2what types of growths will each spp pesent with

- BFalso
5which are true regarding papilloma virus
- Amalignant transformation of dermal cell
- Bthere is a vaccine
- Cone can crush the wart to release virus into blood vessels to initiate immune response
- Dwarts grow only on the skin
- Epapillomavirus is not spp specific
- Fpapilloma virus has been associated with squamous cell carcinoma in sheep

6Bovine viral diarrhoea and mucosal disease :
- Aare both caused by bvdv
- Bcan infect horses, cattle, sheep, goats, pigs
- Cthere are three gentoypes and two biotypes (phenotypes)
- Dnon cytopathogenic strain becomes mutated to form the cytopathogenic strain
- Ethe virus is shed only in infected animals
- Fif infected between 100d and 150d, animal born healthy
- Gif infected between day 50-125: the foetus developed immunotolerance and is born persistently infected
- Hthere is only one vaccine: modified live which is safe for pregnant animals
- Iif infected between 140d and birth, animal born healthy and normal
- Jif infected between 0-200 day, early embryo death occurs
7there is an inactivated and modified live vaccine available
- AVerdadero
- BFalso
8if animal infected by bvdv between 0-175 day, [blank_start]eed[blank_end] will occur.
if infected between 50-125 day, the foetus will become [blank_start]immunotolerant[blank_end].
superinfection of a persistently infected calf will result in [blank_start]mucosal disease[blank_end].
if infected between 100-150 days, the foetus with be [blank_start]teratogenic[blank_end].
if infected between day 140 to birth, the feotus will be born [blank_start]normal[blank_end].- Aeed

- AVerdadero
- BFalso
11one can diagnosis bvdv by: isolation ( [blank_start]serum and nasal swabs[blank_end]), by ELISA (detecting for [blank_start]Ag and Ab[blank_end]), PCR. one can test persistently infected animal by doing an [blank_start]ear punch biospy[blank_end]
- Aserum and nasal swabs
- BAg and Ab
- Cear punch biospy
12mucosal disease can present with: [blank_start]erosions[blank_end] on mucosa, [blank_start]emaction[blank_end], water and [blank_start]profuse[blank_end] diarrhoea
- Aerosions
- Bemaction
- Cprofuse
13Apart from transplacental effects, BVDV can present as [blank_start]acute BVDV[blank_end] or cause [blank_start]immunosuppression[blank_end]
- Aacute BVDV
- Bimmunosuppression
14mild acute bvdv will present with: [blank_start]diarrhoea[blank_end] and [blank_start]enlarged[blank_end] lymph nodea
moderate bvdv will present with depression, [blank_start]watery[blank_end] diarrhoea, [blank_start]oral[blank_end] erosions
severe acute bvdv will present with : [blank_start]bloody[blank_end] diarrhoea, [blank_start]epistaxis[blank_end] and petechiae- Adiarrhoea
- Benlarged
- Cwatery
- Doral
- Ebloody
- Fepistaxis
15another name for border disease is [blank_start]fuzzy lamb disease[blank_end]
- Afuzzy lamb disease
16regarding border disease, which are true
- Ainfection of sheep in the 2nd trimester
- Blambs that survive become PI
- Cthese lambs have abnormal haircoats and deficiency of lipids in the fibres
- Dlambs can be born with congential defects
- Ethe abnormal haircoats are due to cns defetcs
- Fthere is a vaccine to prevent
17infection of sheep foetuses with border disease occur during the [blank_start]first[blank_end] trimester.
the following can result: [blank_start]EED[blank_end], [blank_start]abortions[blank_end] or lambs born with [blank_start]congenital defects[blank_end].- Afirst
- BEED
- Cabortions
- Dcongenital defects
18bvdv is a zoonosis
- Afalse
- Btrue
19wesselsbron is a zoonosis
- AVerdadero
- BFalso
20wesselsbron can be transmitted
- Aby culicoides
- Bby anopheles
- Cby aedes
- Dtransplacentally
21wesselsbron is mainly a disease of [blank_start]newborn small stock[blank_end].
in adult small stock and cattle, a [blank_start]mild febrile reaction[blank_end] can be seen.
this is a [blank_start]hepatotrophic[blank_end] virus .- Anewborn small stock
- Bmild febrile reaction
- Chepatotrophic
22diagnosing wesselbsron
- Aculture
- Bisolation
- Cpcr
- Dhistopathology
23calves will present with widespread oedema and heamorrhages
- AVerdadero
- BFalso
24west nile fever is a zoonosis
- AVerdadero
- BFalso
25west nile fever is a respiratory disease
- AVerdadero
- BFalso
26[blank_start]birds[blank_end] are tje amplifying and transport hosts.
the vector is [blank_start]culex[blank_end] mosquito.
the species effected are [blank_start]horses[blank_end]- Abirds
- Bculex
- Chorses
27what is false for west nile fever
- Aone can control using vaccines
- Bone can control using midges control
- Cthere are 3 lineages
- Dencepahlitis, vomition, staggering gait and paralysis of hind limbs are the clinical signs
28bovine emphemeral fever is a zoonosis
- AVerdadero
- BFalso
29bovine ephermal fever is transmitted
- Adirectly
- Bby culicine and anopheline
- Cby culicoides
30Bovine ephemeral fever is aslo known as [blank_start]three day stiff sickness.[blank_end]
Species effected influde cattle and [blank_start]water buffalo[blank_end]
[blank_start]lactic acid[blank_end] accumulation after death inactivates the virus
no oral treatment is given beacause of [blank_start]rumen atony[blank_end]- Athree day stiff sickness.
- Bwater buffalo
- Clactic acid
- Drumen atony
31bovine ephemeral fever virus causes a major [blank_start]inflammatory response[blank_end] which damages [blank_start]small endothelial cells[blank_end] and also results in hypocalceamia due to [blank_start]rumen atony[blank_end]. The inflammation can lead to a temporary [blank_start]infertility[blank_end], [blank_start]joint[blank_end] swelling, decrease in [blank_start]milk[blank_end], [blank_start]tachy[blank_end]cardia, [blank_start]emphysema[blank_end] in lungs. Hypocalceamia will present as a temporary [blank_start]paralysis and tremors.[blank_end]
- Ainflammatory response
- Bsmall endothelial cells

- Fmilk
- Gtachy
- Hemphysema
- Iparalysis and tremors.
32one can diagnose bovive ephemeral fever by
