<FlashCard questions="11">
|q1=What causes actinobacillosis in pigs?
|a1= ''Actinobacillus suis'' - a beta-haemolytic Gram-negative bacterium.
|l1=Actinobacillus suis#Introduction
|q2=Is actinobacillosis a zoonosis?
|a2=It is not considered a zoonosis but there has been a report of human infection after a pig bite
|l2=Actinobacillosis - Pig#Introduction
|q3=What herds are more susceptible to ''A.suis''?
|a3=High health status herds with lower immune challenges.
|l3=Actinobacillosis - Pig#Signalment
|q4=What environmental factors can exacerbate this disease?
|a4=
*Temperature fluctuation
*High humidity
*Mixing of pigs of different ages
*Overcrowding
Genetic make up and immune status can also influence infectivity rate and clinical signs.
|l4=Actinobacillosis - Pig#Signalmet
|q5=What age ranges of pigs are affected by this disease?
|a5= The disease affects suckling, weanling and fattening pigs, and adult pigs and it is thought that it colonises piglets within the first three weeks of life.
|l5=Actinobacillosis - Pig#Introduction
|q6=What clinical signs can be associated with actinobacillosis?
|a6=
* Lethargy, depression, '''erysipelas-like lesions''', abscesses, haemorrhage, vomiting/regurgitation and '''lameness''', '''multiple joint swelling''', dysphagia, lymphadenopathy, '''anorexia''', unthriftiness, '''pneumonia''' and '''sudden death'''
*'''Cardiorespiratory signs:''' tachycardia, murmurs, changes in heart rate, purulent or serous occulonasal discharges, sneezing, coughing, abnormal lung sounds, dyspnoea, '''cyanosis''' and open mouthed breathing
*'''Aural purulent mucoid discharge''',rubbing and scratching their ears and deafness
*Neurological signs such as head tilt, circling, '''temors''', '''paraparesis''' and '''ataxia'''
*Ocular signs such as '''corneal oedema''' and '''ulceration'''
In '''sows''' it can cause '''agalactia, mastitis, abortions, still births''' or '''weak piglets'''.
|l6=Actinobacillosis - Pig#Clinical Signs
|q7=How can ''actinobacillus'' be diagnosed?
|a7= By the isolation of ''A. suis'', from '''culturing infected tissue'''.
|l7=Actinobacillosis - Pig#Diagnosis
|q8=What can be seen on post mortem with this disease?
|a8=
*Serous or '''fibrinous exudates''' in the thorax and pericardium
*'''Ecchymotic haemorrhages''' in kidneys, lungs, liver, spleen and other organisms
|l8=Actinobacillosis - Pig#Diagnosis
|q9=What are the differential diagnosis for ''actinobacillosis'' in pigs?
|a9=
*Actinobacillus pleuropneumoniae
*Erysipelas
*Glasser's Disease
*Streptococcus suis
*Mulberry Heart Disease
|l9=Actinobacillosis - Pig#Diagnosis
|q10=How is actinobacillosis in pigs treated?
|a10=
*'''Ceftioufur, gentamicin''' and '''trimethoprim/sulfadiazine''' (good sensitivity)
*Ampicillin, neomycin, sulfadimethoxine and tiamulin (moderate sensitivity)
Culture and sensitivity is recommended.
|l10=Actinobacillosis - Pig#Treatment
|q11=How is actinobacillosis in pigs controlled?
|a11=
Currently there is no commercial vaccine for ''A. suis''. '''Routine biosecurity''' and '''disinfection''' should be followed and maintained.
|l11=Actinobacillosis - Pig#Control
