Term
Diphyllobothrium latum
Definition
fish tapeworm
Term
Diphyllobothrium latum
Definition
human and fish eating mammals reservoirs and definitive hosts
Term
Diphyllobothrium latum
Definition
CORACIDIUM LARVAE eggs hatch in water, ingested by crustaceans, develop into PROCERCOID LARVAE. Crustacean ingested by fish, plerocercoid larvae develop in muscles. Humans eat fish. Worms marture in SMALL INTESTINE
Term
Diphyllobothrium latum
Definition
mechanical mucosa irritation=abdominal discomfort
toxins cause peripheral and spinal nerve degeneration
Term
Diphyllobothrium latum
Definition
GI symptoms + PERNICIOUS ANEMIA
Term
Diphyllobothrium latum
Definition
thin shelled, ovoid, OPERCULATED EGGS
Term
Dipylidium caninum
Definition
humans + mammals reservoir/definitive host
fleas and lice intermediate host
Term
Dipylidium caninum
Definition
dog tapeworm
human infection in children ingesting fleas or lice
Term
Dipylidium caninum
Definition
flea larvae or louse nymphs ingest ONCHOSPHERE egg balls, develop into CRYSTICERCOID LARVAE in adult fleas/lice. Dogs/humans ingest adult fleas/lice. Adult worm develops in SMALL INTESTINE.
Term
Dipylidium caninum
Definition
attach via SPINES on rostellum to mucosa. METABOLIC BY-PRODUCTS cause bleeding, inflammation, hemorrhagic enteritis
Term
Dipylidium caninum
Definition
GRAVID PROGLOTTIDS migrate out of anus. or egg packets with ONCHOSPHERES recovered in feces
Term
Hymenoleopsis nana
Definition
does not require an intermediate host
Term
Hymenolepsis diminuta
Definition
requires beetles and fleas ingesting egg to develop
Term
Hymenolepiasis
Definition
insects ingest ONCHOSPHERES, which develop into CYSTICERCOID LARVAE. Human ingest infected insects. Adult tapeworm develops in small intestine.
Term
Hymenolepiasis
Definition
large number of worms and their metabolic wastes needed to cause damage.
Term
Hymenolepiasis
Definition
ovoid, thin shelled eggs containing onchospheres
Term
Taenia solium
Definition
pork tapeworm
Term
Taeniarhynchus saginatus
Definition
beef tapeworm
Term
Taeniasis
Definition
Ingest: onchospheres, develop into CYSTICERCUS CELLULOSAE LARVAE in body tissue
Term
Taeniasis
Definition
cysticerus cellulosae cause nervous system problems.
Adult worms cause GI symptoms
Term
Taeniasis
Definition
eggs with hexacanth embryos and radially striated shells
Term
Hymenolepiasis
Definition
GI symptoms + eosinophila, convulsions, and toxemia
Term
Taeniasis
Definition
adult worms produce intestinal obstruction, inflammation, and irritation at site of scolex attachment.
Term
Taeniasis (T. splium)
Definition
cystecercus cellulosae displaces tissue, leading to caseation and calcification of infected tissues.
Term
Diphyllobothrium latum
Definition
adult worms grow 12 meters with >3000 proglottids
