Swine Diarrhea Part I Flashcards
are gilt or sow litters more impacted by E. coli?
gilt litters
why is a warm, dry, draft free environment good?
increase piglet gut motility
encourage mobility, suckling and thus bathing of intestines with IgA
conserve piglets’ energy, reducing risk of hypoglycemia
are gilt or sow litters more impacted by rotavirus?
gilt litters
sow litters also affected
what ages are affected by rotavirus?
starts 1-7 days of age
no clinical signs in adults
who does coronavirus affect?
both sow and gilt litters
sows also affected
what is the mortality rate of coronavirus in the affected litter?
up to 100%
what does coronavirus do to the villi?
severe villous atrophy
who is affected by Clostridium perfringens type C?
both sow and gilt litters
no clinical signs adults
what is Clostridium perfringens type C?
very stable spore forming anaerobic bacterium
who does Coccidiosis affect?
both sow and gilt litters
not adults
no signs until 5 days of age
why does iron deficiency anemia occur?
milk is low in iron
most pigs need about 200 mg/day by day 3 of life
does E. coli make sows or gilts sick?
no
what does E. coli cause in litters?
high morbidity and mortality
within 24 hours of birth: signs
severe diarrhea
what can be used to treat E. coli?
spectinomycin
gentamycin
ceftiofur
enrofloxacin
are sows or gilts affected by rotavirus?
no
what are the clinical signs of rotavirus?
high morbidity, low mortality
creamy scour, pigs lose weight
some vomit
diarrhea
what is the primary cause of diarrhea in suckling pigs?
rotavirus
what does rotavirus do to the intestines?
infects/destroys mature enterocytes
how can you treat rotavirus?
warm, dry, draft free environment
dessicants in farrowing crates
full litter swaps
stop cross fostering, stepping in crates
are sows or gilts affected by coronavirus?
yes: off feed, lethargic, fever, diarrhea
what does coronavirus look like?
high morbidity and mortality in litter
vomiting, +/- blood
diarrhea
how can you treat coronavirus?
electrolytes to older piglets
humane euthanasia to pigs <2 weeks of age
antibiotics for secondary E. coli in older pigs
how can you generate immunity to the whole herd for coronavirus?
grind up chilled intestines from affected piglets
spray onto noses
does Clostridium perfringens make sows or gilts sick?
no
what is Clostridium perfringens like?
high morbidity and high mortality
diarrhea with blood
what is Clostridium perfringens type C?
very stable spore forming anaerobic bacterium
spores can live in environment for years
does coccidiosis affect sows and gilts?
no
what is coccidiosis like?
high morbidity, low mortality
starts at 5 days of age
diarrhea
do not grow well
what does coccidiosis do to the intestines?
sporozoites invade intestinal cells and cause epithelial cell damage to jejunum and ileum
