16
Q

What is the most likely cause of these lesions

seen in pigs; it also causes arthritis in piglets,

and abortion secondary to fever and septicemia

A

Erysipelothrix rhusiopathiae

17
Q

What is the causative agent of PRRS?

A

Arterivirus

18
Q

This disease has caused the most problems in swine industry.

See up to 10% mortality in sows and 100% in piglets.

The agent can be transmitted in the semen, and is the reason

we shower in and shower out of pig production.

A

PRRS (Arterivirus)

19
Q

PRRS causes sows with premature farrowing,

stillbirths/mummies, weak neonates, and abortion.

When do abortions occur?

A

Late gestation

20
Q

How is PRRS diagnosed?

A

herd serology (PCR)!

21
Q

This causative agent of infertility in sows

is characterized by

SMEDI = Stillbirths, mummies, embryonic death and infertility

A

Porcine parvovirus

22
Q

This causative agent of infertility in pigs causes:

Embryonic and fetal death with no maternal signs.

Females may nest and get mammary development,

but may fail to farrow.

Dead fetuses with lesions at birth.

Sows infected do not normally show signs until farrowing = small litter size and increase number of mummies

A

Porcine Parvovirus

23
Q

How is Porcine parvovirus diagnosed?

A

Clinical signs and serology (FAT test)

of tissue from aborted fetus

24
Q

How is porcine parvovirus prevented?

A

Proper acclimatization of replacement gilts

Lepto, parvo vaccination EVERY 6 MONTHS

25
Q

What is the causative agent of Pseudorabies?

A

Herpesvirus

26
Q

This causative agent of infertility in pigs can causes:

CNS signs in piglets less than 1 week old

Respiratory signs in weaned piglets and older

Fever, anorexia, and weight loss at all ages

Resorption, abortion and increased mummies and stillbirths

A

Pseudorabies (Herpesvirus)

27
Q

How is Pseudorabies controlled?

A

Eradication- whole herd depopulation!!

28
Q

What is the causative agent of Hog Cholera

(Classical Swine Fever)?

A

Pestivirus

29
Q

Pigs are the only natural host of this disease that causes infertility in pigs.

CLINICAL SIGNS include anorexia, cyanosis, fever, diarrhea, vomiting, abortions

This was eradicated in the 1970s!

A

Hog Cholera (Classical Swine Fever Pestivirus)

30
Q

The estrogenic metabolite produced by

Fusarium roseum fungus

A

Zearalenone

31
Q

What is the agent that causes the following?

Causes implantation failure

Females exhibit signs of estrus, mammary development, and vaginal discharge

See vaginal and/or rectal prolapses

Prepubertal males have reduced testicular development and feminization

A

Zearalenone

32
Q

Carbon monoxide poisoning

causes late term abortions in pigs.

____ ppm is toxic

A

220 ppm

33
Q

You’re called out to a piggery with

a history of heater failure in the gestation barn .

Pigs have CHERRY RED TISSUES,

and there have been some late-term abortions

What is your primary ddx?

A

Carbon monoxide poisoning

34
Q

Toxoplasma causes individual abortion and stillbirths

_____, not rodents, act as reservoirs

A

cats

35
Q

Eperythrozoonosis

Causes silent estrus or anestrus, abortion, weak/anemic piglets and can cross the placenta, also lyses RBC.

How is it transmitted?

A

Lice or mites

36
Q

Eperythrozoonosis

Causes silent estrus or anestrus, abortion, weak/anemic piglets and can cross the placenta, also lyses RBC.

How is it treated?

A

Treat whole herd with ARSENICS
