Q

Speciality of the epizootiology and pathogenesis of infectious laryngotracheitis of chicken + vaccine?

A

No viraemia, no germinative infection, birds die because they CANT SNEEZE OR COUGH so they suffocate to death
attenuated vaccine into the drinking water

Q

Mareks disease survival in environment and pathogenesis + vaccine

A

in feather follicular epithel cells and dust for about 1 year survival

vaccination is available but doesnt prevent from infection

lymphoproliferative form = acute in 6 week old chicken (tumors all over the body)
and chronic neurological form and visceral form

Q

Mareks disease - acute / chronic form

A

acute: visceral form, very virulent, higher mortality - tumor infiltration of the viscera, lymphoproliferative
chronic: neurological form - weakness, ataxia, paralysis, eye lesion can lead to blindness (neurological signs)

true:
transient paralysis, lymphoproliferative form in 6 week old chicken or turkey= acute form
turkey herpesvirus causes cross immunity and can be used for vaccination
bc of vaccine clinical signs are rare
in ovo vaccine exists
NO germinative infection but infection through egg shell
survives for long in environment
similar to reticuloendotheliosis, avian leukosis
recovery is an exception!
mainly through aerogenic, NOT mainly through faeces
the low virulence strains cause chronic, mainly neurological signs
highly virulent strains may break through vaccine and protection!

Q

Duck plague: main signs of disease

A

duck plague/viral enteritis
sudden and persistent increase in flock mortality
photophobia, eyelid edema, conjunctivitis
convalescent birds are lifelong carriers
wild ducks are important in spread of disease
acute haemorrhagic disease of duck and other waterfowl
death within 4-6 days
muscovy ducks, geese

mallards may transmt the duck enteritis to domestic ducks kept on lakes
liver dystrophy as frequent lesion
persistent infection in wild ducks
may be shed lifelong
often fatal - there is no treatment
damages the blood vessel endothelium
vaccines containing a live attenuated strain can be used for prevention
can settle in wild ducks
also effects geese
can affect all age groups
depression, resp signs and bloody diarrhea

milking machine transmission, recovery without pockmarks, no long immunity, no vaccine available

22
Q

Bovine papular stomatitis age, diagnostics specials

A

mostly in calves under 1 year, may persist for 3-4 months, mild disease with lesions on mouth, lips, gums, zoonotic transmission so dont mix up with FMD

23
Q

Contagious pustular dermatitis

A
Echtyma contagiosum, scaby mouth, Orf
parapox
worldwide presence
very resistant in environment
sheep and goat, humans too
lips, muzzle, tonguem gums - papules, wont eat
zoonotic
vaccine for prevention - attenuated vaccine
common in young lambs
zoonotic disease
can infect goat
lameness
common in young lambs
virulent vaccines are used
can survive in environment for ages
zoonotic agent
strong crustation
no maternal immunity
muco-cutaneous junction - lesions
24
Q

Lumpy skin disease aetiology

A

lumpy skin disease virus, capripoxvirus genux

ruminants are susceptible,

25
Q

lumpy skin disease occurence and vector, clinical signs, vaccine

A

enzootic in africa, outbreaks in middle east and in asia
transmitted by arthopods
