− | |pagebody = | + | |pagebody = Actinomycetes organisms are gram positive bacteria that grow slowly on media and produce branching filaments. They are associated with opportunistic infections causing inflammatory responses and granulomatous reactions; animal pathogens include ''Actinomyces, Arcanobacterium, Actinobaculum, Nocardia'' and ''Dermatophilus''. |

| + | Actinomycetes organisms are non-motile, non-spore-forming bacteria which are anaerobic or facultative anaerobes that typically colonise mucous membranes. They will grow on enriched media and are non-acid fast, Modified Ziehl-Neelson negative when stained. |
| + | Clinically, this class of organisms includes ''Micropolyspora faeni and Thermactinomyces vulgaris'' - these are implicated in [[Extrinsic Allergic Bronchio-Alveolitis|Bovine Farmers Lung]] and ''Thermactinomyces vulgaris'' is associated with the pathology of [[Recurrent Airway Obstruction|RAO]] in horses. |
