Swine, sheep (some goat)

flooring/housing

infectious etiology

fractures

developmental

epidemiology: exposure to dirt lots, stressful event

acute clinical signs: lameness, abortions, diamond skin lesions, high fever, lethargy

those that survive develop arthritis and may have endocarditis

all forms can be treated with antiserum, penicillin, ampicillin, ceftiofur

Actinomyces/Truperella pyogenes

Strep and Staph species

Brucella suis

E. coli

Strep, staph, E.coli, Truperella

Strep, staph, E. coli

All of the above

None of the above

treat with penicillin, very carefully drain abscesses

clinical signs include: periarticular abscesses, intraarticular abscesses, spinal abscesses with associated posterior paresis (sit like dogs)

can pick up the organisms that can cause supp, arthritis and osteomyelitis through: tonsilar exposure, fighting wounds (post weaning, aural hematomas), dystocia, unsanitary practices (ear and tail docking), foot or limb abrasions

control by eliminating predisposing cause

Streptococcus suis

Mycoplasma hyorhinis

Hemophilus parasuis (Glasser's disease)

E. coli

treat Mycoplasma hyorhinis with tetracycline

treat Streptococcus suis with tetracycline

can't treat Hemophilus parasuis

prevent with vaccination for Streptococcus suis

foot trimming (trim away all undermined sole and hoof wall)

Footbaths/soaks should be done with 10% zinc sulfate and copper sulfate for 15-30 minutes every day for 6 weeks

usually 1 shot of long acting penicillin is enough

you can petrify the foot if you use a 5% formalin footbath for longer than 5-10 mintues

because of other pathogens

because foot rot will show up before then, if it isn't seen by then the new additions are in the clear

is called benign foot rot b/c it is caused by the same bacterial strains that cause contagious foot rot, but benign is found between the toes

is associated with dry conditions that slice the interdigital space and become contaminated by feces and urine

is treated essentially the same way as contagious foot rot (dry feet out with foot soaks, penicillin)

ovine interdigital dermatitis is caused by Fusabacterium necrophorum alone

caused by a lentivirus

transmission is through colostrum intake

the carpus is the most commonly afflicted joint

most infected animals develop disease

leukoencephalomalacia in kids <6 months old (progressive posterior paralysis)

hyperplastic synovitis-arthritis (those over 1 yr of age)

interstitial pneumonia

mastitis

conjunctivitis

same as respiratory agents (Mycoplasma capricolum, Mycoplasma mycoides)

clinically seen in 3-8 month old kids, high fever, painful joints, variable swelling, meningitis, conjunctivitis

treat with tylosin, florfenicol

prevention: pasteurize milk/colostrum
