Swine Viruses Flashcards
Viruses commonly associated with multisystemic/generalized disease:
CSFV (FAD)
*ASFV (FAD)
PRV (extinct from domestic herd, now in feral swine)
PCV 2
PRRSv (highly virulent strains that originated in China)
Viruses commonly associated with Reproduction
PRRS virus
PPV
Porcine cytomegalovirus (PCMV)
Teschoviruses
Sapeloviruses
PRV (extinct from domestic herd)
CSFV (FAD): a pestivirus, similar to BVDv
Viruses commonly associated with Gastro-intestinal system
Rotavirus
PED virus and delta coronaviruses
TGEV
Viruses commonly associated with Respiratory system
PRRS virus
SIV
PRCV
PCMV
PRV (extinct from domestic herd)
Viruses commonly associated with Skin and mucosa
FMDV (FAD)
SVDV (FAD)
*VSV
Seneca Valley virus
Swinepox virus (*mechanical by louse)
Swine vesicular exanthema virus (extinct)
Viruses commonly associated with Neurological disease
Rabies
Teschoviruses
Hemagglutinating encephalomyelitis virus (HEV); a.k.a. vomiting and wasting disease
PRV (extinct from domestic herd)
abortion, anorexia, fever, blue discoloration of snout, ears
PRRS
arteriviridae
severe diarrhea vomiting, dehydration in neonatal pigs, high mortality, glits and sows affected by diarrhea w/o significant consequences
PED virus
coronaviridae
severe diarrhea vomiting, dehydration in neonatal pigs, high mortality, glits and sows affected by diarrhea w/o significant consequences that is NOT PED?
Swine delta coronavirus
significant cause of diarrhea in neonates, looks like a wheel
Rotavirus
enteric disease of newborn and young piglets, not common in well managed herds, seen mostly in biosecurity lax/mixed sourced herds
TGE
coronaviridae
Reproductive failure in naive gilts/sows, early abortion may see death/mummified fetus
Porcine Parvovirus
parvoviridae
causes mulitsystemic wasting disease in swine
assocaited with respiratory, enteric ds, repro failure
Porcine circo virus 2
circoviridae
Reproductive failure, still births, CNS disease in young pigs w/ high mortality rates, diarrhea, pneumonia, pericarditis and myocarditis
Porcine Teschovirus
Pig polio
Picornaviridae
upper respiratory disease, closely related to TGE large deletion mutation
PRCV
coronaviridae
Cause of self limiting vesicualr ds of horses, cattle, swine
looks like FMD, but bullet shaped
Vesicular Stomatitis
rhabdo
vomiting and wasting disease of pigs
Porcine hemorrhagic encephalitis virus PHEv
coronavirus
Aujesky’s dz, generalized systemic disease of swine, repro failure, abortion still births etc abortion storms
Pseudorabies virus
herpesviridae
severe multi-systemic disease of swine, on necropsy see splenic infarcts, pettechial/ecchymotic hemorrhages on serosal surfaces
Classical Swine Fever
Flaviviridae, pestivirus
severe multi-systemic disease of swine, on necropsy see enlarged spleen w/o infarcts, pettechial/ecchymotic hemorrhages on serosal surfaces
African Swine Fever
Asfarviridae
Mild resp in pigs/severe resp in humans
Nipah Virus
paramyxoviridae; henipavirus
