What does SIV stand for? - ANS-Swine Inluenza Virus
What is the main take home message about swine health? - ANS-health management
is less about treatment and more about prevention.
- biosecurity
- pig flow
- managing immunity
What does pig flow mean? - ANS-how we manage a population
How can we manage immunity? - ANS-protocols and procedures
What are the two parts of biosecurity? - ANS-Bioexclusion and biocontainment
What is bioexclusion? - ANS-how we keep disease/ things out
What is biocontainment? - ANS-not spreading diseases by changing shoes and
coveralls
How do things/ disease come into a pig farm? - ANS-- other pigs
- trucks
- feed
- semen
- people
- equipment
What are some farm-specific protocols for pig farms? - ANS-- introducing and
acclimating replacement animals
- people flow and sanitation
- equipment and trucks
- dead animals
,- birds/rodents/insects
- sanitation
Why is handling dead animals (pigs) problematic? - ANS-because of biosecurity, we
have trucks go from farm to farm and there can be a fomite
What are the proper boot protocols in swine operations? - ANS-change boots or use
cleaning stations properly
How are foot baths ineffective in swine barns most of the time? - ANS-because the
liquid is not cleaned out enough, the fecal material builds up and makes disinfectant
less effective
Describe multiple-site production system for pigs? - ANS-_ breeding and farrowing
barns on on the same site but different buildings
- once the piglets are in the nursery phase (day 19-24) they will be moved to a different
site
- after nursery, growing/finishing pigs are moved to a different site
Describe a single site production system for pigs? - ANS-All phases of pigs are all on
the same site but in different buildings (this is what KSU has)
What is the All-in, All out production term mean? - ANS-- pigs 1-2 weeks apart in age
- moved in together
- moved out together
- facility is cleaned and disinfected between groups
What respiratory disease is zoonotic? s - ANS-SWINE INFLUENZA VIRUS
How does SIV work to cause a disease? s - ANS-- virus enters the nasal tract and
causes damage to the epithelium
- organism destroys cillia, lungs cant clear themselves of debris and pathogens
- reduces ability of macrophages in the respiratory tract to combat microorganisms
What are the clinical signs of SIV? s - ANS-- respiratory sympotms (coughing and
sneezing)
- fever
What is the SIV incubation period? s - ANS-1-3 days
How long until SIV will resolve itself? s - ANS-5-7 days
SIV has ___ morbidity, ____ mortalitly. s - ANS-high , low
spreads VERY quickly
, What treatment is there for SIV? s - ANS-no specific treatment
- make sure water is available
- vx questionable
- antibiotics can be helpful to help control secondary bacterial infections if present
- anti inflammatories are recommended to help reduce a fever
What time of the year to you usually see SIV? s - ANS-fall and spring
How do we manage septicemic diseases in baby pigs? - ANS-- point of entry/ sanitation
( make sure we help manage to help limit it getting into bloodstream)
What do we see in growing pigs with septicemic disease? - ANS-- delayed point of entry
(bacteria gets in but takes a while to show signs)
- secondary problem (usually the thing that causes clinical disease)
- naÏve pig problem/ age spread
What age do we usually see streptococcus suis? and what can it cause? s - ANS-
nursery phase
- can cause an infection in the menages in the brain and cause neuro issues and a
fever
What signs do we see with streptococcus suis? s - ANS-- uncoordinated often with
uncrtolled eye movements
- as condition progresses the pig will fall over and thrash with a;; four legs on the floor
- death can control quickly especially if the pig is stressed
If you give a pig with streptococcus suis penicillin to late what will happen? - ANS-
neurologically damaged pig
How is streptococcus suis spread? s - ANS-nose to nose contact
stress induced
What are the 3 manifestations of streptococcus suis? s - ANS-- respiratory disease
- arthritis
- neurological
What kind of antibiotics does streptococcus suis respond well to? s - ANS-beta-lactam
antibiotics like penicllin
What is another name for glasserella parasius? s - ANS-glasser's disease
What kind of infection is glasserella parasius? s - ANS-bacterial
What happens to a pig when they have glasserella parasius? s - ANS-- multiple swollen
joints
- meningitis- sudden death
