Paratuberculosis: A Potential Zoonosis?

Veterinary Clinics of North America: Food Animal Practice, 1996
Available literature on the controversial role of Mycobacterium paratuberculosis as an etiologic agent in human Crohn's disease is reviewed. Despite almost 15 years of investigation, the question of causal or consequential association between Johne's disease and Crohn's disease continues to linger.

Paratuberculosis in sheep: its possible role in the epidemiology of paratuberculosis in cattle

Veterinary Microbiology, 2001
A total of 50 sheep originating from 15 Dutch farms with a known paratuberculosis infection in their cattle herd, but with no history of paratuberculosis infection in their sheep flock, were examined for infection with Mycobacterium avium subsp. paratuberculosis (Map).

Mycobacterium paratuberculosis Monoassociated Nude Mice as a Paratuberculosis Model

Veterinary Pathology, 1991
In this study, a paratuberculosis (Johne's disease) model was developed by intragastrically dosing gnotobiotic athymic nude mice with Mycobacterium paratuberculosis. The mice infrequently shed bacilli from their intestinal tracts during the first 4 months after inoculation.

Paratuberculosis in sheep and goats

Veterinary Microbiology, 2015
Paratuberculosis is a chronic insidious, often serious, disease of the global small ruminant industries, mainly causing losses from mortalities and reduced productivity on-farm, interference in trading and, in Australia, profound socio-economic impacts that have periodically compromised harmony of rural communities. The pathogenesis, diagnosis, impacts

Immunology: Resistance to Paratuberculosis

Veterinary Clinics of North America: Food Animal Practice, 1996
Disease caused by Mycobacterium paratuberculosis involves a complex interaction of lymphoid and phagocytic cells of the peripheral and mucosal immune responses. For resistance to develop, animals must generate an effective cellular immune response to primary infections as well as multifocal exogenous and endogenous reinfections.

Economic Impact of Paratuberculosis

Veterinary Clinics of North America: Food Animal Practice, 1996
The economic impact of paratuberculosis has been estimated in dairy cattle for several areas of the United States and in some other dairy-intensive areas of the world. Losses are primarily due to decreased milk production and unrealized income related to premature culling.

Mycobacterium paratuberculosis heat shock protein 70 as a tool in control of paratuberculosis

Veterinary Immunology and Immunopathology, 2002
Paratuberculosis in cattle is a chronic intestinal disease in which a distinctive cellular reactivity of a Th1-type preceeds the phase in which antibody titers are easily detectable and the animal becomes clinically ill. During infection with Mycobacterium avium ssp.

[Diagnosis of paratuberculosis].

DTW. Deutsche tierarztliche Wochenschrift, 2003
Diagnostics of paratuberculosis infection is a difficult and complex field, that causes confusion, lack of understanding and frustration in practitioners, veterinary officers and last but not least farmers. In this review the various diagnostic approaches with their potentials, advantages and disadvantages and their limits are discussed.
