,INFECTIES DOOR GECONTAMINEERD DRINKWATER
1. Spirometra spp (sparganosis) (H3 pag 8)
2. Dracunculus medinensis (H4 pag 44) ter volledigheid
3. Giardia (H6 pag 6)
4. Entamoeba histolytica (H6 pag 18)
5. Cryptosporidium parvum (H6 pag 40)
6. Balantidium coli (H6 pag 53)

1) SPIROMETRA SPP (SPARGANOSIS)
PHYLUM: CESTODA – ORDE: PSEUDOFILIDAE
GENUS: SPIROMETRA SPP
Kenmerken - Eindgastheer is hond of kat
- Belangrijk is dat mens hier als tussengastheer kan dienen!

Cyclus Sparganosis: mens kan besmet worden door gecontamineerd drinkwater, rauwe
zoetwatervis en traditionele wondbehandeling. De mens kan besmet worden met de
Term examen procercoïd via de cyclops, die zich dan ontwikkelt tot plerocercoïd of direct met de
plerocercoïd besmet raken. Doordat de mens geen eindgastheer is, is het een
LIJSTJE paratenische tussengastheer. De Spirometra gaat hierdoor migreren door het lichaam
drinkwater en en subcutaan zitten (kan ook in het oog → dan conjunctivitis).
rauwe vis

Behandeling Mens: Hier werkt Praziquantel niet, want het zit niet in de dunne darm hier! Dus je
moet het chirurgisch gaan verwijderen.

Kat en hond: Praziquantel is hier wel mogelijk.

Preventief: voedsel goed koken en drinkwater filteren.

,2) DRACUNCULUS MEDINENSIS - TER VOLLEDIGHEID
PHYLUM: NEMATODA – ORDE: SPIRURIDA
GENUS: DRACUNCULUS SPP. (GUINEA WORM)
Dit kan alleen op het examen gevraagd worden als term, denk aan guinea worm. Je krijgt een blaasje,
ulcur met de vrouwelijke worm erin. Deze worm kan 1-4 m worden! In contact met water knapt de
blister open en ook gaat de uterus de eitjes vrijzetten → L1 larves in het water.
Algemene - Tussengastheer is een cyclops (kennen we al van Diphyllobothrium latum en
kenmerken Ligula intestinalis)
- Microscopisch klein, worden geassocieerd met waterputten (Jemen, Sudan).
LIJSTJE Infectie door ongefilterd water te drinken.
drinkwater - Ziekte is door WHO onder controle door water te filteren.
ter
volledigheid

Symptomen Ze komen finaal op de extremiteiten en vormen daar een brandend pijnlijke
subcutane blaar. Wanneer de geïnfecteerde persoon in het water is, barst de blaar
open komen de larven terecht in het water.
− De worm is 1-4 meter lang → alleen het laatste stukje van de vrouwelijke
worm steekt in de blaar.
− Je krijgt de worm eruit met een stokje, die je dagelijks een stukje gaat draaien
→ niet te veel, want dan trekt de worm zich terug en krijg je een ontsteking .

Behandeling Ivermectine of BMZ

3) GIARDIA
PHYLUM: MASTIGOPHORA – ORDE: DIPLOMONADIDA – FAMILIE: HEXAMITHIDAE
GENUS: GIARDIA SPP.
Algemene - Wereldwijde verspreiding maar vooral warmere streken.
kenmerken - GH-specifiek, niet zo invasief blijft heel oppervlakkig.
- Bevat 2 kernen → practicum! Ook bevat het een flagel en een adhesive
disk/hechtschijven. Dit zijn zuigorganellen en zorgt ervoor dat de protozoa kan
vasthechten op de enteroct.
- Cystevormers dus besmetting vanuit omgeving. De cyste bevat 4 kernen.
- Binaire deling.
Species Te kennen species: Giardia lamblia (synoniemen: G. intestinalis, G. duodenalis). Is
nog onderverdeeld in 6 antigene groepen (assemblages), gebaseerd op rRNA

, sequentie. De mens komt in 2 van deze assemblages voor (waarbij type B een
zoönose is, typisch in de kalverhouderij. Type A komt voor bij de mens). Het is een
zeer veel voorkomende parasiet bij mensen. Veel zoogdieren kunnen als reservoir
dienen, voornamelijk aquatische species, zoals bevers.

Giardia lamblia: Er zijn verschillende Ag types:
o A = mens
o B = mens + rund
o C en D = hond
o E = rund
o F = kat

Morfologie Zijn traanvormige trophozoïeten met ventraal een verklevende schijf. Ze hebben 8
flagellen en 2 nuclei. Wanneer ze matuur zijn: ellipsvormige cysten met 4 nuclei. De
cysten bevatten 4 kernen, zijn resistent en verantwoordelijk voor de transmissie van
giardiasis. Een infectieuze cyste bevat 2 trophozoiten. Worden vrijgesteld via SVS, zijn
direct infectieus bij uitscheiding. Trophozoiten kunnen niet overleven als je opneemt
(in maagzuur) dus je zou direct een cyste moeten binnenkrijgen. Gaan een monolaag
vormen op de enterocyten waardoor er geen goede opname kan zijn en er een
waterige/vettige diarree is.

Cyclus − Zowel cysten als trophozoïeten kunnen worden teruggevonden in de faeces
(diagnostisch stadium → flottatie). De cysten kunnen voor meerdere maanden
overleven in koud water (1)
LIJSTJE − Infectie vindt plaats wanneer je gecontamineerd water of voedsel binnenkrijgt
drinkwater of via de faecale-orale route (handen) (2). Incubatieperiode is 2 weken.
− In de dunne darm komen de cysten uit → uit elke cyste komen twee
trophozoïeten (3).
− Trophozoïeten gaan vermeerderen via longitudinale binaire splitsing (aseksueel)
en blijven in het lumen (vrij of vast aan de mucosa d.m.v. de verklevende schijf
op het abdomen). Ze voeden zich aan de muceuze secreties van darmcellen,
grotere aantallen kunnen de absorptie van voedsel blokkeren, waardoor het
steatorrhee veroorzaakt. (4).
