Answer 7

Highly contagious VIRAL disease affecting pigs on all ages
Newborns less than 10
Caused by corona virus

Spread by aerosol, direct fecal contact or fomite
Incubation

Question 8

Transmissible gastroenteritis:host risk factors

Answer 8

Parity
Herd immunity levels
Environmental/management factors (all in all out)

Question 9

Transmissible gastroenteritis: pathogen risk factors

Answer 9

Persists in environment for a few weeks
Survives freezing
Sensitive to light and disinfectants

Question 10

Transmissible gastroenteritis: immune response

Answer 10

Strong antibody response ( IgA in intestinal tract protection)
SIgA (excreted in sows milk and passive immunity for piglets)

Best passive immunity from natural GI infection of the sow

Question 11

Transmissible gastroenteritis: pathogenesis

Answer 11

Nasal secretions and milk-replicates respiratory intestinal tracts

Destroys epithelial cells jejunum and Illium

Question 12

Transmissible gastroenteritis: clinical signs

Answer 12

Vomiting, intense thirst, dehydration
Diarrhea
Pigs less than a year old die
Abortion

Question 13

Transmissible gastroenteritis: diagnosis

Answer 13

Clinical signs
Necropsy
Antibodies of intestinal contents

Question 14

Transmissible gastroenteritis: treatment and control

Answer 14

No specific treatment
Increase farrowing room temp
Vax
Feed ground up dead to sows
Sanitation 

RECOVERED PIGS ARE IMMUNE FOR ONE YEAR

Question 19

Transmissible gastroenteritis (TGE)

Answer 19

HIGHLY contagious a VIRAL disease

Caused by coronavirus
Spread through aerosol, direct fecal oral contact, or fomites
Epidemic: explosive in naive herds–lasts 3-5 weeks
Endemic: partial immunity, contagious introduction of susceptible pigs

Question 20

Transmissible gastroenteritis (TGE): HOST risk factors

Answer 20

Parity
Herd immunity levels
Environmental/management factors (continuous flow)

Question 21

Transmissible gastroenteritis (TGE):PATHOGEN risk factors

Answer 21

Persists in environments for a few weeks
Survives freezing
Sensitive to light aNd disinfectants

Question 22

Immune response

Answer 22

Pigs develop strong antibody response (IgA)
sIgA: excreted in Sows milk_passive immunity
BEST PASSIVE IMMUNITY FROM NATURAL GI INFECTION OF SOW

Question 23

Transmissible gastroenteritis (TGE): clinical signs

Answer 23

Vomiting, thirst,
Diarrhea(yellow with bad odor)
Abortion
Subsequent infections not as severe
