What is the intermediate host for Fasciola hepatica?
snail: lymnaea truncatula
29
Liver Trematodes have different stages in their lifecycle. At one of the stages of it’s life, the parasite is very vulnerable and can die within 24 hours if not in the correct environment. Identify the name of this stage of the parasite’s lifecycle using the picture below.
cercaria
30
In which of the following species are eggs passed in the faeces during a fascioloidosis infection?
deer
31
outline the sequence of development for a typical fasciola
Egg --> metacercaria --> sporocyst and redia --> cercaria --> miracidium --> adult
32
A pregnant woman with a house cat shouldn’t clean the litter box to avoid catching which disease?
toxoplasmosis
33
What lifecycle does Toxocara canis follow?
a combo of direct and indirect
34
Q11. What parasite do you expect this to be based on the information
Nematodirus battus
35
You have found something on the faecal sample, identify what it is?
nematode egg
36
how should a farmer prevent N battus infection
- rotational grazing
- dont keep older ewes with lambs
- deworm pregnant ewes beofre and after lambing
37
Which equine parasite would most likely be associated with this ‘summer sore’?
habronema
38
What parasite is characterised by the white/yellow sticky eggs on the legs of horses?
gasterophillus spp
39
giardia
40
hookworm
- thin shelled, transparent
41
dipylidium caninum
42
Clinical haemonchosis in lambs most commonly includes:
anaemia and hypoproteinaemia
43
why does bottlejaw occur
loss of protein and oedema
44
In utero infection can take place in which of the following parasites?
toxocara canis
45
type 1 ostertagiosis occurs in young or old animals
young animals
46
Hypobiosis is a mechanism developed by some nematode species to :
ensure survival during harsh weather
47
which of the wollowing parasites is a serious infection in game birds
trichostrongylus tenius
48
Damage caused by oxyuris equi infection is caused by?
egg laying behaviour of the females
49
What factor in the epidemiology of haemonchosis contributes MOST to contamination of the pasture early in the year, providing a source of parasites for young lambs?
spring rise where eggs overwinter on pasture and ewes shed eggs because periparturient relaxation of immunity
50
anoplocephala perfoliata
51
- A trichostrongyle nematode of ruminant
- Development of larvae from L1 to L3 occurs within the egg
- Its egg is very resistant in environment
- Causes severe diarrhoea and sudden death in lambs
- Can be identified from other gastrointestinal nematodes by it characteristically large sized eggs
what parasite am I
nematodirus battus
