The objective of this study was to determine the wildlife hosts of Mycobacterium avium subsp. paratuberculosis (MAP) in the Czech Republic. A total of 8 796 wildlife animals were examined by culture of faecal or tissue samples during the years 2002–2007. MAP was isolated from 12 (0.5%) out of 2 296 red deer (Cervus elaphus), two (0.2%) out of 835 roe deer (Capreolus capreolus), 78 (5.7%) out of 1 381 fallow deer (Dama dama), 28 (3.2%)out of 866 mouflons (Ovis musimon), four (2.5%) out of 162 chamois (Rupicapra rupicapra) and from one (0.1%) out of 805 wild boar (Sus scrofa). MAP was not cultured from 82 badgers (Meles meles), 55 martens (Martes foina), one pine marten (Martes martes), 25 brown hares (Lepus europaeus), five rabbits (Oryctolagus cuniculus), nine European polecats (Mustela putorius), two steppe polecats (Mustela eversmannii), two American minks (Mustela vison), four raccoon dogs (Nyctereutes procyonoides) and four Eurasian otters (Lutra lutra). MAP was isolated from three (2.0%) out of 149 small terrestrial mammals: one (5.9%) out of 17 brown rats (Rattus norvegicus), one (1.7%) out of 59 common voles (Microtus arvalis) and one (2.6%) out of 39 lesser white-toothed shrews (Crocidura suaveolens). Culture examinations of 34 house mice (Mus musculus) and 2 113 pigeons (Columba livia f. domestica) were negative. All 123 in vitro growing MAP isolates from wild ruminants were of IS900 RFLP type B-C1. One mouflon infected with a MAP strain which did not grow on the tested media was after IS1311-PRA-PCR assessed as being infected with a “sheep” strain. The RFLP type of the MAP isolate from the wild boar was of the RFLP type A-C10. Although the detection of MAP in wildlife in the Czech Republic was not very high, their role as a potential risk factor for cattle should be considered.
