Is actinobacillosis a zoonosis?	It is not considered a zoonosis but there has been a report of human infection after a pig bite	Link to Article
What herds are more susceptible to A.suis?	High health status herds with lower immune challenges.	Link to Article
What environmental factors can exaccerbate this disease?	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	[[\|Link to Article]]
What age ranges of pigs are affected by this disease?	The disease affects suckling, weanling and fattening pigs, and adult pigs and it is thought that it colonisesmin piglets within the first three weeks of life.	Link to Article
What clinical signs can be associated with actinobacillosis?	lethargy, depression, erysipelas-like lesions, abscesses, haemorrhage, vomiting/regurgitation and lameness and multiple joint swelling, 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. Dysphagia, lymphadenopathy, anorexia, and unthriftiness. Neurological signs such as head tilt, circling, temors, paraparesis and ataxia. Occular signs such as corneal oedema and ulceration. In sows it can cause agalactia, mastitis, abortions, still births' or weak piglets	[[\|Link to Article]]
