3. PRRS
4. E.coli
5. Clostridium perfringes
6. Coccidiosis

Question 3

features of rotavirus and how to limit

Answer 3

very common and prevalent
usually non-fatal.
ensure good hygine with sufficient heat in environment.

Question 4

what virus is PED/TGE and when are pigs mostly affected

coronaviruses
<4 wks old
usually self limiting
new variant causing bright yellow feaces and is more fatal

Question 5

how are piglets infected with PRRS and what other clinical other than scour is caused

Answer 5

piglets infected in utero during a disease breakout in the herd.
scour, conjunctivitis, brusing and anemia seen

Question 6

when do piglets get E.coli and what does the scour look like

Answer 6

occurs during first week of life
watery/CREAMY scour seen

Question 7

treatment and prevention of e.coli scour

Answer 7

hydration and antibiotics
vaccination of breeding herd

Question 8

what makes clostridium perfringes scour stand out

Answer 8

death!
type-C causes sudden death in 24hrs due to haemorrhagic enteritis (outdoor systems mostly
type-A low mortality, mild scour

vaccination for long term control

Question 9

when are piglets usually affected by coccidiosis and what is the type of scour seen

Answer 9

10-21 days old piglets
PASTY YELLOW feaces seen

Question 10

treatment of coccidiosis

Answer 10

no treatment
control by giving piglets oral toltrazuril at 4 days old
coccidiosis does self resolve at weaning however weaning weight much lower as a result

Answer 14

porcine haemorrhagic enteropathy
porcine intestinal adenopathy

Question 15

clinical signs of lawsonia diseae

Answer 15

sub clinical form: thickened distal ileum causing malabsorbtion and weight loss
acute form: haemorrhagic diarrhoea with rotten blood smell and blood clots seen in intestinal lumen

Question 16

what ages do pigs get salmonella

Answer 16

all ages but most common in wenaers and growers

Question 17

clinical signs of salmonella

Answer 17

pig is fucked

E.coli
salmonella

Question 21

characteristic E.coli infection

Answer 21

sudden onset waterzy diarrhoea ONE WEEK post weaning.
apramycing to treat

Question 22

characteristic salmonella infection in weaners

Answer 22

low grade scour usually
necrotic enteritis causes high grade high mortality diarrhoea

Question 23

what is the notifiable disease causing diarrhoea

Answer 23

porcine epidemic diarrhoea
coronavirus causing. profuse watery scour and vomiting
PED type 1 in growers
PED type 2 in other pigs

Question 24

PRRS has many different clinical presentations depending which stage of their lives pigs are affected.
describe PRRS clinical disease in neonate, grower, finisher, sows and boars

Answer 24

neonate=dyspnoea, CNS signs, scour, anemia, high mortality
grower=failiure to thrive
finisher=fever and less food consumption
sow=abortion, stillborn or weak pigs
boar=fever, semen changes
