Title:Adatok a paratuberkulózis hazai előfordulásáról - diagnosztikai fejlesztések és vizsgálati eredmények, 2006-2012
SUMMARY The authors report the first isolation of Mycobacterium avium ssp. paratuberculosis (MAP) from wild boar, red deer, red fox, swine, and buffalo in Hungary. Since 2006 continuous improvements were implemented and numerous (469) MAP strains were isolated from the whole geographic region of Hungary. The isolates were identified by a specific PCR, and additional molecular biological methods were introduced to distinguish the different MAP types. With the introduction of new culture media the isolation of sheep type MAP strains on solid media became possible. Analysing the data on the origin of the strains, the authors confirm the widespread presence of paratuberculosis in Hungary. MAP was isolated with the highest proportion from Komárom-Esztergom County. The numerous isolates from wild animals highlight the importance of their role as reservoir species in the maintenance and spread of the disease. The authors aim to point out that MAP infection causes significant economic losses to the farmers, which requires measures to get a better understanding of the actual state of paratuberculosis in Hungary.
