A

PO–> septicemia–> endotoic shock

venereal–> polyarthiritis–> reduce fertility in stallion/abortion or death of foal in 2-3 days/ polyarthiritis

18
Q

S.typhimurium var copenhagen pigeons CS

A

anorexia, weight, diarrhea, limping, cannot fly, breeding difficulty, apathic, PUPD, mortality
acute paratyphus- breeding
chronic paratyphus- one wing hanging down, intermittent secretion

19
Q

S.typhimurium var copenhagen pigeons

A

specific clonal lineage
PT2 and 99
carriers cause spread

20
Q

S.typhimurium var copenhagen pigeons Dx/Tx

A

culture/ rapid spread agglutination for Ab
antimicrobials
immune therapy hygiene
inactivated vaccine reduces severity does not prevent
hygiene
