'''Tuberculoisis''' is a general term for diseases caused by the tuberculous group of bacteria, [[Mycobacteria spp.|Mycobacteria species]]. ''[[Mycobacterium tuberculosis]]'', ''[[Mycobacterium bovis]]'', ''[[Mycobacterium avium]]'' are host adapted to humans, cattle and birds respectively. All three types can produce disease in other species; ''Mycobacterium tiberculosis'' is the most host specific strain and rarely causes progresive disease in species other than humans, ''Mycobacterium bovis'' can affect a number of other species, see [[Bovine Tuberculosis]]. ''Mycobacterium avium'' is  [[Avian Tuberculosis]].

Infection can be via inhalation of infective droplets, ingestion of contaminated feed or water, and occasionally via coitus or via milk.
