Paratuberculosis(Johne?s disease), a chronic wasting disease caused by Mycobacterium
avium subspecies paratuberculosis(MAP), is a major cause of economic loss in the
cattle industry. In Korea, national monitoring of breeding stock for MAP has been
implemented. In this study, we report the results of serological testing to determine
the prevalence of MAP in breeding stock of Korean native and dairy cattle during 2008
and 2009. A total of 3,927 serum samples were submitted(3,692 Korean native cattle
and 235 dairy cattle) to Animal Disease Diagnostic Division, Animal, Plant and Fisheries
Quarantine and Inspection Agency. The samples were classified into four different age
groups for MAP : group 1(≤2 year, n = 1,509), group 2(>2 years to≤3 years, n =
486), group 3(>3 years to ≤4 years, n = 441), and group 4(>4 years, n = 1,491).
Overall seroprevalence of MAP in this study was 0.5%(21/3,927), which was much
lower than that of conventional cattle(1.2-16.4%) in Korea.Also, the seroprevalence was
determined by age groups : three of group 1(0.2%), two of group 2(0.4%), three of
group 3(0.7%), and 13 of group 4(0.9%) were seropositive for MAP, respectively.
Although seropositive samples were found in all age groups, the seroprevalence tended
to increase with age. Our study showed that the seroprevalence of MAP in pure-bred
breeding dairy cattle(0%) was lower than that in pure-bred breeding Korean native
cattle(0.6%).
