CSF. Flashcards
All wild type pf strains f CSF are highly virulent.
F.
6 distinct serotypes of CSFV are recognized so far.
F.
CSFV is an arbovirus.
F.
CSFV is a zoonotic agent.
F.
CSFV infection has an immunosuppressive effect.
T.
Sus shed CSFV only during the clinical stage of the disease.
F.
Central nervous signs might be seen in CSF.
T.
Based on pathology + Cs, chronic CSF is easy to diagnose.
F.
CSFV spreads slowly in the host + causes mainly chronic disease.
F.
Complicated forms of CSF are rarely seen.
F.
The CSFV may cause reproductive disorders.
T.
Hemorrhages are the most typical lesions of acute CSF.
T.
CSF can unambiguously diagnosed by CS + pathology.
F.
Domestic Sus of most European countries are free from CSFV.
T.
CSF may appear in a milder form in wild boar than in domestic Sus.
T.
Low virulence strains of CSFV may lead to asymptomatic infection.
T.
CSF is spread via infected Sus.
T.
Sows infected by CSF will have immunotolerant piglets.
T.
Piglets of sows vaccinated against CSF are vaccinated at 6 - 12 mnths.
F.
To prevent CSF, we vaccinate Sus older than 6 mnths of age with live vaccine.
F.
To prevent CSF we use inactivated vaccines made from the Chinese strain.
F.
Sheding may start 2- 3 days after 1st CS.
F.
CSF can be prevented by inactivated vaccines.
F.
CSF can hardly be distinguished from ASF.
T.
CSF always causes abortion in Sus.
F.
Hungary does ø have to make any preventative action against CSF.
F.
Incubation of CSF is 8 - 22 days.
T.
CSF was 1st written avout in USA.
T.
1st symptom of CSF is drooping ears.
F.
CSFV has good resistance.
T.
CSFV is mainly transmitted by mosqitoes.
F.
The presence of CSFV in a herd does ø influence reproductive parameters.
F.
CSF is frequently complicated with bacterial infections.
T.
The CS of CSF + ASF are similar.
T.
Central nervous signs are never seen in CSF.
F.
Serological cross reactions may occur between BoVDV + CSFV.
F.
Only inactivated vaccines are available against CSFV.
F.
It is a disease of domestic Sus + wild boars, but several other sp are also susceptible.
F.
Only domestic Sus + wild boars are susceptible.
T.
Fever, anorexia haemorrhages in the skin + weakness of HL are the most important signs.
T.
For prevention state medical steps + vaccination are used in Europe.
F.
The CSFV typically damages endothelial- + lymphatic tissues.
T.
Boutons in the large intestine are the earliest lesions in CSF.
F.
Sus shed CSFV only in the terminal phase of the disease.
F.
Wild boar may play a role in the maintenance + spread of CSF.
T.
In Europe vaccination of domestic Sus against CSF is common.
F.
CSF is a notifiable disease in Europe.
T.
In Europe vaccination of domestic Sus populations against CSF is compulsory.
