Q

life cycle of Trypanosoma BRUCEI gambiense

A

*Infected tsetse fly bites person
*protozoa moves to lymphatic system and bloodstream
*change forms and travle to organs ans tissues, lympg and spinal fluid
*protoxoa multiple in bloodstream
* fly ingest protozoa when bite infected person
* inside fly - protozoa change form and multilpy
*protozoa travel to fly salvaryglands, multiply and change into trypomastigotrd . that form that inject person

Q

whats is Chagas disease?

A

life treathning causes by parasite tryptosoma cruzi, tranfered whitin feces of biting insects at night, (kissing bugs), trought food, blodtransfusions,
Symtoms 1-2 weeks after fever
Could enlagre liver and speen
Causes: heart damage,

17
Q

most common protozoas in Mastigophora?

A

*Trypnasoma brucei gambriense
*Trypnasomoa cruzi
* Leishmania

18
Q

What is Trupnasomatids?

A

group of kinteoplastid protozoa,
*have one flegelum,
*found in insektsts
host: 1 or 2
caus madjor harm to human sleeping desease

19
Q

how trypanosoma cruzi infect?

A

transmission due to triatoma infestans deposit feces in the skin surface and bite.

20
Q

how is Leishmania transmitted?

A

by sandflies

21
Q

lifecycle of Leishmania?

A

fatal. big liver and spleen.
1. sandflies take blood meal.
2.Promastigotes rapedly change to amastigotes after phagocytosis by macropgaes or monocytes, then multifies, filling cytoplasm
3,infected cell burst, realeases phagocytosed parasites

22
Q

what sickness do Leishmana make?

A

fever, weight lss, splen and liver enlargement. if not treathed=death.

23
Q

whats is sporoza?

A

endoparasite, lack motor structure,
body: tough covering cuticle and singel nucelous.
repr.: binary fission and asexual MOST IMPORTANT PHYLUM

24
Q

What is Coccidiida?

A

cause severe desease in lifestock,
symthom severe diarrhera or dysentery.
* fatal in young foals
*

25
Q

What is the lifecycle of Coccidiida?

A

Sporogony, Schizogony,(multiplefission)Gametogony. first twostages are asexual, with sexual reproduction occurring in the third stage
1. asexual reproduction schizogony occurs in epethelim of human intesine cells
2. sexual reproduction - gametogony, during microgametas ans marcropgages form
3. sporogony formation of oocistas and sporzoites- takes place in external enviroment

26
Q

What is merogony?

A

Sexual reproduction of coocidia in chicken gut

27
Q

what is toxoplasma gondi

A

parasites in cats

28
Q

what is pioroplasmosis?

A

desease in equidae cuased by babesia equi & babesie caballi. transmitted by ticks.

29
Q

kingdom of protozoa

A

Sarcodina
Mastigophora
Sporozoa
Microsporidia
Cnidosporidia
Cilliophora

30
Q

life cyckle of plasmodium?

A
  1. spororzoites in mosquito salavia
    2.multiplication in liver - merozoites released - enter red cells
    3.trophozoite burts blod cells sporozoites infect new bloodcells and small amount of MEROZOITES diferate to male and female
    4.MEROZOITES is taken up by new mosquito in bloodmela.
    5.gamets fused togheter in mosquito forming diplod zygotes which turn into ookinetes.
    6 ookinetes migrate to midgut of insect and form oocysts.
  2. oocysts undergo miotic division ans sporozoites are formes - mifrate to salvaryglands
31
Q

life cyckle of plasmodium?

not finnished!!

A
  1. spororzoites in mosquito salavia
    2.multiplication in liver - merozoites released - enter red cells
    3.trophozoite burs blodd cell

A

single celled, free living. elongated oval with roundend end.
( the coulerd one in microscope)

33
Q

Ciliphoria in general?

A

body covered with pellicle, fine hair like cilia, aquatic free living,. preform specific functions.
BINARY FISSION, sexual repr - conjugation exchange of genetic material between 2 ciliphoria

34
Q

Microsporida in general?

A

eukarotic unicellular,.
obligate, sporeforming intra cellular parasite in vetrebrate and vertebrate.
important parasite in fisheries, vet.med and pest management

35
Q

Haemosporidian in general?

A

bllodparasite of BIRDS, vertebrates.
Vectors: simuliid & culicoides flies- recoverd worldwide

36
Q

Trypanosomatids decscription?

A

kenetoplastid, single flagelum, found primary in insects. cause major desease in humans

37
