1Small strongyles are the most common and important helminth parasite of horses.
- AVerdadero
- BFalso
2How many species of small strongyles are there?
- A>40
- B30-40
- C10-20
- D20-30
3Following a direct lifecycle, how long does it take for the egg to form infective L3 on pasture and what 2 conditions must be at optimum for this to occur?
- A7 days - moisture and temperature
- B10 days - nutrients and temperature
- C5 days - moisture and temperature
- D3 days - nutrients and temperature
4What is unique to the infective L3 larvae that assists in its survival in the environment?
- ACuticle from L2 - protected and retains viability but cannot feed
- BNutrient storage - ability to feed, remains active and survive until ingested
- CCuticle from L2 - protected, retains viability, can still feed
- DCilli - motility
5Label the lifecycle
- AIngest sheathed L3
- BIngest L4
- CL3 passes through stomach
- DL4 passes through stomach
- ELarvae exsheath in SI
- FLarvae ensheath in LI
- GPenetrate crypts in cecum and colon
- HPenetrate crypts in small intestine
- IEggs passed in feces
- JL4 passed in feces
6Larval stages cause the most significant damage.
- AVerdadero
- BFalso
7What is the prepatent period?
- A6-14 weeks
- B6-8 weeks
- C12-14 weeks
- D4-6 weeks
8Larvae can undergo arrested development and remain encysted in the gut wall for up the 2.5 years.
- AVerdadero
- BFalso
9What is the best diagnostic test for strongyles if a horse is showing clinical signs?
- AFecal egg count
- BELISA
- CDirect fecal smear
- DBaermanns test
10What type of treatment program is being used for effective strongyle control?
- ATargeted treatment
- BScheduled whole herd treatment
11What are the 3 'essentials' of a worm control program?
- AChoice of drug
- BTiming of treatment
- CMonitoring control with fecal egg counts
- DQuantity of drug
- EHousing of horses
12The Egg Reappearance Time is the time period from [blank_start]treatment[blank_end] to when the horse [blank_start]begins shedding Strongyle-type eggs[blank_end] again.
Pyrantel & benzimidazoles - [blank_start]6 weeks[blank_end]
Ivermectin - [blank_start]8 weeks[blank_end]
Moxidectin - [blank_start]10 -12 weeks[blank_end]- Atreatment
- Bfecal egg count
- Cbegins shedding Strongyle-type eggs
- Dtreated for Strongyles
- E6 weeks
- F8 weeks
- G8 weeks
- H10-12 weeks
- I10 -12 weeks
- J6 weeks
13Which anthelmintics have efficacy against arrested Cyathostome larvae?
- AMoxidectin
- BFenbendazole
- CIvermectin
- DPyrantel
14Treatments should be based on [blank_start]fecal egg counts[blank_end].
All horses should be treated every [blank_start]6 months[blank_end] to eliminate [blank_start]large strongyles[blank_end].
[blank_start]High[blank_end] egg shedders (>200-300 epg) should be treated [blank_start]more frequently[blank_end] during times of [blank_start]peak transmission[blank_end]. Do not treat when transmission is [blank_start]low[blank_end].
Maintain a parasite [blank_start]refugia[blank_end] on pasture.- Afecal egg counts
- Bdisease presence and clinical signs
- C6 months
- D12 months
- Elarge strongyles
- Fsmall strongyles
- GHigh
- HLow
- Imore frequently
- Jless frequently
- Kpeak transmission
- Llow feed/poor pasture
- Mlow
- Nhigh
- Orefugia
- Pfree
15Other factors that can be used in conjunction with target treatments include;
- APasture sanitation
- BPasture rotation
- CPasture spelling/alternative grazing
- DIsolate horses
- EIncrease pasture size
16Cyathosomes in horses have developed a resistance to which anthelmintic drug?
- ABenzimidazoles
- BIvermectin
- CMoxidectin
- DPyrantel
