- Treatment
- Immunity
- assoc with what?
A
- Strangles

horses to horse (oral, nasal), contaminated food, water infected droplets
- sever suppurative infection of upper resp tract and LN
fever, suppurative, resp distress

adheres to nasopharynx epi cells –> through resp mucosa –> LN
streptolysins kill phagos, M-proteins
- Cx, culutre nasal swabs, PCR, three neg to be negative
- penicillin, drain LN
- intranasal (MLV - good cause IgA - not passed on)
- purpurra hemorrhagia - highly fatal immune rxn
