first report of mycobacterium bovis isolation from a european fallow deer (dama dama dama) in iran

at present, most of iran is free of bovine tuberculosis (tb). the strategy of control and eradication in iran involves a tuberculation test and slaughter of reactors, a procedure transformed the present-day prevalence of tb into a sporadic occurrence. this paper describes the first report of bovine tuberculosis in a european fallow deer ( dama dama dama ) in iran. the deer was emaciated and found dead in the hoveize provincial zoo park. post-mortem examinations revealed multifocal granulomatous and suppurative abscesses in the lungs and mesenteric lymph nodes. these post-mortem indicators led the authors to suspect tb, and the pcr test and bacteriology tests confirmed it as an infection by the mycobacterium bovis . this survey discusses the important implications of such findings for wildlife, especially livestock, as well as for human tb disease control, because deer are often conserved in public zoos and humans often come into contact with them.
