infection caused by the parasitic worm Loa loa.

Specimen of choice for recovering L. loa microfilariae.

Localized subcutaneous edema due to L. loa migration.

L. loa shows heightened activity between 10:15 AM and 2:15 PM.

Increased eosinophils in the blood, often linked with parasitic infections.

Medication of choice for treating L. loa infections.

Preferred method to extract adult L. loa worms from the body.

A method used to recover microfilariae from blood samples.

Oncosphere migrates via blood to animal tissue, developing into cysticercus.

The larval stage of the tapeworm that infects human hosts through consumption of infected meat.

Taenia saginata is found in areas where beef is commonly eaten and sanitation is poor.

Taenia solium is found worldwide, often linked to pork consumption.

Infected individuals may experience diarrhea, abdominal pain, appetite change, and slight weight loss.

Many infected with Taenia species remain asymptomatic and show no signs of illness.

The prognosis for most Taenia infections is usually good.

Also known as the rat tapeworm, it causes Hymenolepiasis or rat tapeworm disease.

An embryo with six hooked structures, typical in tapeworms like Hymenolepis diminuta.

A colorless capsule surrounding the hexacanth embryo in the eggs of some tapeworms.

The head region of a tapeworm that typically contains suckers or hooks for attachment.

Average size 55 by 85 μm, three pairs of hooklets, polar thickenings present.

Infection occurs after ingesting raw or undercooked beef or pork containing cysticercus larvae.

A larval form of Taenia with a scolex and fluid-filled bladder.

The scolex attaches to the intestinal mucosa after ingestion.

A medication effective against adult Taenia worms, except with CNS involvement.

Important measures include sanitation, proper cooking, and prompt treatment.

Infected individuals may be asymptomatic or experience nausea, pain, and weight loss.

Distinguishing between these involves egg morphology and uterine branch count.

Distinct from T. saginata and T. solium, can host multiple adult worms.
