PQS - Hungarian 2023 Flashcards
Hepatitis is notifiable
T
Hepatitis is transmitted by blood transfusions or sexually transmitted
F?
most is contaminated by fecal oral route, but can be transmitted trough blood transfusion hepatitis E and sexual transmission is less common but can happen ex: hepatit C
If they mean hepatitis E if other hepatitis then true
Hepatitis causes no symptoms in humans
F
Causes only symptoms in humans
Western equine encephalitis is only in Nort-America
F
Canada - through USA west coast and mexico down to South-America
Venezuelan equine encephalitis is only in South-America
F
USA southern states, Central America and South-America
Border disease causes bloody diarrhoea in sheep
F
ASF causes cytoplasmic inclusion bodies
T
ASF is present in wild boars in Europe
T
Africa: Warthog
ASF is transmitted by ticks in Europe
F
In Africa, but also in Spain and Portgual
In the epidemiology of bovine viral diarrhoea immunotolerance plays a great role
T
In utero infection with non cytopathic BVDV can cause immunotolerance
The antigeniectiy of reovirus is uniform
F
We do not use serological methods to detect ASF
F
you can use ELISA- positivity confirmed with western blot
Duck viral hepatitis causes symptoms in 1 month old or younger ducklings
T
Causes clinical signs in 1-4 week olds ducklings
African horse sickness virus 1 week long viraemia in zebras
F
Horse: 4-8(18) days
Zebra: 28 days
Bluetongue virus is transmitted by soft ticks
F
By midges and gnats
Rotavirus damage the colon
F
We see damage in the small intestines
Tick-Born encephalitis in animals usually do not cause clinical symptoms in humans
T
Clinical signs in animals usually, in humans frequently subclinical infections
Ibaraki disease of horse nervous system
F
It is a disease of cattle in Japan, similar to bluetongue
Epizootic haemorrhagic fever disease causes endothelial damage
T
BVD causes a disease similar to border disease in sheep
T
Mucosal disease is the most common form of BVD
F
Most severe outcome, but is very rare
Infectious bursitis causes acute disease in 3-6 week old chickens
T
The vesicular exanthema (VES) in pigs is maintained by seals
T
Swine vesicular disease (SVD) causes disease in humans
F
Only in pigs
There is currently no vaccine for swine vesicular disease (SVD)
T
Swine vesicular disease (SVD) does not spread form pig to pig
F
Spread by direct contact of swine
West Nile fever does not cause symptoms in wild birds
F
Can be both asymptomatic and have clinical signs. Some wild birds are more sensitive than others
West nile fever is maintained by rodents
F
Birds are the maintaining/reservoir host
RHDV - 2 only causes disease in burrowing/house rabbits
F
RHDV-2 = rabbits and hare
RHDV-1 = rabbits
The primary symptom of infectious encephalitis in chickens is shaking of the head
Infectious bursal disease?? If so, then false
In the case of BVD, infection with a non-CP strain causes skull lesions
F
Cytopathogenic strain = foetal damages, abortion, developmental disorders
Non-cytopathogenic strain = infertility, immunotolerance, immune response
Chicken liver and spleen disease is spread by drinking water contaminated with faeces
T
Rotaviruses are transmitted by faecal – oral route:
T
Infectious bursitis is highly contagious
PQS: Bursitis virus is highly contagious
T
FMD does not cause viraemia
F
They DO cause viraemia
Swine vesicular disease (VES) is more contagious than FMD
PQS: VES is more contagious than FMD
F
FMD is highly resistant
T
Even though they are enveloped, they have a high resistance
In the case of feline calicivirus, visible blisters in the mouth can be of diagnostic value
T
We only vaccinate against infectious bursitis with inactivated vaccines
F
Live, attenuated vaccines + immune-complex vaccine
Inactivated used for booster mainly
Norovirus cause gastrointestinal symptoms in humans
T
Equine encephalosis causes abortion (miscarriage)
PQS: Equine encephalosis can result in abortion
T
African horse sickness is spread through, semen and urine
T
Spread through semen, urine and discharge
American equine encephalitis is spread by mosquitos
T
think they mean the EEEV, WEEV and VEEV cause they are only present in america and it is transmitted by mosquito
American?? They say its true
ASF is reproducible in vivo
F
