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.
