Q

facteur qui favorise express clinique de mycoplasma hyorhinis

A

diff souche
co-infect
environment

18
Q

reservoir

A

s. suis -> cochon
glasser –> truie
m. hyorhinis –> truie ou late severage
e. coli –> truie
rouget: pig amygdales + tissue lymphoides
a. suis: porc amygdales, cavite nasales, vagin

19
Q

pathogenie e. coli

A

souches avec facteur de virulence (fimbriae, aerobactine, cytotoxine) –> immunite difficiente –> (plaie/ ombilique) ou orale –> bacteremie –> septicemie ou sereuse

20

which ones are sporadique

A

rouget
e. coli

22
Q

which ones are colonisateur precoce

A

glasserella and a. suis

23
Q

pathogenie srrp

A

replication primaire tissue lymphoide
(amygdal, NL, poumon) –> viremie –> localisation organes lymphoides, poumon, autre replication secondaire

cellule cible macrophage/monocyte receptuer CD 163

24
Q

facteur a risque de circovirus

A

co-infection
regie
batiment
animaux

25
Q

traitement circovirus

A

antibio si infection secondaire

vaccin commercial tué, tres efficace, porcelet (after 10 days), truie, cochette

26
Q

prevention srrp

A

commercial vaccin vivent modifier IM, une souche, viremie, entre souche maybe, verrat/repro ou cochette

27
Q

MADEC

A

circovirus
decrease pression d’infection: tptv, lavage, hygiene, 1 auguille, parc hopital
augmenter resistance: colostrum, lmiter melange et adoption, condition env adequate

28
Q

ecoli porteur

A

truie ou post-sevrage (dans systeme GI)

29
Q

epidemio rouget

A

bacterie largement repandu
reservoir: porc (30-50%) dans amygdale et tissue lymphoide + PLEINS DAUTRE RESERVOIR

30
Q

diagnostique SRRP

A

prelevement : poumon + amygdale + NL
test: PCR

ou fluide orale : pcr/elisa

prise de sang: pcr/elisa

31
Q

prevention circovirus

A

vaccin commercial dispo
vaccin tuee 1-2 dose
porcellet ou truie/cochette

32
Q

pathogenie influenze

A

inhalation –> replication epithelium respi (bronche/bronchiole) –> ecoulement nasaux (1-7 jours post infection) –> bronchite necrosante

33
Q

traitement influenza

A

antipyretique + antibio si infection secndaire

vx: commercial tué usually for more than one souche

34
Q

diagnostique influenza

A

necropsie:
pcr poumon
isolation virale
sequencage H et N

vivant:
pcr - ecoulement nasal

fluide oraux

35
Q

diagnostic rhinite

A

identification des souches toxi pasteurella multocida

ecouvillon nasal/grattage amygdales

PCR/ANTIBIOGRAMME

36
Q

traitement/prevention rhinite

A

no treatment for progressive since irreversible just reduce contamination with MAT

prevention decrease pression d’infection
vx: pas commercial but autogene

37
Q

epidemiologie rhinite
