'''High health status herds''' with lower immune challenges are '''more at risk''' then conventional herds.  Piglets from high health status herds can suddenly die without any premonitory signs. Disease progression can be '''exaccerbated by excessive temperature fluctuation, high humidity, mixing of pigs of different ages and overcrowding'''. '''Genetic make up''' and '''immune status''' can also influence infectivity rate and clinical signs.

==Clinical Signs==

Clinical signs vary from fever, lethargy, depression, [[Erysipelas - Pig#Clinical Signs|'''erysipelas-like lesions''']], abscesses, haemorrhage, vomiting/regurgitation and '''lameness''' and '''multiple joint swelling'''.  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.

'''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.
