|q6=What clinical signs can be associated with actinobacillosis?
|a6= Clinical signs vary from fever, lethargy, depression, '''erysipelas-like lesions''', abscesses, haemorrhage, vomiting/regurgitation and '''lameness''' and '''multiple joint swelling'''
+
|a6=  
 
+
* Lethargy, depression, '''erysipelas-like lesions''', abscesses, haemorrhage, vomiting/regurgitation and '''lameness''', '''multiple joint swelling''', dysphagia, lymphadenopathy, '''anorexia''', unthriftiness, '''pneumonia''' and '''sudden death'''
More serious cases progress to '''pneumonia''' (clinical signs similar to [[Actinobacillus pleuropneumoniae#Clinical Signs| ''A. pleuropneumoniae'']]) and '''sudden death''''''Cardiorespiratory signs''' include tachycardia, heart murmurs, purulent or serous occulonasal discharges, sneezing, coughing, abnormal lung sounds, dyspnoea, '''cyanosis''' changes in heart rate and open mouthed breathing

*'''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
'''Aural purulent mucoid discharge''' and increased amounts of wax are present along with a '''foul odour'''.  Pigs can become '''deaf''' and are often found rubbing and scratching their ears. Affected animals are in a lot of pain and discomfort and suffer from dysphagia, lymphadenopathy, '''anorexia''', and unthriftiness.

*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'''.

Neurological signs include head tilt, circling, '''temors''', nystagmus, strabismus, decreased or absent menace response, ptosis, miosis or meiosis, photophobia, headshaking, opisthotonus, facial paralysis, '''paraparesis''' and '''ataxia'''. Further occular signs associated with this disease is '''corneal oedema''' and '''ulceration'''.

+
|l7=Actinobacillosis - Pig#Diagnosis

+
|q8=What can be seen on post mortem with this disease?
* Observation of clinical signs
 
* Postmortem and the presence of bilateral symmetrical vacuolation in the grey matter
 
* Western Blot Test (detection of PrP<sup>Res</sup>)
 
* Elisa Test
 
|l7=Bovine Spongiform Encephalopathy#Diagnosis
 
|q8=What are the most important control measures for BSE?
 
 
|a8=  
 
|a8=  
* The 1988 feed ban prohibiting the feeding of ruminant derived meat and bone meal (MBM) to ruminants
+
*Serous or '''fibrinous exudates''' in the thorax and pericardium
* Post mortem testing schemes
+
*'''Ecchymotic haemorrhages''' in kidneys, lungs, liver, spleen and other organisms
* Culling of infected cohort animals

|q9=Is BSE a zoonosis?
+
|a9=  
|a9= Yes, there is evidence to suggest that humans are at risk of developing variant Creutzfeldt-Jakob Disease (vCJD)from eating BSE infected meat.
+
*Actinobacillus pleuropneumoniae
|l9=Bovine Spongiform Encephalopathy#Control

*Glasser's Disease
 +
*Streptococcus suis

*Mulberry Heart Disease
 +
|l9=Actinobacillosis - Pig#Diagnosis
 +
|q10=How is actinobacillosis in pigs treated?
 
|a10=  
 
|a10=  
*All visible nervous and lymphatic tissue that are classified as '''specified risk materials (SRM)''' are removed during the processing of cattle
+
*'''Ceftioufur, gentamicin''' and '''trimethoprim/sulfadiazine''' (good sensitivity)
*The removal of any suspect animals from the human food chain. 
+
*Ampicillin, neomycin, sulfadimethoxine and tiamulin (moderate sensitivity)
*In 1996, cattle over the age of 30 months were eliminated from the food chain within the UK under the '''‘over thirty months scheme’''' (OTMS).  This ban has now been lifted and it is now compulsory to test all cattle over the age of 48months for BSE.
+
Culture and sensitivity is recommended.

Currently there is no commercial vaccine for ''A. suis''.  '''Routine biosecurity''' and '''disinfection''' should be followed and maintained.
