Question 1

Feline Herpesviral Diseases causative Agent

Answer 1

FeHV-1 (Alphaherpesvirinae)

Question 2

Infectious laryngotracheitis of Chicken causative agent

Answer 2

GaHV-1 Alphaherpesvirinae, Iltovirus

Question 3

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

Answer 3

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

Question 4

Mareks Disease causative agent

Answer 4

GaHV2: Mareks disease virus serotype 1

Virulent strains: GHV-2 = MDV -1

Question 5

Apathogen strains of Mareks disease

Answer 5

GaHV-3

Question 6

Mareks disease survival in environment and pathogenesis + vaccine

Answer 6

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

Question 7

Mareks disease - acute / chronic form

Answer 7

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!

Question 8

Duck Plague - causative agent

Answer 8

Duck virale enteritis, caused by: AnHV-1 - unassigned Herpesvirus

Question 9

Duck plague: main signs of disease

Answer 9

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

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

Answer 25

enzootic in africa, outbreaks in middle east and in asia transmitted by arthopods fever, necrotic nodules, deep ulceration and scars, ocular lesins, abortion attenuated vaccine, recombinant vaccine scarification for long lasting immunity mortality is medium - there are two statements about mortality and they are both false (neither above 80 nor below 30) abortion replicates in the epithelial cells

Question 41

Myxomatosis different forms, way of infection, occurence, genus, vaccination

Answer 41

``` Leporipox genus world wide arthropod transmission, seasonality! lion head, gelatinous swelling = typical form firm nodules = nodular form conjunctival/respiratory/atypical form recombinant vaccine, attenuated vaccine ``` ``` the european brown hare is NOOOT susceptible, only the european rabbit (NOT in lepus europeus, ONLY in Oryctolagus cuniculus) green fodder and mosquitos conjunctivitis, subcutaenous swellings atypical = respiratory signs mostly seasonal brown hare = asymptomatic carrier nodular form - lower virulence TWO serotypes!!!!!! may result in over 90% mortality typical form = lion head, gelatinous swellings cotton tail rabbits - benign skin lesions NO viremia in cotton tail rabbits ```
