The objective of this study was to estimate the prevalence of M. avium subsp. paratuberculosis infection among beef and dairy cattle in Florida, USA. This was a retrospective seroprevalence study on serum samples from 32?011 cattle originating from 75 herds. Selection was limited to whole herds being tested for diagnostic purposes by owners considering

Johne's disease (paratuberculosis) is a chronic, granulomatous infection of the intestinal tract of ruminants caused by Mycobacterium avium subspecies paratuberculosis (MAP). There is no approved treatment, no known way to eliminate the infection once established, nor is there an effective vaccine for the disease. Johne's disease (JD) has emerged as an

Ovine Johne's disease (OJD) is commonly considered to be an ‘iceberg disease’ whereby the majority of infected individuals and the majority of the production losses associated with infection are subclinical, and only a small proportion of the infected animals develop overt, easily identifiable clinical signs.

SUMMARY Johne's disease was identified in sheep flocks on 6 farms in one area of the central tablelands of New South Wales. The sources of infection were not determined and no common source of all infections was identified. The disease was not diagnosed in cattle that were run on 4 of the farms.

Summary The pathology of Johne's disease in the sheep as it occurs in Scotland is given. On histological appearances it has been divided into four groups. Group 1 is characterised by masses of epithelioid cells. The pigmented variety of M. Johnei is most commonly present in very large numbers.
