Trematodes Flashcards
Known as the FLUKES
TREMATODES
Complete lifecycle with at least ? how many host
2 hosts
Primary host where the flukes sexually reproduce?
vertebrae
What is the shape of trematodes?
Leaf shaped
True or False: does trematodes have only male reproductive organ?
False because trematodes is hermaphrodite meaning it has female and male reproductive organ.
They have outer cover called
TEGUMENT
The tegument may be smooth or spiny except for the
blood flukes
Bilaterally symmetrical helminths without a body cavity is called?
Acoelomate
Trematodes is barely in size except:
heterophyase and metagonimus
Primarily for Attachment and secretion
integument
Cup shaped (usually found in the anterior part of the trematode)
Suckers
A saucer shaped organ of
attachment in flatworms
Acetabulum
A specialized sucker for
parasitic adaptation in
trematodes, by which the
worms where able to attach
on the host.
Acetabulum
How many testes does trematodes have?
2 testes
How many ovary does trematodes have?
1 ovary
Has fluid -filled between organs
ATTACHMENT
Has 2 testes excpet?
schistosomes
2 testes can be?
can either be globular, lobate,
tubular, dendritic
cuplike polar operculum except for schistosomes
Ova
What is movement of TM?
contraction and elongation
What is the 2 nutrition materials of TM
INSOLUBLE MATERIALS
SOLUBLE MATERIALS
Regurgitated to the oral sucker
INSOLUBLE MATERIALS
Distributed by lymph
SOLUBLE MATERIALS
In excretion, it is eliminated through?
flame cells
In respiration, it is _________ except in larval forms which is ____________
Respiration: anaerobic except on its larval forms (aerobic)
Reproduction of TM is?
hermaphroditic
Vertebrae and Sexual generation
DEFINITIVE HOSTS
In DEFINITIVE HOSTS, the eggs will escape through the?
intestines, genitourinary and pulmonary
mollusks is an IH or DH
IH
These are important in the life cycle of which there is a sexual generation?
mollusks
What is the 5 pathology of TM?
LIOEI
- lesions
- irritation
- obstructions
- embolism
- immunologic like in the case of schistosomes
TREATMENT of TM?
Praziquantel
- Bithiono
The trematodes which is commonly
known as flukes usually vary in egg,
larva, morphology and reproduction
processes
MONOECIOUS/ DIOECIOUS FLUKES
Trematodes can be divided into 2
groups
a. MONOECIOUS/ HERMAPHRODITIC
b. DIOECIOUS/ BLOOD FLUKES
has male and female reproductive system in one parasite and can do self-fertilization
MONOECIOUS/ HERMAPHRODITIC
parasite that reproduce via separate
sexes.
DIOECIOUS/ BLOOD FLUKES
secrete proteases, lipases, ACP, ALP & esterases
Gastrodermal cells
if they can self-fertilize, they usually
infect organs, they are food-borne.
MONOECIOUS/ HERMAPHRODITIC
DIOECIOUS/ BLOOD FLUKES can infect by?
direct penetration
True or false: MONOECIOUS/ DIOECIOUS FLUKES have a
mouth but they don’t have anus
True
Common to all trematodes is their complex
life cycle which almost always include your __________
especially ___________ as intermediate
host.
snails, mollusks
Primarily for digestion
Ceca
Gastrodermal cells is under?
Ceca
Flask-shaped with a tuff of
fused flagella
Excretory System
This are specialized excretory cells
which functions like a kidney
in which they remove waste
materials?
Flame cells
Bundle of f lame cells or group of flame cells is called
Protonephridia
