Abstract
It is presumed that these bacteria are secondary invaders, with the primary agent either a Mycoplasma or a Parainfluenza 3 virus (St George 1971, 1972). Numerous other bacteria, presumably secondary invaders, have been described including Escherichia coli, Neisseria spp and Klebsiella spp. (St George 1972).Lungworms (Dictyocaulis filaria, Meullerus capillaris and Protostrongylus rufescens) have all been found in Australia (St George 1972). While lungworm was once relatively common, it is now rarely diagnosed, presumably because of the widespread use of broad-spectrum anthelmintics.Caseous lymphadenitis (CLA) (Corynebacterium ovis) sometimes causes lung abscessation. The prevalence of CLA has declined over the past two decades, presumably in part due to the adoption of vaccination (Bush et al, 2011).Aspiration pneumonia is occasionally encountered subsequent to the accidental inhalation of drenches and other products administered orally and because of plunge dipping.The important contagious respiratory tumours, sheep pulmonary adenomatosis (ovine pulmonary adenocarcinoma, Jaagsiekte) and maedi are exotic to Australia.REFERENCESBush RD, Barnett R, Links IJ and Windsor PA (2011).
