Diseases caused by protista
Malaria / Dysentery
Malaria
• Malaria is a disease
caused by a parasite called
plasmodium , a sporotozoan
(animal like protist).
It was a major case of deaths
during all human existence
but took the state a full scale
epidemic during the XX
century.
Infection
Only anopheles mosquitoes
are the know vectors for transmissing
malaria .But for the mosquito must
have ben infected form a previous blood
meal taken on a infected human.
Life cycle
When a plasmodium enters a human
system it travels to the
liver cells through the blood vessels .
There they transform into
merozoites that after develop into
gametocytes which are the
precursors of gametes .
When another mosquito bites this
human new spores migrate .
Contagious or not ?
Until now the only
way known for the
transmission of malaria
is by one kind mosquito.
So we can’t call it contagious
or infectious .
Where does malaria occur
Malaria commonly occurs in Africa ,Asia ,South America
,Central America ,Southern Mexico and Caribbean .But the
most occurrences happen in Sub-Saharan Africa .These
countries have a big amount of plasmodium falciparum
which is the most dangerous of the four species.
Symptoms
Symptoms of malaria
may include fever ,chills
,vomiting ,couch
,stomach pain , muscle
aches ,weakness .
If infected with the
most severe form of
malaria and if left
untreated it can cause
serious illnesses like
seizures ,mental
confusion ,kidney
failure ,coma and
death .
Treatment
Malaria is treated with a class of drugs
called anti malarial.
antimalarial drugs are designed to
attack the parasites that cause malaria
,preventing them from spreading while
also killing them off so they can’t continue
causing infection .
Dysentery
Dysentery is caused by
Entamoeba histolytica
which is a parasitic
protozoan .
Its main targets are humans
and other primates.
Infection
Dysentery can only
and only enter in the
human system through
oral input . It can be
rendered possible when a
person drinks turbid water.
Also people who consume
infected feces but that’s a very
rare case and the persons in
words had mental disorders .
Life cycle
Symptoms
Symptoms of amoebic dysentery include:
• abdominal pain
• fever and chills
• nausea and vomiting
• watery diarrhea, which can
contain blood, mucus or pus
• painful passing of stools
• fatigue
• intermittent constipation.
What does it cause ?
Entamoeba histolytica that,
among other things,
can cause severe diarrhea with
blood. But it may cause milder
chronic symptoms of:
frequent loose stools ,
abdominal pain
Treatment
Treatments for dysentery
Rehydration therapy
Antibiotics and amoebicidal drugs
Antirheumatic drug Ridaura
