An identifying characteristic of the eggs of Schistosoma species is the
presence of: - -Lateral or Terminal Spine
-A patient presents with vague abdominal pains and a microcytic
hypochromic anemia. A possible causative parasite is: - -Necator
Americans or Ancylostoma duodenale
-Enterobius vermicularis infection is usually diagnosed by finding eggs
from: - -Perianal cellophane tape test
-Schistosoma cercariae enter the human body: - -By direct skin
penetration
-The human condition resulting from ingestion of the immature larval
form of Diphyllobothrium latum is called: - -Sparganosis
-Packets of tapeworm eggs encapsulated in a single membrane were
recovered in feces. This parasite is: - -Dipylidium caninum
-The three most encountered species of human blood flukes have as
intermediate host: - -Snails
-Which of the Platyhelminthes infects humans by skin penetration and
has an association with bladder cancer? - -Schistosoma haematobium
-The eggs of which two species are infective to humans if ingested,
resulting in larval stages and pathology in the host's tissues? - -
Echinococcus granulosus and Taenia solium
-In which of the following sets of nematodes can each organism cause a
pneumonia-like syndrome (Loeffler's syndrome) in a person exposed to
heavy infection with any of three parasites? - -Necator americanus,
Ascaris lumbricoides, Strongyloides stercoralis
-A trematode whose egg has NO operculum is: - -The Blood Flukes
-One of the most serious complications of infection with Ascaris
lumbricoides is: - -Intestinal obstruction or rupture due to migrating
adults (bolus)
-Unsheathed microfilariae are characteristic of: - -Onchocerca volvulus
OR Mansonella ozzardi
, -An immunosuppressed patient is susceptible to auto reinfection with
which one of the following nematodes? - -Strongyloides stercoralis
-Eggs from Hymenolenis nana can be differentiated from hymenolepis
diminuta in that only the eggs of H. nana have: - -Polar filaments
-Infections due to migration and death of Loa loa microfilariae may
cause localized subcutaneous edema know as: - -Calabar swellings
-Microfilariae of Wuchereria bancrofti are located in the: - -Blood
-Int he Diphyllobothrium latum life cycle, the infective stage for humans
is: - -Plerocercoid
-A child who plays in dirt contaminated with human and pet feces is
susceptible to which of the following parasites? - -Anything that is shed
in feces, which is a lot of things. So basically NOT the fliariae, Trichinella
spiralis, or Dracunculus medinensis
-Mature eggs of an adult tapeworm accumulate in the: - -Gravid
proglottid
-You have decided to move to the Great Lakes area of the United States
to become a sheepherder. You will be a hermit, enjoying a completely
self-sustained life by the edge of a lake with your sheepdog and sheep.
Which of the following sets of Platyhelminthes are you most likely to
contract? - -Fasciola hepatica, Echinococcus granulosus,
Diphyllobothium latum
-Which stage of Trichuris trichiura is infective for humans? - -Eggs
-A human parasite whose segmented body contains both male and
female reproductive organs probably belongs to the group of helminths
known as: - -Cestoda (tapeworms)
-Following treatment for a nematode infection, an adult worm with
cutting plates in its buccal cavity and a sharply bent head was found in
the stool of a woman suffering with severe anemia. The most likely
cause of her anemia was an infection with: - -New World Hookworm
-Consumption of the infective metacercariae encysted on water
vegetation that have not been cooked results in infection with: - -
Fasciolopsis buski or Fasciola hepatica
-Which of the following helminths CANNOT be identified based on the
morphological characteristics of the egg? - -(Any of the organisms
whose diagnostic stage is not an egg, such as) Onchocerca volvulus
(and other Filariae), Trichinella spirlais, Strongyloides stercoralis,
Dracunculus medinensis
